Hydraulic Jump

The flow measurement in open channels with the hydraulic relief method is carried out with the use, inside the channel or partially filled pipe, of a hydraulic modeller, a probe for measuring the level (in this case ultrasound, without contact with the liquid itself ) and an associated control unit for the conversion of the level in the corresponding instantaneous flow.
Thanks to the ever-increasing integration of the systems, a compact ultrasonic probe has been created that incorporates both the measurement of the hydraulic level and the conversion into its instantaneous flow rate.
