Product Description

High Temperature Ultrasonic Transducer For Flow Sensor, Water Meter, Heat Meter

The ultrasonic water meter has a pair of convection reflect type ultrasonic transducers. Each emits and receive the ultrasonic wave to calculate the cumbic flow in the closed pipe. The ultrasonic flow sensor measures liquid flow rate by transmitting ultrasonic wave in the liquid medium. In addition to flow metering, it can also be used for liquid level measurement.

Features:
• Mutual conversion of electric energy and sound energy with the piezoelectric effect of ceramic wafers
• Ultrasonic transducer adopts high-performance P-5 series piezoelectric crystal as the core, precise workmanship, strict inspection, long life, high sensitivity, accurate measurement, good consistency, etc.
• The transducer shell is made of stainless steel acoustic wedge and polymer engineering plastics to ensure the strength and corrosion resistance of the product. The wire adopts double-core shielded wire, which conforms to the national RVVP1 standard
