Solution

  • A Q/h related ultrasonic volume measurement Type NivuMaster has been installed.
  • In order to maintain the measuring uncertainty as low as possible, an ultrasonic sensor with a very low dead zone (Type P-M3, dead zone 0.07m) has been selected to detect impoundage level.
  • All signals requested by the customer are transmitted from the transmitter to the control system and the on-site counter.
  • The sensor has been installed above the Venturi flume by using a standard wall installation angle.
