Abstract
Metering apparatus for installation in the bottom of a sewer well or manhole providing access to a sewer flow path and having an inlet and an outlet pipe at the bottom thereof. A hollow cylindrical section is provided for placement of one end in the outlet pipe, leaving the other end extending into the bottom of the sewer well. An inflatable collar is provided which surrounds the one end of the cylindrical section, and which, when inflated, provides a seal between the inside diameter of the outlet pipe and the outside diameter of the cylindrical section. The end of the cylindrical section which extends into the bottom of the sewer well carries an internally mounted metering flume situated so that the entire flow from the inlet pipe to the outlet pipe passes through the metering flume. The end of the cylindrical section which extends into the bottom of the sewer well is supported by means such as wedging blocks and is held in place against the wedging blocks by means such as a weight placed on top of the cylindrical section. A level indicator is provided to indicate the orientation of the metering flume relative to a horizontal plane. A contact plate is provided having a predetermined height above the bottom of the metering flume so that when a surface detecting device is utilized to monitor the surface level of the flow ahead of the metering flume, it may be directed to the contact plate to provide for a metering flume invert level measurement without contacting fluid flowing through the metering flume.
