Ultrasonic M-Bus or RS-485 Heat Meter

Product Description

APPLICATION
YG-RLM(C) series heat meters can be used to calculate heat or cold in apartment. This series is suitable for temperature range from 4 to 95ºC.
PRINCIPLE
Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flowing volume through meter.

Flowing volume signal comes from flow sensor,temperature difference comes from temperature sensor pair,as result the calculator will calculate heat according to the flowing volume and temperature difference.
