Product Introduction:
The DYDS-100 dual channel ultrasonic water meter is a newly developed battery powered large-diameter dual channel ultrasonic water meter based on Chinese national water meter standard GBT 778.1-2007, international water meter standard ISO-4064-1:2005, and Ministry of Construction electronic remote water meter CJ/224-2006 standards. This water meter adopts the company's latest developed unique ultrasonic propagation phase and time difference measurement technology, which has significant characteristics such as high accuracy, low power consumption, wide measurement range, stability and reliability. The structure adopts an IP68 protection scheme for each component, which means that each component reaches the IP68 protection level, and the instrument chamber can ensure long-term operation even if water enters. This series

The structure adopts an IP68 protection scheme for each component, which means that each component reaches the IP68 protection level, and the instrument chamber can ensure long-term operation even if water enters.
This series of water meters solves the problems of traditional water meters running idle and not measuring small flow rates. It can be widely used in urban water supply pipelines, household water consumption meters, water resource intake monitoring, farmland irrigation, and also applicable to various industrial sites.
