    摘要: A device for determining a predetermined fill level of a liquid in a container, with a sensor unit, comprising a unit capable of oscillating mechanically, a transmitter unit, and a receiver unit, which is electrically and mechanically coupled to the transmitter unit, and which transduces the oscillation of the unit capable of oscillating into an electrical receiving signal. An electronic unit, comprising a regulating unit, which regulates a phase difference that exists between the electrical transmission signal and electrical receiving signal to a determined value at which the unit capable of oscillating conducts oscillations at a resonant frequency, and which forms an oscillation circuit with the transmitter unit, receiving unit and the unit capable of oscillating. The electronic unit comprises a compensation path with a compensation unit, which for compensating additional signal components in the receiving signal, which results from the mechanical and/or electrical coupling between transmitter unit and receiver unit, at least intermittently produces a compensation signal from the transmission signal and supplies this compensation signal to the receiving signal. The compensation unit produces the compensation signal in a way such that the compensation signal is opposite to the additional signal components in the receiving signal.

An apparatus associated with the method is also disclosed.

The apparatus has at least one mechanically oscillatable unit unit which produces a measurement signal at least dependent on the process variable. It also has at least one electronic unit which evaluates the measurement signal, and at least one function test unit associated with the electronics unit. The measurement signal passes through the electronics unit on at least one processing path, and the function text unit operates on the processing path during a function test in such a manner that a test measurement signal results from the measurement signal received by the electronics unit. The test measurement signal corresponds essentially to the measurement signal, which occurs for a predetermined value of the process variable.
