Scope
The heat meter measures the thermal energy consumed by the apartment directly in gigacalories (Gcal) and does not demand additional recalculations.
The device is not intended for installation on each radiator of heating separately since the difference of temperatures between entering and leaving pipelines is too small for calculations.
On the screen the device constantly displays value about the measured thermal energy from the moment of inclusion. The same values remain in non-volatile memory. Besides, the device has potential of viewing of additional values on the display which it does not show constantly, but keeps in non-volatile memory. To it parameters belong:
- thermal energy (Gcal, kcal, GDzh, MDzh, MW · h, kW · w);
- volume (or weight) heat carrier (water), m3 (t);
- water temperature in the giving and return pipelines, °C;
- heat carrier temperature difference in the giving and return pipelines, °C;
- the water volume measured by the water counters connected to pulse entrances, m ³
At the same time, the heat meter conducts data archives of values, the number of archival records depends on period type:
- monthly integrated (accumulated) – not less than 144 months (records);
- monthly – not less than 144 months (records);
- daily – not less than 62 days (records);
- hourly – not less than 48 hours (records).
Besides, the heat meter registers essential events in the special magazine in which finds room not less than 100 events (records).
