Discharge Control of Stormwater Overflow Tank

Channel Networks - Stormwater Treatment Facilities


Application

  • Pipe diameter 0.3 m, made of galvanised steel
  • Partially filled
  • Low filling levels during night times

Definition of tasks

  • Continuous measurement and flow rate control on a stormwater overflow tank.
  • Detection of low nightly discharges.
  • Not more than one additional unit can be installed due to little space available in the switching cabinet.

Solution

  • A flow measurement using the Doppler method Type OCM FR with tube-shaped flow velocity sensor has been used.
  • In order to measure even lowest levels a Type i-Series 2-wire ultrasonic sensor  from the pipe top down has been selected.

Advantages

  • No need to install an additional controller in the switching cabinet due to transmitter-integrated 3-step controller with surge detection.
  • The sensor placement allows flow measurement from zero to maximum.
