® ® 1 General 1.1 Introduction Congratulations on your purchase of the Maretron Fluid Pressure Monitor (FPM100). Maretron has designed and built your monitor to the highest standards for years of reliable, dependable, and accurate service. Maretron’s Fluid Pressure Monitor (FPM100) is used to adapt up to six pressure transducers to ® the NMEA 2000 network (pressure transducers sold separately). This allows you to observe ® fluid pressures and tank levels anywhere on the vessel where

When you are using the FPM100 in conjunction with a pressure transducer to perform tank level measurement, it is important to understand the relationship of tank depth, the range of the pressure transducer, and the accuracy of the resulting tank le

FPM100 User’s Manual Figure 1 - Graph of Transducer Accuracy vs. Tank Depth The pressure transducer you select must have sufficient range to measure the full height of the liquid column of a full tank. The table in Figure 2 below shows the maximum depth that can be sensed by each pressure transducer type. This table assumes that water level is being measured. The maximum depth of diesel fuel can that can be measured varies from these figures slightly depending on the density of the d

® ® 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.

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. The snubber will dampen pressure spikes that will be seen by the pressure transducer. Please refer to the installation instructions pack
