The FTB2000 series Hall-effect turbine flowrate sensor is ideal for OEM applications involving low flow liquid monitoring. The low cost, coupled with 1 /2 % repeatability, makes it an ideal candidate for replacing dispensing timer systems. Unlike existing timing systems, turbine technology is not influenced by changes in system pressure caused by aging filters. The sensor’s standard power and output specifications make it easy to retrofit to existing controllers.

Rated 4 out of 5 by from small sensor at an inexpensive price Not the best sensor as far as flow sensors go but very inexpensive for a flow sensor it works good in our application of a chemical that is simalar to vegetable oil in viscosity we are using it with a plc and had to pull the voltage down from 24 v to 12 v then use a pull up resistor to be able to read pulses it word well at that point

Is this meter compatible with hydrocarbon fuels and hydrocracked base turbine oils?

Asked by: LR12
Thank you for your inquiry! There should be no chemical compatibility issues with hydrocarbon fuels but we cannot guarantee chemical compatibility given possible unknowns in the process. In terms of functionality the k-factor may need to be adjusted to accurately represent the pulses per gallon for liquids other than water. This can be corrected through a field calibration.

Is it necessary to install a filter at the entrance in order to protect the Flowrate Sensors from dirt and unwanted parts that are in the water. We want to ensure that the product will not damaged.

Asked by: Eli Maryan
Thank you for your inquiry about this flow meter. Yes, it would be recommended to use a filter of at least 10 microns to avoid any suspended particles to interfere with the moving turbine inside the flow meter.
