2.3 Mounting Considerations
Mounting considerations may vary (Flanges, Compression
Fitting, etc.) depending on the application. For underground
tanks, the probe is generally mounted in the riser, resting on
the bottom of the tank. Spacers are used to hold the sensor in
the riser and a cable is suspended from the tank cap.
While most underground tanks are horizontal and fairly
standard in design, above ground tanks vary considerably. The
requirements for mounting these probes are fairly simple.
Since the sensor requires a float to provide level position, there
is a minimum size required for insertion of the float into the
tank. It is recommended that a minimum of 2” diameter be
used for the most reliable system.
The size and material of the float being used will have a slight
impact on the overall accuracy of the measuring system. In
general, the larger the float the easier it is to provide a high
accuracy measurement.
