Review: Herrington Fuel-Overfill Alert System
October 3, 2013
The Overfill Alert System from Herrington Marine Technologies integrates with existing fuel tank sending units to alert the user when to halt the flow of fuel. An indicator light and audible buzzer activate when the fuel level reaches 95% capacity, allowing for 5% expansion within the tank itself. Once activated, the system automatically resets within 10 seconds.
The Overfill Alert System is ignition-protected and compatible with SAE standard sending units. Its design ensures no electronic feedback with onboard systems and is voltage surge protected through 48V DC. The 12V unit complies with ABYC/NMMA standards, and its sealed, flame-retardant ABS enclosure bears a flame rating of UL94.
Each unit includes a sunlight-visible 2 1/4″ W x 1 3/4″ H deck plate with LED indicator light, audible buzzer and ON/OFF illuminated dash power switch. The Overfill Alert System measures 4″ L x 2″ W x 1″ H.
