Insertion Mounting
To ensure optimum measurement performance, follow these guidelines when
insertion mounting the sensor:
??
Install the sensor into the pipe run so that the process flows directly into the
end of the sensor (see Figure 2-2).
??
Preferably, mount the sensor in a vertical position to eliminate the possibility
of trapped air bubbles from contacting its electrodes which can cause
measurement error. This also prevents loose pipe line sediment from
accumulating and obstructing the sensor electrodes.

compression fitting style sensor may be insertion mounted
into a pipe tee or vessel fitting. By reversing the compression fitting, the sensor
can be fastened to the end of an appropriate length pipe for immersion
mounting. The “longer version ” compression style sensor is intended to be
mounted into a ball valve assembly, enabling sensor removal without stopping
the process flow. Figure 2-l shows the sensor ’s general dimensions.
