We made a comparison device for drip metering :
When the water is dripping, the Powermax ultrasonic water meter is still measuring, but the mechanical water meter does not measure at all.
Powermax ultrasonic water meters are more accurate(more billable revenue), easy to maintain,and least expensive to own.
Powermax ultrasonic water meter can effectively identify normal water or rotation and effectively solve the problem of water meter rotation or idling.
