Maretron Fuel Flow Sensor - 25-500 LPH/6.6-132 GPH

The Maretron Fuel Flow Sensor (M2AR) is a precision marine monitoring instrument designed for anglers and boaters who demand real-time fuel consumption data on the water. Whether you're running a full day offshore, navigating inland waterways, or managing fuel costs on extended trips, this sensor integrates seamlessly into your boat's fuel system to track exactly how much fuel your engine is burning. Accurate fuel flow monitoring helps you optimize engine performance, plan longer runs between fill-ups, and identify mechanical issues before they become costly problems.

This Maretron unit measures fuel consumption across a wide operating range of 25 to 500 liters per hour (6.6 to 132 gallons per hour), making it suitable for everything from modest outboard setups to powerful inboard and twin-engine configurations. The sensor connects via a 1/4" NPT female port and includes a 1-meter cable for flexible installation along your fuel line, allowing you to position the unit where it best integrates with your existing plumbing. Engineered to withstand marine environments, the M2AR operates reliably from -40°F to 176°F, with extended storage tolerance to -85°F, ensuring dependable performance whether you're fishing arctic waters or tropical flats.

Professional captains, serious recreational anglers, and commercial fishing operators rely on Maretron fuel flow sensors to feed data into networked marine electronics systems—compatible with NMEA 0183 and NMEA 2000 networks—giving you actionable fuel economy data on your plotter or dedicated gauge. Installation is straightforward for anyone with basic fuel system knowledge; the sensor threads directly into your fuel line with minimal modifications. This is particularly valuable for tournament anglers tracking fuel burn rates, liveaboard cruisers managing consumption on extended voyages, or any boater looking to maximize efficiency and reduce operational costs.
