Product Solutions for Water & Waste Water Industry

 

All water companies distribute drinking water through their pipeline distribution network. At strategic locations throughout the mains supply network, flow measurements have to be made to give a general overview of supply and demand and in some cases information about water losses through leakage along the pipelines.

 

Often relatively large pipes of varying pipe materials constitute the backbone of drinking water supply networks. Most of these pipes have been in operation for some considerable time. In some cases flow meters had been installed at the time of the network construction, in others, flow metering had not been considered at all.

Fluid Components International

fci

Fluid Components International solves flow and level measurement applications for industrial process and plant applications using patented thermal dispersion flow measurement technologies; With more than 40 years’ experience and the world’s largest installed base of thermal dispersion instruments, you can count on FCI to know your application and have proven solutions that will save you time and expense.

FLOW SWITCHES & LEVEL SENSORS

Flow Switches

  • Air, Gas, Liquid, Slurry Applications
  • Dual and Single Relay Output Models
  • No Mechanical Parts to Maintain
  • Apply in Fluids to 850 °F [454 °C]
  • Easy to Install and Set-up
  • SIL 2 Compliance (FLT93)

 

FCI flow switches utilize thermal disper­sion technology to provide fast response, accurate fluid flow sensing. FCI’s FLT Series and Nutec Series flow switch products provide an extensive selection for perform-ance, features, functions and environmental packaging options to meet a wide range of flow applications and installation re­quirements. The new FS10A is specifically designed for flow monitoring in analyzers and sampling systems.

Level Switches

  • High Reliability, No Moving Parts
  • Dual Function, Level and Temperature
  • AC, DC and Loop Powering Options
  • 3-Phase Detection
  • Interface Between Two Non-Miscible Fluids
  • SIL 2 Compliance (FLT93)

 

FCI liquid level and interface switches pro­vide fast responding and accurate fluid level alarm or setpoint control. They sense the tem­perature difference between a heated sensor and an unheated reference sensor, where the difference is greatest in the absence of liquid and decreases proportionally as the elements are submerged in various fluids with varying thermal conductivities. When submerged the heated sensor cools as it dissipates heat and in turn, a change in magnitude of the tem­perature difference. Because all fluids exhibit different heat transfer characteristics FCI’s highly sensitive level switch technology can detect historically difficult interface applica­tions between fluids such as liquids, gases, emulsions, slurries and foam, regardless of their physical properties.

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

 

e. Electrical transmitter (DMS50)

 

  • 1 or 2 effective directions
  • Teach-in function
  • Tare function
  • Simulator function
  • Unit selectable (kg, t, N, kN, Nm, bar)
  • Min- / max- value memory

Application:

 

  • Level measurement in complete tanks
  • Control of batch processes

OXYTRANS

456

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.
