Best Nmea 2000 Fuel Flow Sensor for Maretron Networks

#1 · Best Overall

1. Maretron M1AR Fuel Flow Sensor

• dimensions: 6 x 4 x 4 in
• Weight: 2 lb
• Material: Metal

Best for: Low-flow FFM100 installations.

Why it ranks #1: Designed for the FFM100, it measures 2–100 LPH and lists a 1/4-inch NPT female port, aluminum housing, and 1-meter cable.

The M1AR’s stated 2–100 LPH flow rate and explicit use with the FFM100 monitor make it a targeted option for buyers assembling that Maretron sensor-and-monitor combination. Its 1/4-inch NPT female port and one-meter cable add concrete connection and cable details for planning an installation.

The 2–100 LPH range gives buyers a defined operating window, while the stated 1/4-inch NPT female port provides a specific connection detail to compare with their setup. Compatibility with the FFM100 monitor clarifies the intended pairing, and the one-meter cable gives a fixed length for routing considerations. The aluminum housing, 1000 PSI maximum operating pressure, and stated -40 to 80°C operating temperature further describe its listed construction and operating limits.

Skip it if you need more than one meter of sensor cable for your planned routing; the supplied cable is one meter long.

Choose this Maretron M1AR when pairing a sensor with an FFM100 and the 2–100 LPH range and female NPT port suit your setup. Check that its one-meter cable reaches your intended routing path before installation.

#2 · Highest Capacity

2. Maretron 25–500 LPH Sensor

• dimensions: 6 x 4 x 4 in
• Weight: 3 lb
• Material: Plastic

Best for: Wide-range flow applications.

Why it ranks #2: Its stated 25–500 LPH range reaches well beyond the M1AR’s 2–100 LPH range, though the listing does not specify FFM100 compatibility.

A stated operating range of 25–500 LPH, also given as 6.6–132 GPH in the title, is the defining reason to consider this Maretron fuel flow sensor. Those two units make the listed range easier to assess against a buyer’s preferred measurement system, while the product is identified as an electronic sensor.

The 25–500 LPH specification provides a broad stated operating span, and the title’s equivalent 6.6–132 GPH figure offers another way to evaluate whether that span suits the intended application. Maretron identifies the item as an electronic sensor, and its listed 6 x 4 x 4-inch dimensions help with space planning. The supplied details do not name a compatible monitor, connection type, or installation method, so this listing alone cannot settle those parts of a system plan.

Skip it if you need a listed monitor pairing or connection type before selecting a sensor; neither is specified here.

This Maretron sensor suits buyers whose required flow range falls within the stated 25–500 LPH span and who can verify system connections separately. Its listed dimensions support space planning, but the supplied details do not name a monitor pairing.

#3

3. Maretron M1AR 2–100 LPH Sensor

• dimensions: 6 x 4 x 0.1 in
• Weight: 3 lb
• Material: Plastic

Best for: 2–100 LPH sensor shoppers.

Why it ranks #3: The 2–100 LPH range matches the other M1AR listing, but this entry provides less installation detail and does not state FFM100 compatibility.

A stated 2–100 LPH range gives this Maretron fuel flow sensor a concrete selection criterion for buyers matching a sensor to expected fuel flow. The title names that range directly, while the listing identifies the product as a Maretron sensor and gives 6 x 4 x 0.1-inch dimensions for space consideration.

The 2–100 LPH title specification lets buyers compare the sensor’s stated range with their application, rather than selecting from a product name alone. Maretron is identified as the brand, and the listed 6 x 4 x 0.1-inch dimensions provide a physical reference for placement planning. The supplied information does not state a port type, cable length, monitor pairing, or operating pressure, so those details cannot be evaluated from this listing.

Skip it if you need a specified port type, cable length, or monitor pairing before choosing; those details are not supplied here.

This Maretron sensor fits buyers whose application matches the stated 2–100 LPH range and who can establish connection details separately. Use the listed dimensions as a planning reference, and do not assume a monitor pairing from the supplied information.

Best for: NMEA 2000 sensor-interface buyers.

Why it ranks #4: The listing explicitly identifies NMEA 2000 compatibility and says the FFM100-01 interfaces fuel-flow sensor data to the network.

The listing explicitly says the Maretron FFM100-01 interfaces data from fuel flow sensors to an NMEA 2000 network, making its role in a networked fuel-flow setup unusually clear. Buyers seeking that monitor-to-network link can assess it by function rather than relying on the product title alone.

The stated sensor-data interface role explains how this monitor fits into a system: it connects fuel flow sensor data with an NMEA 2000 network. The listed special feature also confirms NMEA 2000 compatibility, reinforcing that use case. The listing does not specify which sensors are compatible, how many can connect, or the installation process, so buyers should treat the network role as established but avoid assuming details about sensor selection or setup.

Skip it if you need a listed compatible sensor model or connection procedure before planning your system; neither is supplied here.

Choose this Maretron FFM100-01 when you need the explicitly stated link between fuel flow sensor data and an NMEA 2000 network. Confirm sensor selection and installation requirements separately, as the listing does not detail either.
