Ultrasonic probe is used to measure fuel level in tanks of diesel vehicles and machines. It is used in fuel consumption monitoring systems, and it is very simple and safe to use. For measurement, probe uses properties of ultrasound. It emits an ultrasonic wave into interior of tank, and then receives echo signal. Level in tank is determined by analyzing time after which echo returns from fuel surface.

Pressure probe
Pressure probe is designed to measure fuel in tanks of motor vehicles, working machines and locomotives. Probes are approved by Ministry of Transport. Fuel level is measured by comparing height of liquid column and resulting from it, hydrostatic pressure. Probe consists of two parts: sensing part in a steel tube and an electronic part in aluminum housing that can be sealed. Measuring element is a piezoresistive sensor separated from medium by diaphragm. Pressure is measured at diaphragm level of immersed probe (5mm above tank bottom). Depending on type of tank (non-pressurized or pressurized), pressure measurement is related to atmospheric pressure or pressure inside tank.
