Electromagnetic water meter with valve control

Electromagnetic water meter is new type of water meter.

Compared with other type water meter, it have much better R ralue, stability, and no pressure loss.

That's the reason that it become very popular in recent years.

My engineer add control valve on electromagnetic water meter.

The valve is battery powered also.

Customer could get pre-payment card and pay for the water they use.

Value will be closed if the payment used off.
