Wheat meter walk or not, is based on the flow of hot water, and heating is not hot and not necessarily related.

The heating heat meter calculates the amount of heat released by the hot water that enters the user's home and passes through the radiators. Detecting the temperature difference and flow rate of water in and out of the user's home, it calculates the amount of heat consumed.

The heat meter goes along with the flow of hot water flow, the warm air is not hot does not mean that a little heat is not there, then, as long as there is hot water flow through, it will go word; if the warm air is not hot at all, that is to say, a little bit of hot water flow does not pass through the words, then the heat meter does not go word.

Thermal meter use and precautions

1, the thermal energy The exterior of the meter should have protective measures, such as meter box, to prevent vandalism or accidental damage.

2, the water quality of the heat exchanger system should be clean, softened and free of dirt in order to ensure smooth operation of the heat meter and not be clogged or damaged.

3, the heat meter must be installed filters, and regular cleaning of the filter.

4, the heat transfer system works normally, if you find the heat meter instantaneous flow is significantly reduced, which indicates that too much dirt in the filter, so that the pipeline becomes narrower, the water flow is reduced, this time should be timely clean up the filter.
