Battery Powered Ultrasonic Water Meter DN50 DN65 DN80 DN100 DN125 DN150mm RS485 digital water flowmeter IP68 Sandwich-type

ASW-1-K series sandwich-type ultrasonic water meter is a new type of water meter specially designed for

agricultural irrigation, garden management and water resources monitoring.

The water meter has some advantages,such as low cost, high measurement accuracy, low power consump-

tion, stable and reliable operation and so on. The thickness of the water meter is only 2 inches(50.8mm), which

saves installation space, and the IP68 scheme is adopted for all parts, so that the water meter can be used in

various harsh environment. The uniquestructure of the water meter makes the measurement basically free from

the influence of water quality and pressure loss, which is a major breakthrough in the agricultural irrigation water

measurement.
