A heat meter is a device which measures thermal energy provided by a heat source such as a boiler or heat pump, or delivered to a heat sink such as a central heating system or hot water cylinder, by measuring the flow rate of the heat transfer fluid and the temperature (ΔT) between the outflow and return legs of the system.
Heat meters consist of a flow sensor, a pair of temperature sensors, and a calculator. Typical applications of heat meters are the measurement of heat delivered to consumers by district heating systems, or the measurement of the heat output of say a heat pump, or the cooling output from a chiller.
