 Functions feature
This product is totally in accordance with the Standard of CJ128-2007's two grade.
Precise measurement function: Adopt the picoseconds high-accuracy time chip.
Display Functions: High-definition LCD displays accumulative heat/cold, accumulative flow,instantaneous flow, supply and return water temperature, supply and return temperature difference and accumulaitive working time.
Data record function: Automatically keep data inthe recent eighteen months include accumulative heat/cold and accumulative flow.It also can keep heating season data to let the users directly know the usage condition of heating and heat meter.
Infrared communication interface is equipped to have the funtion of parameter setting and concentrated meter reading.
M-BUS main wires remote data transmission function to achieve the function of parameter setting,flow calibration and concentrated meter reading The low power consumption during data communication makes the battery life longer.
