Free Flow Metering Manhole Applications

Free Flow metering manholes are a fabricated assembly with standard open channel flow elements built into the base of a 4 ft. or 5 ft. diameter manhole.

The required flow conditions for use of a metering manhole are the same as those required for a particular open channel flow element.

Please refer to the typical installation and application data for details for a specific weir to determine its suitability for a particular application.
