B. Flow

The electronic flow monitoring with calorimetric measuring method does not need any moving parts in the flow (i.e. no turbine wheel or float). Therefore this sensor can be also used with aggressive media. Continuously measurements of smallest quantities of – for example – flavorings, liquors, water, etc. or chemically aggressive media is the main application field of the flow-meter HFK35-FIN.

 

a. Flow measurement of smallest quantities (HFK35-FIN)

 

Advantages HFK35-FIN:

 

• Several tube dimensions (6, 8 and 10 mm) adequate squeeze or screw terminals
• Flow: 0,001..10 l/min
• Pressure range: -1..+10 bar
• Accuracy: +/-2 %
• Application:Monitoring and measuring of smallestflows, Leakage control

 

b. Calorimetric flow measurement (HFK)

 

Advantages of further HFK-sensors:

 

• Process connection: TriClamp or G .
• Flow velocity water: 0,1..3 m/s
• Several evaluation electronics
• Application: Controlling and measuring

c. Electromagnetic flow measurement (MFI)

 

The voltage inductively produced by a conductive liquid in a magnetic coil depends on the flow velocity. This correlation is used for electromagnetic flow measurement. Advantages of this method are that no moving parts are necessary, that it causes only little pressure loss and that the same probe can be used

for a wide range of tube diameters.

 

Advantages:

 

• Variable process connection
• 14 diameters 3..100 mm
• Power supply 24 V DC
• Extremely compact
• Rotary head
• Completely made of stainless steel

 

Application:

 

• Flow measurement for all conductive liquids and pastes
• Process monitoring and control
• Continuous process dosing
• Filling of receptacles
• Batch-wise processes
• Minimum conductivity ≥ 5 μS/cm

 

C. Level

a. Hydrostatic level measurement (SA11 / TA1010)

 

The level measurement is done by measuring the hydrostatic pressure. Pressure is created by the liquid column above the sensor and is directly proportional to the fill level. The results can be visualized or processed by means of evaluation electronics adapted to the sensor.

 

• Level measurement for any tank shape via pressure measurement
• High accuracy ≤ 0,5 %
• Differential pressure measurement via double pressure measurement and evaluation electronics
• Complete stainless steel version
• Protection class IP65 or IP68
• Suitable for tank linearization via TA1010 or TA9648 evaluation electronics (6 Tank geometries as well as selectable special tank shape

 

b. Capacitive level measurement (UNICON-CL)

 

• Measuring ranges 0..200 mm to 0..3000 mm
• Units (mm, cm, in, ft, yd, m) programmable
• PTFE-measuring rod with G .-connection thread
• Compact design in 2-wire technology
• Outputs: 2 x 4..20 mA (for level and temperature), electrically isolated 2 x transistor switching outputs
• Protection class IP65
• Accuracy 0,5 % }2 mm
• Constant temperatures up to 120 °C

 

Application:

 

• Liquid, conductive adhering media

 

 

c. Potentiometric level measurement (MLP)

 

The MLP series continuously measures the level of all flowable media with a 3-pole rod probe. Using electrostatic induction effects allowed us to move the reference pole into the probe. Therefore an electric connection is not necessary any more at the tank. This enlarges the field of application; i.e. measurements in glass or plastic tanks.

 

• Dynamic measuring of fill levels for as little as 5 cm up to more than 2 m
• Minimum conductivity ≥ 5 μS/cm
• Measuring method independent of overpressure
• Only one measuring rod for metal or plastic tanks
• Applicable for permanent ambient temperatures up to 130 °C
• Several process connections
• Rod lengths with millimeter precision

 

d. Weighing measurement (DMS50 …)

 

• Transmitter without contact to medium
• Strain gauge input / Ex approval
• Measuring range from 0..2 kg to 0..5000 kg, maximum 0..100 t
• Basic accuracy 0,02 % to 0,1 %
• Repeat accuracy ≤ 0,03 %
• Max. overload 150 % to 200 %
• Protection class IP40 to IP67

OXYTRANS

Application and Measurement Principle:

Boiler feed water is water used to supply (feed) a boiler to generate steam or hot water. The feed water must be specially treated to avoid problems in the boiler and downstream systems. Untreated boiler feed water can cause corrosion and fouling. Corrosive compounds, especially oxygen, must be removed by deaeration systems. OXYTRANS allows to measure and control O2 concentration with highest precision. Centec deaeration skids based on membrane and column technology are generally equipped with OXYTRANS for highly efficient process control.

 

An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O2 is present the energy is transferred from the indicator molecules to the oxygen. By detecting the red light, OXYTRANS determines the O2 content with highest precision.

