These products comply with the national standard of the People’s Republic of China, GB/T 778-2018, which deals with drinking water and hot water meters. The quality control during manufacturing is carried out in accordance with the national metrological regulation JJG162-2009, which applies to cold water meters. The tubular battery-powered ultrasonic flow meter is a low-power intelligent industrial flow meter that makes use of time-difference measurement technology, pulse technology, signal digital processing technology, and error correction techniques. It has no mechanical moving parts, requires no parameter setting, can be installed at any angle, is less prone to damage, and needs minimal maintenance. It features built-in data storage and remote data transmission capabilities; the data measured on-site can be transmitted to the control room via wireless networks. This approach effectively solves the problems associated with traditional mechanical water meters, such as high starting flow rates, failure to measure low flow volumes, and difficulties in performing remote, real-time readings.
