Product Description
The ultrasonic water meter(SH7310) is a metering instrument that continuously measures, records, and displays the volume of water flowing through the sensor by use of the ultrasonic time difference method.
Products Description
- More precise measurement.
- Reliable design ensures long-term stable operation.
- The ultrasonic water meter can still accurately measure water usage at a low flow rate of 4L/h.
- The water meter can record total consumption as low as 1mL.
- The ultrasonic water meter is equipped with a 9-digit LCD that shows total consumption and instantaneous flow rate.
- Low-power circuit design with a service life of up to 12 years;
- The water meter supports both wired and wireless communication technologies for AMR (Automatic Meter Reading)
- Supports both forward and reverse measurement
- Ultrasonic water meter with no-moving-parts design, reducing wear and tear

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.
