Microlight Fuel Gauge

Microlight Fuel Gauge
Microlight Fuel Gauge
The design of this measuring instrument was based on thse requirements:
- a microlight always takes off with the fuel tank full; – fuel consumption is usually between 7 and 9 litres/hour; – it’s important for the gauge to be perfectly readable in all circumstances, e.g. in the form of a bargraph; – an indication of the amount of fuel remaining, expressed in litres;– an indication of the instantaneous fuel consumption (l/h); – it must be possible to have complete confidence in the gauge, so provision needs to be made for a warning in the event of it going wrong; All requirements are catered for by the present design.
