Different from Ultrasonic Heat Counters,The Smart Heat Meters are used
for heat and cold energy calculation through the water. 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.
