KATRONIC

katronic

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.

A. CARBOTEC 

123

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

beer

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 

456

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

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.

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.
