Heat meter work principle and structure

Pieces heat meter definition
Heat meter is used to measure and display current flows through heat exchange system release or absorption heat energy meter.
Pieces working principle

The water in the heat exchange system installed heat meter, according to the flow sensor given flow and pairing temperature sensor given into, backwater temperature signal, as well as the flow of time, through the calculators calculate and display the system release or absorption of heat energy, the formula is as follows:

Type: Q - medium release heat kJ;
Qm - through heat meter of reheat liquid instantaneous mass flow kg/s;
∆ h - heat transfer loop of the inlet temperature and outlet temperature of the corresponding heat transfer liquid enthalpy difference than kJ/kg;
T - time s.

AKR pieces - C type ultrasonic thermal scale advantages
So imported precision electronic device, high measurement precision, low power consumption, good stability,
So no dirt deposition corner, completely free of medium impurity, chemical material and magnetic material interference effects, to the situation of water quality.
So measuring mechanism without moving parts, no wear, long service life,
So loss of pressure minimal, to improve heating quality.
So to adapt to a wide range, cold hot amphibious;
Pieces of the heat meter part
So flow sensor
Installed in the heat exchange system, used for collecting water flow and a flow signal components.
So pairing temperature sensor (PT1000)
In the same heat meter, and separately used to measure the heat exchange system of inlet and outlet temperature of a pair of measuring characteristics consistent or similar temperature sensor.
So calculator
Receiving from flow sensor and pairing temperature sensor signal, heat (cold quantity) calculation, storage and display system of exchange heat (cold quantity) value.
