Solution

  • For this application 2 ultrasonic level meters Type NivuMaster with 2 sensors each have been used for average value measurement .
  • Average values coming from the sensors (combination of 2 sensors left and right of overflow trough) are routed to an universal transmitter (NivuCont). This unit converts the average values into volumes (Q/H-characteristic), summing the values subsequently up as overflow total
  • The total volume output is sent to the process control system (PCS) as analog signal
