The FTB-800 Series is a low cost Liquid Turbine Flow Meter with a 4-20 mA output available in 12 sizes covering flow ranges between 0.176 to 880 GPM. The FTB-800 Series Turbine Flow Meters are designed to meet the demands of the most rigorous flow measurement applications. The meter features a 304 stainless steel housing and rotor support, CD4MCU stainless steel rotor, and abrasion-resistant tungsten carbide rotor shaft and 316SS bearings. These materials help the meter to maintain accuracy and mechanical integrity when measuring the corrosive and abrasive fluids found in many industries.
When liquid flows through the casing of the sensor, the impulse of fluid will provide the blade with a rotation moment as there is an angle between the blade of the impeller and the flow direction. The blade will rotate as the friction moment and the fluid resistance are overcome, and it will reach a stable speed when the moments are at balance. Under certain conditions, the rotation speed of the blade will be in direct proportion to the flow velocity. Due to the magnetic conductivity of the blade, when located in the magnetic field generated by the signal detector (made of permanent magnet steel and coils), the rotating blade will cut the magnetic lines and periodically change the flux through the coil, thereby inducing electrical impulse signals at both ends of the coil. The induced signals, after being amplified and rectified will form a continuous rectangular impulse wave with certain amplitude which may be remotely transmitted to a display instrument indicating the instant flow and the cumulative flow of fluid. Within a certain range of flow, the impulse frequency f is in direct proportion to the instant flow of fluid flowing through the sensor.

early failure and poor customer service
installed this on my city water feed and it failed within a week
tried to get a factory replacement without removing piping to retro fit the new meter
5 week wait
unacceptable!

How to convert the 4-20 mA to flow rates? Is there a linear correlation between these two parameters?
Omega suggests that at 4 mA equals to ZERO flow and at 20 mA equals to the maximum flow rate and is linear between these points? How are these points defined?

What is the cable connection type used on this meter? Is it possible to purchase a replacement connector and cable? If yes, what is the part number? I have one of these flow meters, but have misplaced the connector & cable.
Thanks for your question. The part # for the connector is LWGY. Please use link to order below.

I'm interested in 804i & 810i, is there any calibration information if I purchase them?
Thank you for your inquiry! Unfortunately, we do not provide calibration documentation with the FTB-800 series flow meters

This flow meter can be used for 35% H2O2 liquid ? Model FTB-815-I Advise model no. for transmitter
Thank you for your inquiry! Unfortunately, the FTB-815-I would not be well suited for this application as the tungsten carbide rotor shaft will not be compatible with 35% H2O2. Please feel free to contact us using the email flow@omega.com with any further questions.

I have a FTB-815-I model and want to connect it to a DAQ. However, it seems that there are only two connectors 24V- and 24V+, while the manual indicates that the output should be 4 to 20mA. How do I connect this to a DAQ to read the current signal?
Thank you for your inquiry! The FTB-815-I is a two wire loop powered device. Typically the flow meter, a power supply, and a readout/recorder are all wired in a loop. The positive of the power supply goes to the positive of the flow meter, the negative of the flow meter goes to positive on the readout, and the negative of the power supply goes to the negative of the readout.

I got one FTB-815-I turbine meter 1", Could I conected in 1/2" size? Do you have a stainless steel 1/2" connector aditional accessory?
Thank you for your inquiry about the turbine flow meter. Unfortunately, there is no reducer available and in the event you must reduce the pipe diameter that much, please follow the straight run requirement upstream of at least 10x the diameter and 5x the diameter downstream.

How do I measure the 4-20mA output signal and transport it to my DAQ device?
Thank you for your inquiry about the turbine flow meter. Most DAQ systems can take a process analog input and if yours does not, then, best to contact our Data Acquisition Group at das@omega.com and they may have a module that will connect to your DAQ device.

I am purchasing the FTB-840-I flow meter. Can you provide the correct meter that will display the 4-20 output? Thanks
Thank you for your inquiry. The DPF64 is a display meter that will shw the flow rate only.
