Gill Sensors has developed a new Ultrasonic Fuel Flow Sensor, which has been designed specifically for use on a race car. The new sensor is lightweight, compact and robust, designed to withstand the extreme levels of vibration experienced in this type of installation.
The sensor uses Gill’s proven ultrasonic measurement technology to detect bi-directional fuel flow rate to 0.25% accuracy in real time, marking a major step forward from the impellor flow devices often used in racing applications.
This technology has a number of major advantages over impellor flow sensors, the most significant of which is the removal of mechanical parts from the flow path. This ensures minimal pressure drop across the sensor, providing true flow rate data with little impact on the flow itself. The removal of mechanical moving parts and bearings also eliminates mechanical dampening and allows much higher temporal resolution and accuracy for the capture and measurement of high frequency pulsating flows.
The detail provided within the flow data allows engineers to fully analyse fuel flow characteristics, with the sensor’s high level of sensitivity allowing even the pulses of fuel injectors to be identified at low RPM ranges.
The Ultrasonic Fuel Flow Sensor has been designed for use with all race fuels, including aggressive ethanol blends, and is capable of accurately recording flow rate from 0.5ml/min to 3000ml/min. With no moving parts to jam, break or wear out, the sensor provides extremely reliable operation even in the harshest of operating environments.
The sensor features a newly-developed electronic platform, which integrates the latest FPGA technology capable of measuring flow rate up to 4000 times a second. In addition to a digital output, a 0-5V analogue output is provided across the calibrated flow range.
As focus within top level Motorsport moves towards fuel efficiency, accurate monitoring of fuel usage is rapidly becoming an essential element of most telemetry systems. The Gill Fuel Flow Sensor has been designed specifically to address these requirements, providing governing bodies, race teams and engine developers alike with a means of accurately monitoring fuel flow and usage in real time.
Gill Sensors will launch and demonstrate the new Ultrasonic Fuel Flow Sensor on stand 5090at Professional Motorsport World Expo, which takes place in Cologne, Germany from 15th to 17th November 2011.
