TFA Flowmeters

Overview

Our innovative TFA flowmeter is designed to meet the challenges of economically monitoring steam flow in small line sizes, so you can accurately assess energy use to help reduce consumption and improve performance in every area of your plant.

TFA Flowmeter

TFA Flowmeter

The TFA flowmeter is designed for use on saturated steam only and operates on the target principle, by measuring the force produced on a target by the fluid flow. This force is then converted into density compensated mass flowrate or power and is transmitted via a single loop powered 4-20 mA and pulsed output.
TFA flowmeters also incorporate a totalised flow function and EIA 232C (RS232) or EIA 485C (RS485) Modbus communications.
