Characteristic:

1. Adopt ultrasonic measuring principle, no mechanical wear, long service life

2. Wide range ratio, metering level is better than Level D meter

3. Low starting flow, up to 0.0015m 3/ h. Drip metering can be realized

4. The whole machine has IP68 protection grade, and can work in water for a long time

5. Micro-power consumption technology, battery power supply, can work continuously for more than 10 years

Advantages:

·  Innovate valve design and break through traditional ball valve thinking

·  Cooperate with high-precision measurement and self-inspection function, and immediately alarm equipment abnormality and water use abnormality and other information

·  Convenient far and near end on-off valve design helps the water company to urge payment

·  The platform realizes remote automatic valve opening and closing through NB-IoT Internet of Things technology

·  The meter end uses the mobile phone APP function to realize manual valve opening on site

·  Sensitivity level of upstream/downstream flow field U0/D0
