Single jet mechanical heat meter with M-BUS or RS-485 or Pulse output
Description
Description:
YG-RLM (D) series of heat meters are a new generation of integrated single-flow heat meters developed on the basis of YG-RLM series for the Europe and Russia market. This product uses advanced nonmagnetic technology and has the features of simple structure,
compact size, elegant design, and light weight. It can be used to measure the flows of both heating and cooling systems in living areas.
The temperature range is 4~95℃.
