Frequently Asked Questions
Why choose a capacitive fuel sensor over ultrasonic?
Capacitive probes sit in the fuel and hold 99.5% accuracy with slosh and temperature compensation. Ultrasonic mounts outside the tank and is easier to fit, but is the lower-precision option.
Will a capacitive sensor work on a sloped site?
A standard capacitive probe still reads level; for construction and mining tanks on slopes, pair it with SP BLE 4 tilt compensation.
How small a theft can it detect?
TrackAlways capacitive deployments detect level changes down to 0.5 litres when calibrated on Venus.
Does installation require draining the tank?
In-tank probes need a calibrated hole and sealing. TrackAlways installers handle this at the yard; downtime is typically a few hours per truck, not a multi-day workshop stay.
