Electromagnetic Flowmeter Working Principle, Types Applications

         An electromagnetic flowmeter (magmeter) is a device that measures the flow rate of a conductive liquid by detecting the voltage difference across the liquid as it flows through a magnetic field. The voltage difference, also known as the electromotive force (EMF), is generated by the movement of the conductive liquid through the magnetic field. …

Turbine mass flowmeters

Impeller-Turbine Mass Flow Meters: The impeller, turbine type mass flow meter uses two rotating elements in the fluid stream, an impeller and a turbine. Both elements contain channels through which the fluid flows. The impeller is driven at a constant speed by a synchronous motor through a magnetic coupling and imparts an angular velocity to …

Helix flowmeter

What is Helix flowmeter? The helix flowmeter is a positive displacement device that uses two radially inclined helical gears to continuously trap the process fluid as it flows Working of helix flowmeter: The flow forces the helical gears to rotate in the plane of the pipe. Optical or magnetic sensors are used to encode a …
