Maretron FPM100 Fluid Pressure Monitor

Maretron FPM100 Fluid Pressure Monitor – FPM100-01

The Maretron FPM100 Fluid Pressure Monitor is a versatile and configurable marine data module that brings accurate fluid pressure and tank level monitoring to your vessel’s NMEA 2000® network. Designed for integration with multiple pressure transducers (sold separately), the FPM100 gives you real-time insight into water, oil, hydraulic pressure, vacuum, and even deep tank fluid levels — all viewable on compatible NMEA 2000® displays and monitoring systems. 

With support for up to six pressure transducer inputs, each channel can be individually configured to report pressure, vacuum, or tank-level data. In tank level mode, a pressure transducer mounted at the bottom of a tank lets you accurately monitor liquids in deep or irregularly shaped tanks — something traditional float-type sensors can struggle with. 

Whether used for water system pressure diagnostics, hydraulic system monitoring, vacuum detection on filters, or tank level sensing (fresh water, waste, diesel, etc.), the FPM100 turns analog sensor signals into NMEA 2000® data that can be shared across displays, chartplotters, and vessel monitoring software like Maretron’s N2KView®.

Technical & Installation Highlights

• Channels: Up to 6 pressure inputs (transducers required separately) 

• Modes: Pressure/Vacuum or Tank Level per channel 

• Network: NMEA 2000® certified backbone connection 

• Display Support: Works with Maretron DSM, compatible MFDs, and network software

• Mounting: Compact module for protected marine installation

Note: Pressure transducers are not included and must be selected based on the specific monitoring application (e.g., low-pressure for tanks, high-pressure for hydraulics). Many transducer options are available with different range ratings. 

Benefits

• Comprehensive fluid monitoring: Centralizes pressure and tank level data from multiple sources

• Flexible configuration: Each channel adapts to the pressure sensor type and installation needs

• Deep tank level measurement: Accurate for complex or tall tanks where conventional senders struggle

• Network visibility: Share vital data across your NMEA 2000® system for alarms, logging, and display

Common Marine Applications

• Water system pressure monitoring

• Hydraulic system pressure readouts

• Vacuum filtration monitoring (clog detection)

• Fuel, fresh water, waste, and other deep tank level monitoring

• Integration with vessel monitoring systems and alerts

Summary for the User

The FPM100 is an essential component for any comprehensive vessel monitoring system. It is particularly valuable for detecting clogged filters (via vacuum monitoring) or managing large fuel capacities where traditional sensors might fail.

Warning: Standard Maretron pressure transducers are not approved for use with gasoline. If you intend to monitor gasoline levels, you must use a specialized, third-party 4-20mA transducer approved for that purpose.

WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.
