Product Description

ultrasonic water meter description

Our ultrasonic water meter has no moving parts, with high accuracy for years. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccurate 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.
