Liquid Turbine Flow Meter
PPS Body, 0 to 5 VDC and Pulse Outputs
Series TFP-LP Liquid Turbine Flow Meters are suitable for a wide variety of
industrial, commercial, and laboratory flow applications. These meters utilize a turbine
wheel and electro-optical detection to convert flow rates into a linear 0 to 5 VDC output
signal for recording and data logging. Couple this unit with a Series TM2 Flow Totalizer
for a remote flow monitoring display. A power adapter or mating cable assembly is required
for operation.
