2.2 Choosing a Mounting Location
Please consider the following when choosing a mounting location.
1. The FPM100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the FPM100 can be mounted on a horizontal deck,
vertical bulkhead, or upside down if desired.
3. The FPM100 is temperature-rated to 55°C (130°F), so it should be mounted away from
engines or engine rooms where the operating temperature exceeds the specified limit.
2.3 Mounting the FPM100
Attach the FPM100 securely to the vessel using the included stainless steel mounting screws
or other fasteners as shown in Figure 3 below. Do not use threadlocking compounds
containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of
the plastic enclosure.

2.4 Mounting the Pressure Transducer
All pressure transducer accessories for the FPM100 are fitted with 1/4” NPT male threads.
Some pressure transducers measure gage pressure (pressure above atmospheric). These
transducers have a small plastic vent tube enclosed in the connecting cable. Special care must
be taken not to block or kink the vent tube, and not to expose the vent tube to moisture.
