    Battery operated or AC/DC powered Flanged type Ultrasonic Flow Meter uses transit-time ultrasonic technology in which the signal is transmitted and received alternately between 2 flow sensors and the “time of flight” determines the flow rate. Applications include both commercial and consumable water measurement. Long-term stability and a wide measurement range make it possible not only to measure water consumption, but also to monitor systems for water leakage. 

    Flanged type Ultrasonic Flow Meter Features:
    • Accuracy: +/- 0.5%;
    • Re-calibration or maintenance is easy, no processing interruption (just plug out the inserted transducers from pipe line, when re-calibration or maintenance is finished), can be hot-tapped
    • Calibrated in manufacture's lab, field setup is unnecessary.
    • Measurement is independent of fluid nature with wider applications than magnetic meters.
    • Available including up to 2GB event data logger, can search the event of totalizer flow, flow rate, velocity etc.
    • Parallel operation of positive, negative and net flow totalizer, while the output of totalizer pulse and frequency output are transmitted via open collector.
    • Power: 220VAC/24VDC or Battery optional
