Electromagnetic Flow Meters

Electromagnetic flowmeters provide high-precision, bidirectional and stable industrial measurement in conductive liquids without causing pressure loss.

An electromagnetic flowmeter is an industrial measuring device designed to measure the flow rate of conductive liquids; it does not restrict flow and offers high accuracy. It can be used reliably for measuring water, wastewater, chemicals and liquids of varying densities. Thanks to the low-frequency excitation method and multi-sensor technology, it provides a stable and rapid response across a wide measurement range.

It offers various electrode and coating options for corrosive liquids. It ensures long-lasting use with rubber or PTFE inner surface alternatives. With its user-friendly menu and multiple communication options, it integrates easily into all automation systems.
