General information

The Manhole flume is a low head loss, self-cleaning flow measurement device especially designed to easily fit into standard manholes.

No enlargement of the manhole riser or lid is necessary. The flume adapts to any standard waste water conveyance pipe. This flume allows accurate measurement over an unsurpassed flow range when compared to other inserts. The upstream approach and throat velocities significantly reduce solids deposition.

Due to the proportional head rise/flow rate characteristics for all Manhole flumes, the unit can be used in conjunction with a Badger Meter model iSonic 2000 ultrasonic flow meter to compute the flow rate.
