Based on the traditional mechanical single-jet rotary vane wheel dry dial water meter, the direct-reading water meter with long-distance transmission (remote reading available)is made of photoelectric sensor and intelligent communication module, which is designed on the basis of the traditional mechanical single-jet rotary vane dry-type water meter. This phenotype adopts the patented technology of integrated photoelectric direct reading, the sensor is isolated from the counting gear, and there is no mechanical contact. The counter is vacuum-treated, isolated from the air and water measured, so that the counter is always clear and free of atomization. The meter adopts sealed waterproof treatment and has anti-magnetic function.
