The
operation of a electromagnetic 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.
Features
--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.
--Site LCD displays instantaneous flow, accumulative flow, flow rate.
--Various types provided according to specific conditions.
