Product Description

Tosilon High Accuracy Electromagnetic Flow Meter for Liquid (Ex Approved)
Design and Manufacturing according to UL, RoHS Standard

Introduction
TFE-Electromagnetic Flowmeter was developed based on principle of electromagnetic induction, I.E., when conductive liquid flows into measuring tube, the corresponding induction voltage signal, inspected from two electrodes installed on the tube, will be transmitted in transmitter and finally output digital signal.
TFE Electromagnetic Flowmeter is applied to measure the volumetric flow of conductive liquids and slurry in enclosed pipes, such as tap water, polluted water, mud, pulp, various acid/alkali/salt solutions, food slurry, etc.It has a wide range of applicant ambient, including oil interests, chemical industry, power plant, mining and metallurgic plant, water supply and sewerage works, light industry, food products factory, and so on.
