Heat meter

Heat meter is a complex of devices designed for accounting for heat consumption.

The heat consumption is determined as the product of the volume of the heat carrier that has passed through the heat consumption system and the temperature difference between the inlet and outlet of it. The mandatory components of a heat meter are: a calculator, a flow sensor, and a pair of temperature sensors.

By appointment, accounting nodes are divided into commercial and non-commercial ones. Commercial heat meters are used for settlements with the heat supply organization. Non-commercial heat meters are proportionally distributed among consumers in cases where there is one common commercial meter installed and several non-commercial meters are installed after it.

All heat meters included in the state register, which have passed metrological verification and comply with the requirements of the heat supply organization, are allowed for commercial calculations.

Application area

Heat meters are used in heating, hot water supply, and ventilation systems of objects of various scales, from apartments and houses to neighborhoods and even cities. Heat meters can be installed in a system with virtually any heat carrier, such as steam or air, but heat meters for water have gained the most widespread use and are presented in this section.
