ABSTRACT:
Apparatus (1) for measuring the amount of a substance (2) in a vessel which comprises a detector means comprising at least two electrodes (3) adopted to generate an electric signal in response to contact of the electrodes with the surface of the substance (2), a first reference point (6) on the detector means which point is a fixed distance from the ends of the electrodes (3) said reference point being provided on a material suitable for reflecting waves from a wave transmitting-receiving device (8) e.g. a sonar device, preferably located in a fixed position above the first reference point for measuring the distance from the first reference point (6) to a second reference point (70) at the wave transmitting-receiving device (8) whereby the amount of the substance (2) in the vessel can be determined by computation, e.g. from knowledge of the height of the vessel to the fixed second reference point, determination of the height from the surface of the liquid to the second reference point and the cross sectional area of the vessel.