In nuclear power plants the heat generated by a nuclear fission process is used to drive a steam turbine which generates usable electricity. When an atom of nuclear fuel (uranium) absorbs a neutron the uranium will fission into two smaller atoms (waste) and release 1 to 3 neutrons. The kinetic energy of the waste is used to heat the water for the steam turbine. The neutrons are used to fission the next lot of uranium atoms, so the process continues. Boric acid (H3BO3) is dissolved in the reactor coolant where it absorbs the neutrons and thus controls the speed of the nuclear fission process. The concentration of H3BO3 is determined with highest precision based on density measurement.

For density measurement, the liquid consisting of 2 components flows through a U-shaped tube. While the tube is electronically excited to oscillate at resonance, the oscillation frequency is observed. Any change in the fluid density has an impact on the detected signal and can thus be identified. Based on the correlation between concentration and density, the concentration is calculated and displayed.

Within the Oil & Gas Industry there are various applications which require to measure flow of liquids such as oil, hydrocarbons or produced water. Oil platform operators for example have to ensure that they are adhering to the directives of oil discharge guidelines. They therefore have to find a way to reliably and accurately monitor the platforms’ discharges such as produced water. These circumstances lead to the situation that flowmeters often have not been installed on pipelines where monitoring was originally not necessary. In this case, instruments which can subsequently be installed to pipes of various materials and diameters without the need to interrupt ongoing processes are in high demand.

C. Specialized Turbine Meters

Flow Technology is recognized throughout the oil and gas industry for its ability to develop custom flow measurement systems which meet specialized application requirements. For example, a “high shock” design was developed for installations such as monitoring BOP activation where the meter may be subjected to extreme hydraulic shock loading. This design enables the turbine meter to withstand the water hammer effect without sustaining damage. Various other mechanical configurations, including manifold housings and meters with SAE Code 62 end fittings, have been utilized as the applications require.

 

Several different electronic packages have been developed for use in both surface and subsea applications. Watertight packages are available to house a standard pick-off with a low level output, an amplified pick-off with a square-wave pulse output, and linearizing electronics that provide a linear output of ±0.1% throughout the 100:1 dynamic range of the meter with a frequency and analog output. These subsea packages also have the flexibility to utilize various connector brands, such as SeaCon, D.G. O’Brien, or a connector manufacture as specified by the end user.

 

 

D. EL500 Series electromagnetic flow meters

Flow Technology’s EL500 Series electromagnetic flow meters proved to be an ideal answer to the customer’s demanding water treatment requirements. These meters allow accurate flow measurement in small line sizes with very low flow rates, and with no moving parts, provide reliable operation. MC106B panel-mount transmitters were selected to complement the EL500 meters. These economical transmitters can be integrally or remotely mounted to the flow meter, with the added capability of programming through faceplate push buttons.

 

System Description

A total of four EL500 flow meters and MC106B transmitters were employed for each mobile system to measure input and processed water at different stages of treatment. The EL500 meters offered key advantages such as: wide flow range, low pressure drop, chemically-inert Teflon liner, and 316 SS fittings and electrodes. The meters have a nonobstructed flow path with no moving parts, resulting in virtually no pressure drop and long service life.

 

The MC106B transmitters offered the convenience of a panel-mount design, and provided the display and flow signals required during the water treatment process.

Application and Measurement Principle:

An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O₂ is present the energy is transferred from the indicator molecules to the oxygen. By detecting the red light, OXYTRANS determines the O₂ content with highest precision.

Katronic Technologies Ltd. specialise in clamp-on ultrasonic flow meters and non-invasive process measurement instrumentation. The KATflow clamp-on flow meters work on the transit time ultrasonic principle. This, put simply, involves sending and receiving ultrasonic pulses from a pair of sensors and examining the time difference in the signal. This is a more direct method of determining flow rates than some other systems and provides reliable measurements.

 

Whether they are portable instruments or designed for permanent installation, the Katronic KATflow ultrasonic clamp-on flowmeters are cost effective devices for beverage to save resources, energy, and as a result costs. For these reasons and due to Katronic’s excellent and flexible customer service, leading companies of the brewing industry have decided to use KATflow Flowmeters.

 

General Advantages of Katronic Ultrasonic Clamp-On Flowmeters

1. No Shut Down:

By mounting the flowmeter on the outside of the pipe, there is no requirement to shut the flowing system down. This means no lost production.

2. No Engineering:

As the sensors are mounted externally to the pipeline, there is no need to conduct costly pipe modification, no need for specially trained manpower and no risk of any kind of leakage.

