Page 9: Choosing A Mounting Location
® ® 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. -

FPM100 User’s Manual Keep in mind that the rated burst pressure of the pressure transducer is 2.4 to 3 times the maximum measurement pressure of the transducer. If the pressure transducer will experience pressure spikes in excess of the transducer’s maximum measurement pressure, use of a Pressure Snubber (PT-SNUB-01) accessory is highly recommended. -
