M-Bus Mechanical Brass Body Residential Heat Meter DN20



M-Bus Mechanical Brass Body Residential Heat Meter DN20 are used for measurement of heat metering in all water based plants with
flow temperatures sensors. The M-Bus Mechanical Residential Heat Meters can realize the long time distance metering with the centralized system with M-Bus function. Our M-Bus Mechanical Residential Heat Meters are very easy to
install, read and test but the M-Bus Mechanical Residential Heat Meters must be installed on the horizontal direction. 


M-bus DN20 Mechanical Heat Meters 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.
