Installation guidelines
Explosion hazard. The instrument is not approved for installation in hazardous locations.
The monitoring location can affect the accuracy of flow measurements. Select sites that have a
continuous, steady flow and the least amount of turbulence. Turbulence can make it difficult to
identify an average velocity in the flow stream. Obstructions, vertical drops, pipe bends and elbows
can cause turbulence and affect the accuracy of the flow measurements.

Solution
Put the sensor in at least 10 times the highest expected level upstream of
the outfall.
Put the sensor in at least 10 times the highest expected level upstream of
the vertical drop.
Put the sensor in at least 10 times the highest expected level downstream
of the vertical drop.
Put the sensor in at least 10 times the highest expected level upstream of
the impediment.
Put the sensor in at least 10 times the highest expected level downstream
of the elbow, sharp turn or "Y" connection.
