Flow Metering in Channel with Dry Weather Flume - Water and Wastewater

Definition Of Task

• Accurate detection of dry weather discharge and combined water discharge

Solution

• A measurement system Type OCM Pro has been used.
• To detect low volumes, the first sensor has been installed in the dry weather flume. Sensors 2 and 3 have been installed left and right of the dry weather flume on the side step. In combination with sensor 1 they detect flow velocities at higher levels or the discharge of combined water.

Advantages:

• Straightforward programming due to preset channel shapes.
• Utilisation of 2 analog outputs using appropriate scales for dry weather and rainy weather and hence high resolution of readings.
