Fiberglass Cover Model SH-XXX-XX-01(or 06)-XXX-XX
Installation
This section covers installation of Fiberglass Covers with Model
Numbers SH-xxx-xx-01-xxx-xx or SH-xxx-xx-06-xxx-
xx, where “x” is
any alphanumeric character. These covers are readily identified by
their having nut and bolt fasteners along their flange.
Remove the sensor cable access panel from the sensor upper cover
assembly.
Apply a coating of P/N 52307-01 PTFE Pipe Sealant (acts as a
lubricant during installation and sealant once cured) to the cover
gaskets. Note: This sealant is not used with stainless steel covers.
Install the sensor upper cover assembly over the sensor assembly.
Install the lower sensor cover. Hold the halves in place with spring
clamps. Note: Ensure the sensor cover does not pinch the sensor
cable. Note: Ensure the sensor cable connector is accessible through
the sensor cable access panel. (If necessary, reposition cover or
cable connector.)
Care must be taken during installation of the sensor band and sensor
band cover to ensure the sensor band cable does not become
pinched between the cover halves. The problem may show up as a
sensor failure during sensor tests and operation of the meter.
This potential problem is most likely to occur in small size meters (<6-
inch) due to the length and stiffness of the sensor band cable.
The following steps will help minimize this problem:
1. Visually look between the cover halves to ensure the cable is not
being pinched.
2. Once the cover halves are bolted in place and during installation of
the sensor band cable connector into the pre-amplifier through the
access cover, verify the sensor band cable is free and not pinched
between the cover halves.
3. If the cable is not free and appears to be pinched, remove the
sensor band cable from the pre-amplifier, unbolt the cover, free the
cable from between the cover halves, inspect for damage, and
then re-install if it appears undamaged. Note this on the
installation report for future reference.
