Hardware and Software Maintenance and Troubleshooting
Cleaning the Sealing Surface
Before installing a sensor in the meter body, clean the sealing surface
by completing the following procedure. The metal o-ring on the sensor
is used to seal the sensor cavity in the event that process fluid should
corrode through the meter body and enter the sensor cavity. Be sure not
to scratch or otherwise damage any part of the sensor, sensor cavity, or
sensor nut threads. Damage to these parts may require replacement of
the sensor or meter body, or may render the flowmeter dangerous.
NOTE
If you are installing a sensor that has been used before, clean the metal
o-ring on the sensor using the procedure above. If you are installing a
newly purchased sensor, cleaning the o-ring is not necessary.
1. Use a suction or compressed air device to remove any loose
particles from the sealing surface and other adjacent areas in the
sensor cavity.
NOTE
Do not scratch or deform any part of the sensor, sensor cavity, or sensor
nut threads.
2. Carefully brush the sealing surface clean with a soft bristle brush.
3. Moisten a cotton swab with an appropriate cleaning liquid.
4. Wipe the sealing surface. Repeat several times if necessary with a
clean cotton swab until there is minimal dirt residue picked up by
the cotton swab.

Sensor Installation
1. Carefully place sensor over the post in the sensor cavity.
2. Insure that the sensor is centered on the post. See Figure 4-13 for
an example of improper installation and Figure 4-14 for an
example of proper installation.
