The
HYDROCAL-M4
thermal energy meter is equipped with
dedicated sections for the measurement of thermal energy of a
heating/cooling circuit and the volume measurement given by the
domestic hot and cold-water meters.
The meter is suitable for domestic applications with two-pipe
systems, in a thermal power plant or any other compatible
application. In residential systems, usually with two pipes systems,
the measurement of thermal energy takes place on a single section
both in heating and cooling cycle.
The picture below reports a typical connection diagram:
The device is equipped at the front with an LCD and two buttons (T1
and T2), useful for device initialization and readings.
