The smart Heat Meters can display the accumulated heat, flow rate, instant flow rate, inlet water temperature, outlet water temperature, temperature difference and etc.
The smart heat 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(Heat Meter Counters) three parts. The smart heat meters are also known as smart energy meters. The smart heat meter is used to measure and display the water flow through the heat exchange system release or absorb heat. The smart heat 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 the smart heat 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 smart heat meter will calculate the released and absorbed energy through the calculator.
