M500 Electromagnetic Flowmeter – Environmental Monitoring Systems

The M500 Electromagnetic Flowmeter has been developed to meet the demanding requirements for Environmental monitoring systems and accurate metering of process and mining fluid supplies (including slurries and mixtures) but is equally at home in other water supply applications including urban water (recycled water, distribution network and revenue monitoring), irrigation.

General Applications

Electromagnetic flowmeters for the accurate flow measurement of any conductive fluid. Ideally suited to water and wastewater treatment plants, mining, environmental monitoring systems and general industry.