3. No Hidden Costs:

The only expense with a clamp-on unit is the purchase cost. Engineering work, down-time and trained staff are all expensive additions to more conventional metering solutions. Furthermore, on non-ultrasonic meters the hidden material costs of bolts, seals, washers etc. can more than double the price of an instrument.

4. Maintenance Free:

Katronic ultrasonic clamp-on flowmeters do not contain moving parts, which could wear out. Moreover, the sensor casings are manufactured of stainless steel and are not in contact with the flowing medium, which helps avoid corrosion. As a result, maintenance is not necessary.

5. High Accuracy:

For volume flow measurements, the KATflow flowmeters achieve an uncertainty of down to only 1.0% of the measured value depending on the conditions of the specific flow application. A decreased uncertainty of approx. 0.5% can be achieved by carrying out an on-site process calibration. In case of flow velocity measurements, the KATflow flowmeters achieve an uncertainty within 0.5% of the measured value.

6. User-Friendliness:

As the ultrasonic flow sensors are simply clamped onto the pipe surface, KATflow flowmeters can be installed without the need to open pipes. The sensors are fixed to the pipe using special metal chains, straps or mounting rails. Every instrument of the KATflow series is equipped with a set-up wizard and the Audible Sensor Positioning AssistantTM, which guide the user step-by-step through the installation process. As a result, it only takes a few minutes to install and set up the flowmeter.

Advantages Regarding Process Conditions and Hygenic Standards

 

1. Hygiene:

Installing a clamp-on flowmeters does not create intrusions which allow bacterial growth inside the pipe. This means that there is no risk of contaminating the product.

 

2. Variability:

 

As the sensors are never in contact with the flowing medium, the portable flowmeters can be used on many different applications regardless of the type of fluid. In addition to that, the instruments work on all common pipe materials and diameters from 10 mm to 3,000 mm.

 

3. Low Response Time:

 

With a response time of only one second, the KATflow Flowmeters can measure rapidly changing flow velocities.

 

4. High Temperature Tolerance:

 

The KATflow ultrasonic flowmeter sensors are designed to withstand temperatures ranging from -30 °C to 130 °C and more. As a result, they can be used on any application involved in or related to the brewing process.

 

5. Measuring Temperature Changes and Energy Consumption:

 

Whether you want to determine the cooling rates during the wort cooling process, or if you want to measure temperature related energy consumption to fine tune heating or cooling systems for higher system efficiencies: The KATflow 230 and 150 flowmeters enable the brewer to monitor the temperature changes of almost any flowing liquid.

 

6. No Pressure Drop:

 

Externally mounted sensors mean that the Katronic Flowmeters have no effect on the flowing liquid and will not cause a pressure drop across the measurement location.

 

7. Ideal for Monitoring CIP Processes:

 

Due to their contactless ultrasonic flow measurement technique, low response time, and the high temperature tolerance of the flow sensors, Katronic flowmeters are ideal to monitor CIP flushes.

• Power supply 24 V DC
• PNP- or NPN- output
• Programmable via GHMware

 

II. Conductive limit level measurement (MLR)

 

This is a very cost-effective but also flexible method for limit level measurement. The probe can be designed as single or multi rod. The probe rods can be subsequently shortened and bent to fit them optimally to the measuring situation. The evaluation electronics can be installed in the sensor head or in a switch cabinet.

A. CARBOTEC 

Application and Measurement Principle:

The content of carbon dioxide (CO2) has a strong influence on the quality and taste of beer, sparkling wine, soft drinks, mineral water and various other carbonated products. Therefore, breweries and other beverage and food companies continuously measure and control CO2 concentrations with highest precision throughout the entire manufacturing process.

CARBOTEC TR-PT: The carbonated liquid flows through a measurement chamber. By increasing the volume of the chamber, a gas phase is generated. The partial pressure difference of CO2 forces the CO2 out of the liquid into the gas. This changes the pressure inside the chamber. By pressure measurement, the CO2 content is calculated. CARBOTEC NIR: While transmitting a sapphire crystal, infrared light is reflected at the crystal surface which is in contact to the carbonated liquid. The CO2 molecules absorb the light and decrease the intensity. By intensity measurement, “true” CO2 content is determined. CARBOTEC NIR can be used to detect carbon dioxide even when CO2 is not the only gas in the liquid. Without any moving parts in the sensor head, the new generation of CO2 sensors is virtually maintenance free.

 

 

B. BEERMONITOR

Application and Measurement Principle:

Brewing is divided into milling, malting, mashing, lautering, boiling, fermenting, storage, filtering and filling. Fermentation begins after yeast is added to the cooled wort. During this stage fermentable sugars are metabolized mainly into alcohol and CO2. By combined measurement of density and sound velocity, both extract and alcohol can be determined. This is done after filtering, before filling and during optional blending. While the BEERMONITOR allows calculating the Original Gravity (OG), the PLATOMONITOR is used for OG determination only.

