Main features

●The YG-RLM (S) series of heat meters is a new generation of integrated single flow heat meters developed on the of the YG-RLM series for the European and Russian markets. This product, which uses advanced non-magnetic technology, is characterized by a simple structure, compact size, design, and light weight. It can be used to measure the flow rate of heating and cooling systems in living areas. The temperature range is from 4 to 95°.

●Units of measurement: kWh, total kcal are optional

●For single jet heat meters, communication is via M-BUS, RS-485 and pulse output is optional.
