Ultrasonic water meter

Ultrasonic water meter



1. Designed strictly according to GBT 778.1-2007,ISO-4064,JJG162-2009 standard.
2. Low starting flow rate(Q1), avoid missing the small flow rate.
3. No pressure loss, IP68 of protction leve, suitable for varieties of work environment.
4. High accuracy make the water fees accurate and reliable.
5. No rotate abrasion, long service time.

[A brief description of the Ultrasonic water meter]

1:Very low starting flow, the minimum measurable flow rate of 0.01m / s
2:Ultra-low-power design, power consumption less than 0.00055W
3:Battery-powered can work for more than 6 to 10 years
4:ultrasonic sensors, no mechanical moving parts, maintenance-free design 10 years
5:ultrasonic meter bi-directional flow can be measured
6:measuring tube section mold casting, to ensure that no leakage
7:Accuracy ± 1%, ± 2%, ± 3% Optional
