- Commodity name： Mechanical Water Meter
Mechanical Water Meter
It is free of mechanical moving parts and wear, and has long servicelife and protection class of up to lP68. lt can work for a long term in waterand can be installed in multiple angles to minimize the pipe pressure loss.It can realize remote valve control, prepayment and wireless automatic adhoc network. The startup flow rate is low, the minimum flow rate can bemeasured accurately, and the range ratio, value R is up to 2501. lt uses themicro-power consumption technology and battery for power supply, andsupports various interfaces (photoelectric interface, RS-485 interface.M-BUS interface and radio frequency interface).
