product presentation ：
The ultrasonic water meter is an intelligent metering device integrating temperature sensors, flow sensors, and computational modules. Its calculation module accurately measures water flow by collecting temperature differences and acoustic wave signals through sensors, combined with time difference analysis principles. This equipment provides critical data support for various pipeline system applications, primarily used in residential water metering, centralized air conditioning system monitoring, and industrial equipment flow control.
