Introduction:
UTG21 series ultrasonic open channel flow meter can directly display the instantaneous and cumulative flow. The built-in EEPROM digital memory makes sure that the data will not lose in case of power failure. With different standards in various countries and can be widely used for measurement or monitoring of total water drainage. The measurement result is not affected by the water quality.
