Ultrasonic Water Meter

Ultrasonic water meter designed for accurate and stable measurement in residential and light commercial applications. Based on the time-difference method, it calculates flow by detecting the propagation velocity difference of ultrasonic signals in water.

The meter integrates measurement, calculation and display functions within a compact structure. Using low-power technology, it ensures efficient operation while maintaining high measurement accuracy.

With no moving parts, the design offers high stability, strong anti-interference capability and reduced mechanical wear, supporting long-term reliable operation.

Compliant with GB/T 778-2018 standards for cold and hot water metering, ensuring alignment with regulated metering requirements.

Features
