tlu series ultrasonic water meter
tlu series ultrasonic water meters are specially designed for urban water supply pipeline metering and household metering by means of propagation velocity difference, with the characteristics of low start-up flow, zero pressure loss, no movable parts, long-term stable operation and high reliability. they solve the problems of high start-up flow and non-metering of small flow of traditional water meters, and meet the needs of industrial use and have functions of calibrated pulse output, 4 ~ 20ma current output and rs-485 communication, applicable to various industrial sites. this product conforms to gb / t 778-2018 drinking cold water meter and hot water meter. the delivery inspection is in accordance with jjg162-2009 cold water meter.
main advantages
