Series TFM-LP Liquid Turbine Flow Meter

316SS Body, 0 to 5 VDC and Pulse Outputs

The SERIES TFM-LP Liquid Flowmeters utilize a turbine wheel and electro-optical detection to convert flow rates into a linear 0 to 5 VDC and pulsed output signal for recording and data logging. A power adapter or mating cable assembly is required for operation

Questions

Question
I use the TFM-LP Series Flow Meters for some of my OEM project. I am using the Stainless Steel Model at this point because the unit is measuring deionized water, 18 meg ohm deionized water in a clean room environment. Can I use the TFP-LP model with Deionized water? The only difference seems to be the material and pressure rating. The DI loop used is at 60 psi so I'm good with the pressure rating. Is the PPS material good for DI water?
Answer
The Dwyer Series TFM-LP Liquid Turbine Flow Meter is compatible with DI water. The PPS material, also known as Ryton, is also compatible with DI water.
