An apparatus for determining a physical process variable of a medium (2) which can be used in conjunction with various sensor types, the sensors having in common that they determine a process variable by means of a delay-time method. The apparatus has a sensor (4), a sensor-specific application unit (5) and an evaluation unit (6), which is essentially independent of the sensor type used, the sensor (4) being assigned a transmitting/receiving unit (7), the transmitting unit (7a) transmitting measuring signals in the direction of the medium (2) and the receiving unit (7b) receiving the measuring signals influenced by the interaction with the medium (2), and the application unit (5) being designed in such a way that it provides measurement data, independently of the type of sensor (4) used, from which the evaluation unit (6) determines the physical process variable using a delay-time method by means of a uniform evaluation algorithm.

[ We claim:] [1.]1. An apparatus for determining a physical process variable of a medium comprising:a sensor of a sensor type having a transmitting unit which transmits measuring signals in the direction of the medium and a receiving unit which receives echo measuring signals influenced by the interaction with the medium;an application unit which is dependent on the sensor type of the sensor, the application unit accepting the echo measuring signals and providing measurement data, the measurement data being independent of the sensor type of the sensor, andan evaluation unit which is substantially independent of the sensor type of the sensor, the evaluation unit accepting the measurement data and determining the physical process variable using a delay-time method.
