Product Description
The ultrasonic water meter(SH7310) is an intelligent instrument that uses ultrasonic technology to measure water flow. Compared to traditional mechanical water meters, it offers many advantages, such as high accuracy, no mechanical wear, and low maintenance costs.
Product Features
1. The design with no moving parts reduces the wear caused by friction.
2. A carefully designed structure enables the equipment to maintain stability and reliability during long-term use.
3. It can still accurately measure water usage at a low flow rate of 4L/h.
4. It can accurately record the total water consumption. Record total volume as small as 1mL.
5.9 digits LCD. Total volume and instantaneous flow rate indication.
6. Adopts a low-power circuit design, which extends the equipment's lifespan to up to 12 years.
7. Ready for AMR with wired and wireless communication technologies.
8. It supports a bidirectional metering function and can accurately record both forward and reverse water flow data.
9. The maximum displayable water volume is 9999 m³ (higher values can be set).
10. Provides higher precision in water flow measurement.
Working Principle
The ultrasonic water meter measures the time difference caused by the change in the speed of sound waves as they propagate with and against the water flow. By applying a calculation formula, the water flow rate is determined, and the cumulative water consumption is calculated based on the amount of water passing through the meter per unit of time.
AMR Ready
