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
