20m depth measuring ultrasonic digital temperature sensor for water
flow meter
1.Introduction:
The ultrasonic probe is a device to transmit and receive ultrasonic
waves in the process of ultrasonic detection.The performance of the
probe directly affects the performance of the ultrasonic wave and
the detection performance of the ultrasonic wave.
2.Application:
This product specification is suitable for household ultrasonic gas
meter
