This season Formula One battle will go from 2.4 V8 engine to 1.6 V6 turbocharged engines. But this is not all: between the various new limits that will come to contain the power and fuel consumption, are also those related to the absolute maximum turbo pressure of 4 bar, the tank capacity limited to 100 kg of fuel and finally the flow max with which the fuel itself will go to supply the motor, established in 100 kg / h.
According to some F1 engineers, in fact, just this last parameter will be the real obstacle to the “free expression “of the new turbo engines. Waiting to see if it is really so, it is nevertheless clear that the ongoing monitoring of this measure will be pretty basic.
For this use an ultrasonic sensor will be used specially made from Gill Sensors, a British firm which specialized in various kinds of sensors, including those for the flow of various liquids (including fuel) and the data acquisition board telemetry from the car race. Their sensor has just been approved by the FIA.
Designed with an innovative, lightweight construction, the flow meter achieves the rapid transit response rate vital for the harsh environment application. The meter is capable of a flow measurement rate of 8000ml/min and fulfils the FIA’s accuracy requirements.
“Gill Sensors are thrilled to have been chosen to undertake this extraordinary venture and we are delighted that the FIA is confident in the performance and durability of the Ultrasonic Fuel Flow Meter.” says Mike Gill, Chairman of the Gill Group. “We would like to thank the FIA and all the teams for their backing which has been fundamental to the project.”
The ultrasonic fuel flow meter will remain homologated for use within Formula 1 and WEC throughout the expected lifetime of the turbocharged V6 engine and future designs.
