Revision 1.3 Page 1 ® ® 1 General 1.1 Introduction Congratulations on your purchase of the Maretr on Fluid Pressure Moni tor (FPM100). Maretron has designed and built your monitor to the highes t standards for years of reliable, dependable, and accurate service.
FPM100 User’s Manual o 16 programmable tank types includi ng Fuel, Fresh Water, Waste Water o Programmable tank number(s ) up to 16 per tank type o Programmable tank capacity 1.4 FPM100 Accessories Maretron offers the following accessories for the FPM100: • PT-V-0-1BAR-01 Pressure Transducer Vacuum to 1 Bar (14.
Revision 1.3 Page 3 ® ® o Configure for Tank Depth and Shape Configure or Program the Tank Depth (Section 3.3.5.1 ) Custom Calibration (Section 3.3.5.2 ) 1.6 Theory of Operation The FPM100 operates by measur ing the current transmitted by pressure transducers.
FPM100 User’s Manual Figure 1 - Graph of Transducer Accuracy vs. Tank Depth The pressure transducer you select must have su fficient range to measure the full height of the liquid column of a fu ll tank. The table in Figure 2 below shows the maximum depth that can be sensed by each pressure transducer type.
Revision 1.3 Page 5 ® ® 2.2 Choosing a Mounting Location Please consider the following wh en choosing a mounting location. 1. The FPM100 is waterproof, so it c an 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 tr ansducer is 2.4 to 3 times the maximum measurement pressure of the transducer.
® ® Pressure Transducer Ball Valve Tank Fitting 2.5 Connecting the FPM100 The FPM100 requires two types of elec trical connections: 1) the NMEA 2000 ® connection (refer to Section 2.5.1 ), and 2) the pressure transducer c onnections, which are described in Section 2.
FPM100 User’s Manual Figure 6 – NMEA 2000 ® Connector Face Views 2.5.2 Pressure Transducer Connections The FPM100 pressure transducer connections ar e made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the f our screws at the corner s of the unit detaching the splash guard from the unit.
Revision 1.3 Page 9 ® ® 3 Configuring the FPM100 The FPM100 has several configurable paramete rs, which are shown below including the default values. If you are not using the defaul t values, then you will need to refer to the corresponding section for confi guring the FPM100 appropriately.
FPM100 User’s Manual Page 10 Revision 1.3 3.2.2 Configuring Label Program this parameter with a text string which identifies t he particular parameter being monitored by this channel. Maretron display products will display this label text when yo u are selecting data to display.
Revision 1.3 Page 11 ® ® 3.3.2 Configuring Pressure at 4mA Program this parameter to matc h the pressure reading of the pr essure transducer when it is sourcing a current of 4mA. You can determine this value by examining t he specification of the pressure transducer being used.
FPM100 User’s Manual Empty Tank Depth Full Tank Depth Figure 8 – Empty Tank Depth and Full Tank Depth Parameters 3.3.5.1.3 Fluid Density In order for the FPM100 to properly convert pressure readings to tank levels using a rectangular tank calibration, it must be configured with the density of the fluid being monitored.
Revision 1.3 Page 13 ® ® 3.3.7 Configuring Tank Type As shipped from the factory, the FPM100 transmits the ta nk type as “Fuel”. You can reconfigure the FPM100 for any of these tank types: 1. Fuel 2. Fresh Water 3. Waste Water 4. Live Well 5. Oil 6.
