Flowmeters

Electromagnetic flowmeter solutions for precise flow measurement in water and process lines. The flowmeters can be tested and calibrated on KURASTECH Woltman and flowmeter calibration systems.

Product code: KEFM series

Electromagnetic Flowmeter

Working on Faraday's law of induction, the electromagnetic flowmeter measures the voltage generated by a conductive liquid passing through a magnetic field and determines the velocity and flow rate accurately. With no moving parts its maintenance cost is low, and its non-corrosive liner makes it suitable for almost all liquids with a conductivity of 5 µS/cm and above.

Instantaneous and total flow are shown on a 3-line LCD; analogue and frequency (pulse) outputs plus RS232 and RS485 Modbus interfaces pass the data to control systems such as PLC and PID. The flanged body mounts easily in horizontal or vertical lines.
