STRUCTURE:
The
heat meter consists of integrator,
temperature sensor and special flow meter.
In
addition to its high measuring accuracy,
the meter has up to 16 display items and can record various
operating parameters,
which provide important reference value for management of heating
system.

Precaution for installation:
1.
Control valves are required to be installed at meter’s inlet
and outlet, for easy maintenance.
2.
Filter is needed at inlet of meter to avoid influence of
foreign materials on metering accuracy.
3.
Heat piping must be flushed before meter installation.
