TLU series ultrasonic water meter

The TLU series ultrasonic water meter adopts the propagation speed difference method and is specially designed for urban water supply pipeline metering and household metering. It has the characteristics of low starting flow rate, zero pressure loss, no movable parts, long-term stable operation, and high reliability. It solves the problem of high starting flow rate and small flow rate not being measured by traditional water meters, and is designed to meet the needs of industrial use. It has functions such as calibration pulse output, 4-20mA current output, and RS-485 communication, and is suitable for various industrial sites. This product complies with the national standard GB/T 778-2018 "Drinking Cold Water Meter and Hot Water Meter" of the People's Republic of China. The factory inspection is based on the Measurement and Verification Regulations of the People's Republic of China JJG 162-2009 "Cold Water Meter".
