MGG/R Electromagnetic type Heat-energy meter
MGG/R electromagnetic heat-energy meter is a kind of instrument measured the
heat released of heat conducting fluid in thermal conversion systems .It used the
high accuracy and reliability electromagnetic flowmeter to measure the flow value,
then adopt Platinum thermal resistance to measure temperature ,it shows the best
performance in measurement.It can be widely used for measuring the heat in civilian
residential quarters, offices and institutions central heating, heating, air conditionin,etc
Main Features
It adopt 16-bit single chip computer to calculate data ,Platinum thermal resistance to
measure the heat and Electromagnetic flowmeter to measure the flow,high accuracy
stable and reliable operation ,excellent performance .Meassurement is independent
of heat conducting fluid’s density,viscosity ,pressure and conductive ratio.There are
no obstacle part in the measuring tube, no pressure loss ,not influented by the poor
water quality .Wide measurement range ,flow velocity can be set between 1m/s ~ 10m/s
Large-screen LCD screen backlight display Chinese version easily reading under strong
light or matt.It can display the accumulated heat, and the cumulative flow,transient heat,
transient flow,water temperature,water temperature,temperature difference simultaneously
and check out the flow velocity ,power failure records,etc. It adopt a random temperature
changes in enthalpy thermal modification principle to ensure that measurement precision
under the different water temperature. It has a unified DC signal and frequency signal
output function,and this feature is available in the heat and flow parameters to switch.With
the functions of batch processing (quantitative output), equivalent pulse output, keying
directly Clear.With digital communications of RS-485 (RS-232, M-BUS and HART is
optional) output ,to facilitate the achieve long-distance communications.With password
protected function, without password can not modify operating parameters .
