Measurement Location Check the flow profile on the graph to verify
the quality of the measurement location.
Relocate the sensor to a more suitable
location that exhibits better hydraulic
conditions (e.g., extend calming section).
Remove any existing dirt, sedimentation/silt,
or other obstructions from the front of the
sensor.
Smooth the flow profile by installing
appropriate baffle plates and calming
elements, flow straighteners, or similar
devices upstream from the measurement
location.
