Electromagnetic Heat Meter is a kind of measuring instrument for measuring the heat released by the heat carrying fluid in the heat conversion system. It uses high-precision and high reliability electromagnetic flowmeter as flow measurement, and platinum thermal resistance with high precision and high stability as temperature measurement, so that the thermal energy meter has very excellent measurement performance. It can be widely used in the heat measurement of central heating, heating and air conditioning in civil residential quarters, office buildings and enterprises and institutions.

Characteristics of electromagnetic calorimeter

Using 16 bit single chip microcomputer for data operation, platinum thermal resistance for temperature measurement, and electromagnetic flowmeter for flow measurement, the measurement accuracy is high, the application is stable and reliable, and the performance is excellent.

·The measurement accuracy is not affected by the changes of parameters such as viscosity, density, pressure, conductivity and fluid distribution of heat carrying fluid.

·The measuring pipe has no resistance parts, no pressure loss and is not affected by bad water quality.

·The measuring flow range is wide, and the flow rate can be set arbitrarily in the range of 1m / S ~ 10m / s.

·Large screen LCD backlight display mode ，which can read clearly in strong light and no light.

·It has the function of simultaneous display of accumulated heat, accumulated flow, instantaneous heat, instantaneous flow, inlet water temperature, outlet water temperature, temperature difference and other data, and can query and display parameters such as flow rate, power failure record and so on.

·The enthalpy correction method with random temperature change is adopted to ensure accurate measurement under different water temperatures.

·It has a unified DC signal and frequency signal output function, and this function can be switched between heat and flow parameters.

·It has the functions of batch processing (quantitative output), equivalent pulse output and keying direct zero clearing.

·With RS-485 (RS-232, M-BUS and HART optional) digital communication output, it is convenient to realize remote communication.

·With password protection function, those without password cannot modify working parameters.
