Flow sensors keep motorsport moving

Morgan Advanced Materials and Sentronics have worked together to create a new fuel flow sensor which provides motorsport manufacturers with accuracies of ±0.25%, which is contributing to increased control over fuel consumption.

Designed to help promote energy efficiency in motorsport by measuring fuel flow as part of limiting total energy use, the fuel flow sensor is appropriate for all categories of motor racing, including touring and rally cars, as it can accurately measure flow rates of ±8,000ml per minute, across a temperature range of 0°C to 105°C. Weighing in at just 330g - far less than the 500g maximum weight permitted by the Fédération Internationale de l'Automobile (FIA) - the sensor is said to provide an exceptional degree of accuracy without adding unnecessary weight to the vehicle.

The fuel flow sensor is capable of operating in fluid pressures of 50kPa to 2,500 kPa and an external pressure rating of 300kPa, making it ideal for harsh vehicle applications. Intelligent on-board electronics process volumetric flow values and compute a mass flow output. Charles Dowling of Morgan explains: "Sensor functionality in motorsport is crucial, as teams risk disqualification if they cannot efficiently balance performance and fuel consumption. Morgan and Sentronics have worked together to turn this project around in only a few months, showcasing the responsiveness necessary to meet the tough demands of the motorsport industry.

"Sentronics have optimised the electronics around the sensor to create our most accurate readings to date - twice as sensitive as some mass flow meters available and at a much lower cost."

Manufactured from highly engineered materials including anodised aluminium alloy with stainless steel to form a compact and lightweight unit with no moving parts, the sensor is compatible with all fuel types.
