Standard method flow device system solution

TIME:2019-05-01

The standard meter method water flow device of the Institute of Metrology will select different pipelines and different flows according to the needs during the flow meter calibration process, no matter how large the diameter pipeline is selected (the shaft is equipped with a photoelectric encoder, when the pump is running, the water pump is detected in real time The running speed is fed back to the inverter, which constitutes a double closed-loop control of pressure and speed, so that the pipe network reaches a stable pressure, so as to realize constant pressure water supply. The flow stability index of this scheme is 0.15%, and the pressure setting range is about (0.25~0.3)Mpa.
