摘要： A method for operating a Coriolis mass flow rate meter and a Coriolis mass flow rate meter including an evaluation device, a measuring tube having a medium flowing therethrough and which is excited so as to perform oscillations, and at least two spaced oscillation pickups spaced apart in the longitudinal direction of the measuring tube to each generate an oscillation signal, wherein a first indicator variable based on the damping of the oscillations of the measuring tube is initially used to detect deposits in the measuring tube and if, based on the first indicator variable, increased damping is established, a second indicator variable is used, which is based on the manifestation of harmonics in the frequency spectrum of an oscillation signal such that reliable detection of deposits and therefore an indication of the state of meters and pipelines in a process engineering installation are advantageously possible.

摘要： An acoustic pick-up, particularly an ultrasonic pick-up for acoustically diagnosing machines, for example, for detecting leakage in valves or for diagnosing positions, comprising a piezoelectric measuring element and an electronic circuit that processes the measurement signal into a form that is suited for transmission to an evaluation device. In order that the acoustic pick-up can function without an external auxiliary power supply, means are provided by means of which auxiliary power required for operating the electronic circuit can be generated from the acoustic signal to be picked up.

摘要： A diagnostic system, for a valve (2), having a sensor (12) that senses structure-borne noise and having a device (14) for evaluating a measurement signal (13) of the structure-borne noise. During a calibration process, a first progression of the measurement signal is sensed for the closed position of the valve (2) and a first value (w1) of a characteristic is determined. To simulate leakage noise, the valve (2) is nearly closed during operation, a second progression of the measurement signal is sensed and a second value (w2) is determined. If the deviation of the second value from the first value is sufficiently large, a diagnosis is possible. A third progression of the measurement signal is sensed for the closed position of the valve as in an installed condition, and a third value (w3) is determined. If the deviation of the third value (w3) from the first value (w1) is too great, and if a diagnosis has been identified as being possible, then the system deduces that the valve leaks.

摘要： A diagnostic system and method for a valve, especially a check valve of a positive displacement pump, including at least one solid-borne sound sensor is provided. A first value of a parameter of a sound signal recorded in the closed state of the valve and a second value of a parameter of a sound signal recorded in the open state of a valve are determined essentially. A signal indicating a disturbance is issued if the deviation between the first value and the second value exceeds a predefined threshold value, resulting in particularly good insensitivity.
