- Overview
EMF5000 series electromagnetic calorimeter Also called electromagnetic type heat energy meter, Is a new type of heat meter, Mainly used for household heat metering and charging system, Used to measure household The heating heat And unit Or the building heat, Can also be used in air conditioner metering occasions, The main structure is composed of a measuring tube parts With the converter section And the temperature measuring part, Can be completed on the inlet and outlet pipes in heating The heat of the hot water difference measurement, And with liquid crystal display Or remote signal.
EMF5000 series electromagnetic calorimeter Is a measurement of the thermal conversion system The heat carrying fluid heat released Measuring instrument. It uses high precision, High reliability of electromagnetic flowmeter as flow measurement, Adopting high precision, High stability Platinum thermal resistance as temperature measurement, The heat meter has very excellent measurement performance. Can be widely used in civilian residential，Office and business unit Central heating, Heating, Air conditioning heat metering
Main Features
Using 16 bit single chip to do the data operation, Platinum thermal resistance as temperature measurement, Electromagnetic flowmeter for flow rate measurement, High precision measurement, The use of stable and reliable, Excellent performance.
The measurement precision is not affected by heat carrying fluid viscosity, Density, Pressure and conductivity, The fluid distribution etc. The effect of parameter variation.
The measuring tube without resistance component, No pressure loss, Due to bad water quality impact.
Wide range of flow measurement, Velocity in 1m/s ～ 10m/s Range arbitrarily set.
Large screen LCD backlight source in the Chinese display mode, In the glare and light circumstances can clear reading.
Having heat accumulation, The cumulative flow, The instantaneous heat, The instantaneous flow, The water inlet temperature, The outlet water temperature, Temperature data at the same time display function, Can query and display velocity, Blackout records and other parameters.
Using random temperature change The heat enthalpy correction method, Guarantee in different temperature of Accurate measurement.
With a unified DC signal And frequency signal output function, And this function can be in heat And the flow parameters Switch.
With batch processing(quantitative output), The equivalent pulse output, Keying direct clearing function.
Have RS-485(RS-232, M-BUS and HART optional) Digital communication Output, To facilitate the realization of remote communication.
Has the password protection function, No password cannot modify the working parameters.
