4-20mA Output Magnetic Flowmeter (A+E 81F)
The operation of a emagnetic flowmeter or mag meter is based upon Faraday's Law, which states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.
--Large choice of liner materials suitable for drinking water, wastewater, chemicals and other liquids.
--Suitable for use in custody transfer applications.
--Measurement is independent of the flow profile.
--Abrasion and corrosion-resistant liners available.
--Electric conductivity of medium can be used for detection of product change.
--No additional pressure loss.
--No moveable parts and long working life.
--Two-way measurement system to detect the positive and negative flow.This magnetic flowmeter can be used to measure the volume flow rate of conducting liquid and seriflux in closed pipes, such as pure water, sewage, all kinds of acid-alkali-salt solution, slurry, pulp, paper pulp and food liquids.
--Site LCD displays instantaneous flow, accumulative flow, flow rate.
--Various types provided according to specific conditions.
