Application

• Rectangular channel made of concrete, width 1m
• Partially filled
• Strong fluctuation between daily and nightly inflow

Definition of tasks

• Continuous flow rate measurement in a WWTP intake area
• Additional external level measurement shall be avoided
• Cost-efficient, for monitoring only
• No high accuracy is required
• Quick and easy sensor mounting

Solution

• The flow measurement system Type OCM F operates based on the Doppler principle.
• A wedge-shaped flow velocity sensor has been installed in the center of the rectangular channel.
• The flow velocity sensor has been equipped with a pressure measurement cell to avoid the need for an additional external level measurement.
