Presentation
The new THERMAG VALVE CS611 ISONRG is an intelligent 2-way regulating valve with an integrated electromagnetic thermal energy meter. It delivers reliable energy control, precise energy calculation and billing-grade measurement compliant with EN1434 and MID 2014/32/EU. Designed to measure and monitor energy consumption in heating and cooling systems for both new and existing buildings, with native connectivity to building management systems (BMS) and IoT platforms.

Principle of operation
The electromagnetic flow meter works according to Faraday's law of electromagnetic induction: a voltage is induced when a conductive liquid passes through a magnetic field. This technology ensures an accuracy of 0.8% of the measured value (r.v.) for conductive thermal fluids, including mixtures with additives.
