FM230 electromagnetic flow sensor

The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and electrical conductivity

There are no flow-obstructing components inside the measuring tube, no pressure loss, and the requirement for straight pipe sections is relatively low

The sensor can be equipped with a grounding electrode to ensure good grounding of the instrument

It has the function of measuring flow in both forward and reverse directions

The converter adopts a liquid crystal backlit display, which makes reading easy in direct sunlight or in a dark room

The converter can simultaneously display the volumetric flow rate percentage, actual flow rate and cumulative flow rate

The installation on the pipe at a rotation Angle of ≤90° with the standard (type) improves the visibility of the integrated flowmeter

The converter is equipped with functions such as self-diagnostic alarm output, no-load detection alarm output, upper and lower limit alarm output for flow rate, and two-level flow value output

The application of electromagnetic flowmeters in multiple industrial fields

The electromagnetic flowmeter operates based on Faraday's law of electromagnetic induction. When a conductive liquid moves in a magnetic field to cut the magnetic field lines, it will generate an induced electromotive force in a direction perpendicular to the magnetic field and the flow direction. The flow rate of the fluid can be calculated by measuring the magnitude of this electromotive force. Its unique working principle makes it widely and crucially applied in industrial fields such as petroleum, chemical engineering, metallurgy, light textile, papermaking, environmental protection and food.

1. Water and Environmental Protection
