The Measure of Flow Difference field (highlighted in green below) is based on the difference between the US/DS measured flow and the calculated flow (highlighted in blue).
These highlighted fields are described in the table below:
Field Name |
Description |
US Meas Flo |
The upstream manhole flow measured by the flow measuring device, in gallons per day. |
DS Meas Flo |
The downstream manhole flow measured by the flow measuring device, in gallons per day. |
US Calc Flow |
The flow calculated from the depth measurement using the Mannings equation in gallons per day. |
DS Calc Flow |
The downstream manhole calculated flow minus the upstream manhole calculated flow in gallons per day. |
Meas Flo Diff (gpd) |
The downstream manhole measured flow minus the upstream manhole measured flow in gallons per day. |