For density measurement, the liquid flows through a U-shaped tube. While the tube is electronically excited to oscillate at resonance, the oscillation frequency is observed. Any change in the fluid density has an impact on the detected signal and can thus be identified. At the same time, the speed of a sound pulse between a transmitter and a receiver is measured. The sound pulse is created by piezo-elements and moves perpendicular to the product flow. Based on the correlation between concentration and density resp. sound velocity, the concentration of the
3-component liquid is calculated.

 

 

C. CARBOTEC 

Application and Measurement Principle:

The content of dissolved oxygen (DO) has a strong influence on the quality and taste of beer, beverages and various other food products. Excess O2 can result in a significantly reduced shelf life. Therefore, breweries and other beverage and food companies continuously measure and control O2 concentrations with highest precision throughout the entire manufacturing process. Typical applications in food and beverage industries include the determination of dissolved oxygen in deaerated water used for processing the final product.

An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O2 is present the energy is transferred from the indicator molecules to the oxygen. By detecting the red light, OXYTRANS determines the O2 content with highest precision.

 

D. RHOTEC

Application and Measurement Principle:

Brewing is divided into milling, malting, mashing, lautering, boiling, fermenting, storage, filtering and filling. Lautering is the separation of the extracts won during mashing from the spent grain to create wort. During boiling hops are added which contribute aroma and flavor compounds to the beer. Lautering and boiling take place in the brewhouse and are controlled depending on the amount of extract. Breweries need to measure the extract concentration with precision to maintain beer quality. For the measurement of this 2-component system consisting of water and extract both density and sound velocity sensors can be used. RHOTEC is often preferred because of its even higher accuracy compared to SONATEC.

For density measurement, the liquid consisting of 2 components flows through a U-shaped tube. While the tube is electronically excited to oscillate at resonance, the oscillation frequency is observed. Any change in the fluid density has an impact on the detected signal and can thus be identified. Based on the correlation between concentration and density, the concentration is calculated and displayed.

 

E. SONATEC

Application and Measurement Principle:

 

Brewing is divided into milling, malting, mashing, lautering, boiling, fermenting, storage, filtering and filling. Lautering is the separation of the extracts won during mashing from the spent grain to create wort. During boiling hops are added which contribute aroma and flavor compounds to the beer. Lautering and boiling take place in the brewhouse and are controlled depending on the amount of extract. Breweries need to measure the extract concentration with precision to maintain beer quality. For the measurement of this 2-component system consisting of water and extract both density and sound velocity sensors can be used. SONATEC is often preferred because of its easy installation. SONATEC HW is designed for direct installation in the wort kettle. This instrument contains an integrated cleaning nozzle.

The speed of a sound pulse between a transmitter and a receiver is measured. The sound pulse is created by piezo-elements and moves perpendicular to the product flow. Based on the correlation between concentration and sound velocity, the concentration of the 2-component liquid is calculated and displayed.

Application and Measurement Principle:

Boiler feed water is water used to supply (feed) a boiler to generate steam or hot water. The feed water must be specially treated to avoid problems in the boiler and downstream systems. Untreated boiler feed water can cause corrosion and fouling. Corrosive compounds, especially oxygen, must be removed by deaeration systems. OXYTRANS allows to measure and control O₂ concentration with highest precision. Centec deaeration skids based on membrane and column technology are generally equipped with OXYTRANS for highly efficient process control.

An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O₂ is present the energy is transferred from the indicator molecules to the oxygen. By detecting the red light, OXYTRANS determines the O₂ content with highest precision.

A. SA Capacitance Level Switch

The capacitance level sensor measuring principle is based on the “capacitance effects”, when this level sensor is set on a silo, it will be formed a condenser between the detector electrode and the silo wall. The capacitance of this condenser varies proportional to the change of material specific inductivity (DK value) of the material stored in the silo, when the more material substances increased in the silo, the more capacitance value added simultaneously, then it will let his interior circuit “s resonant signal to create a bigger amplitude, and such a signal amplitude become more or less than factory default threshold value, the relay device will be energized.

B. EB RF-Capacitance Level Transmitter

Capacitance Level Indicator: Utilizes the capacitance formed between the sensing probe and the metallic vessel wall. A high frequency sine-wave is applied between the probe and the vessel wall. A change of the medium level will induce a change in the current of the applied sine wave. From Z=1/2pfc, when the capacitance in the vessel increase, impedance will decrease and current will increase. Vice-versa, when the capacitance in the vessel is small, the impedance will increase and current will decrease accordingly
