Series TFM-LP Liquid Turbine Flowmeter

Brand: Dwyer Instruments, LLC

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.

Couple this unit with a Series FIV Flow Totalizer for a remote flow monitoring display.

A power adapter or mating cable assembly is required for operation.
Features
  • Rugged 316 SS Body
  • High Repeatability with Patented Microturbine Design
  • Design accurately measures Flow Rates with no zero drift and no required maintenance
