Product Description
Our ultrasonic water meter (SH7520) is an intelligent device that uses ultrasonic technology to measure water flow. It offers several advantages over traditional mechanical water meters, such as high accuracy, no mechanical wear, and low maintenance costs.
Product Features
- Display with error and alarm codes including leakage detection
- Data measurements are more accurate
- Bi-directional flow measurements
- Ultrasonic water meter is designed with no moving parts to reduce wear and tear
- The water consumption value can still be accurately obtained at a low flow rate of 3L/h
- Record total volume as small as 1mL
- 9 digits LCD. Total volume and instantaneous flow rate indication
- Low power consumption circuit board design extends service life up to 10 years
- Ready for AMR with wired and wireless communication technologies
