Descripion:
As water resources are becoming scarce, the demand for water measurement is increasing. The ultrasonic water meters are newly developed according to the national water meter standard GBT 778-2007 and the international water meter standard ISO-4064-1:2005,CJ-T188-2018 and EN13757.At the same time, it has a battery-powered super-long service life of large and small caliber ultrasonic water meter series.
The water meter adopts the latest domestic advanced ultrasonic time difference measurement technology developed by the company, which has the remarkable characteristics of high accuracy, ultra-low power consumption, wide range ratio, stability and reliability. Integration scheme is adopted in the structure. IP68 protection level can be achieved through good sealing, even if the instrument chamber water intake can ensure long-term reliable work.
Application:
This series of water meters solves the problems of traditional water meters such as easy blockage, idle running, small flow not measuring, countercurrent and so on. It can be widely used in urban water supply pipelines, District tables, water intake monitoring, farmland irrigation, as well as in a variety of industrial and agricultural sites.
