  At present, the heat metering market commonly used heat table is divided into mechanical heat meter(Mechanical Energy Meter) and ultrasonic heat meter(Ultrasonic Energy Meter).Heat Energy Meter is suitable for measuring the heat exchange, known as the heat transfer fluid or liquid absorbing thermal energy conversion equipment, which consists of a flow sensor, temperature sensor and heat calculator three parts. Heat energy meter (thermal meter), also known as Heat Meters , heat energy calculator, both measure heating system for heat and also measure heat absorption cooling system.

  Heat energy meter (heat meter) is used to measure and display the water flow through the heat exchange system release or absorb heat. Heat energy meter, is also known as energy meters. The heat energy meters are installed at the inlet pipe or outlet pipe to measure accurate metering and intelligent control of charges of the heat consumption. Its working principle is to install Heat Energy Meters in the heat exchange system, when water flows through the system, according to the supply and return water flow temperature, from the data from the flow sensors and temperature sensor as well as the water flow time, the heat energy meter will calculate the released and absorbed energy through the calculator.
