Maretron M1AR Fuel Flow Sensor 0.53 To 26.4 GPH

The Maretron M1AR Fuel Flow Sensor is a precision marine fuel management instrument engineered for vessels requiring real-time fuel consumption monitoring across a wide operational envelope. Designed for tactical and maritime applications where fuel efficiency directly impacts mission duration and operational range, this sensor bridges the gap between legacy analog systems and modern digital fleet management. Users operating commercial fishing vessels, patrol boats, military craft, and high-performance watercraft depend on accurate fuel flow data to optimize route planning, detect system anomalies, and maintain strict operational budgets.

The M1AR operates across a measurement range of 0.53 to 26.4 gallons per hour, making it suitable for both low-displacement auxiliary systems and high-output primary propulsion plants. This wide dynamic range eliminates the need for multiple sensors across different engine configurations. The sensor employs turbine-based flow measurement technology that translates mechanical rotation into digital signals compatible with Maretron's N2K digital backbone and legacy analog displays. Its robust construction withstands saltwater corrosion, vibration, and thermal cycling inherent to marine environments, while the compact form factor permits installation in tight engine compartments without compromising accessibility for routine maintenance.

Fleet operators, naval technicians, and marine engineering teams benefit most from integrating the M1AR into comprehensive fuel management systems that track consumption patterns, alert to fuel line leaks, and validate engine efficiency metrics. Installation requires integration with Maretron's digital network infrastructure or compatible NMEA 0183/0184 systems; consult your vessel's fuel system documentation to confirm port compatibility and fuel type certification. The 2 lb weight and streamlined profile allow straightforward retrofitting on existing vessels or incorporation into new-build specifications without structural reinforcement.
