Product Description

product-790-380

No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccuracy measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.

Working Principle

Ultrasonic water meter is a new type of water meter that can detect the time difference caused by the change of speed when the ultrasonic beam propagates in the water upstream and downstream, analyze and deal with the flow rate of water, and then calculate the flow rate of water further.
