It is generally accepted that monitoring the vacuum after your Fuel Filter is the best way to detect clogging of your fuel filter and prevent untimely shutdown of your engines. This intermediate Fuel Filter Monitoring System monitors two engines and includes Maretron’s Fluid Pressure Monitor (FPM100) with vacuum transducers, a Run Indicator Module (RIM100) with Water In Fuel (WIF) sensors and a display (DSM250) to show these parameters anywhere on the boat. In addition, the display can be programmed to generate an audible warning when the vacuum reaches a critcal level, or water is detected in the fuel.
The following table shows the major components included within this example system plus a list of the information or data available for display.
| Product | Description | Available Data List |
| DSM250 | Display | Displays data in this list, monitors the data and sounds an internal buzzer if there is a problem |
| FPM100 | Fluid Pressure Monitor | Monitors pressure at outlet of Fuel Filters |
| RIM100 | Run Indicator Module | Monitors fuel for presence of Water |
- N2KBuilder file This file requires Maretron's free NMEA 2000® network design tool N2KBuilder® to be installed on your PC.
