M-Bus Mechanical Heat Metering Apparatus

M-Bus Mechanical Heat Metering Apparatus

M-Bus Mechanical Heat Metering apparatus are used for measurement of heat metering in all water based plants with flow temperatures sensors. The Mechanical heat metering apparatus can realize the long time distance metering with the centralized system with M-Bus function. Our M-Bus Mechanical heat metering apparatus are very easy to install, read and test but the mechanical heat metering must be installed on the horizontal direction. 

M-Bus mechanical heat metering Apparatus can calculate the energy for every predetermined water volume. The energy calculation includes temperature measurement in flow and return as well as correction for density and heat content according to EN 1434.

The specification of M-Bus Mechanical Heat Metering apparatus is following:
