• turbine flow sensor / transmitter
Kind of turbine flow product itself does not have on-site display, only traffic signal remote output flow signal can be divided pulse signal or current signal (4-20mA);. Low Meter prices, high integration, small size, especially for and the secondary display device, PLC, DCS and other computer control system used in conjunction.
Class turbine flow products divided into basic and explosion-proof (ExdIIBT6) are two, as shown in outline
