DN15-25 high Accurate M-Bus Household Mechanical Heat Meters



DN15-25 high Accurate M-Bus Household Mechanical Heat Meters are mainly the small sized heat meters for household use. The M-Bus Mechanical Heat Meters DN15-25 can realize the long time distance metering with the centralized system with M-Bus function. Our DN15-25 M-Bus Heat Meters are very easy to
install, read and test but the M-Bus Mechanical Heat Meters DN15-25 must be installed on the horizontal direction. 


M-bus DN15-25 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.
