General
As with all flow measuring devices accuracy is highly dependent on proper location of the sensor in the piping system.
Irregular flow velocity profiles caused by valves, fittings, pipe bends, etc. can lead to inaccurate overall flow rate indications
even though local flow velocity measurement may be accurate. A sensor located in the pipe where it can be affected by air
bubbles, floating debris, or sediment may not achieve full accuracy and could be damaged. Badger Meter flow sensors are
designed to operate reliably under adverse conditions, but the following recommendations should be followed to ensure
maximum system accuracy:
1. Choose a location along the pipe with a length equivalent to 10 pipe diameters upstream and 5 pipe diameters
downstream of the sensor which are free of flow disturbances. Pipe bends, valves, other fittings, pipe enlargements, and
reductions should not be present in this length of pipe.
2. When the sensor is installed in horizontal piping, the preferred sensor orientation is vertical, on top of the pipe. If
trapped air or debris could potentially interfere with sensor operation the sensor can be installed as much as 45 degrees
from the vertical. Please note that when the sensor is installed “off the vertical”, impeller friction increases which may
affect performance at low flow rates and increase wear. The sensor should never be located at the bottom of the pipe,
as sediment may collect there. When the sensor is installed in vertical piping, it can be installed at any circumferential
position. Rising flow is preferred to reduce the effects of trapped air.
