Verfahren zur Überwachung des Betriebszustandes eines Ultraschallwandlers in einem Ultraschall-Durchflussmessgerät |
摘要 |
<p>A method for monitoring the operating state of a first ultrasonic transducer in an ultrasonic, flow measuring device having at least one measuring tube and at least two ultrasonic transducers, including steps as follows: a) providing a first value or a plurality of first values, which relate to the geometric arrangement of the first ultrasonic transducer in the measuring tube and/or to the geometric arrangement of the first ultrasonic transducer relative to a second ultrasonic transducer; b) ascertaining a second value or a plurality of second values for a flow velocity of a medium located in the measuring tube c) providing a third value and/or a plurality of third values for temperature and/or pressure of the medium located in the measuring tube; d) simulating a desired value of a signal strength taking into consideration the first, second and/or third values; and e) comparing the simulated desired value of a signal strength with an ascertained real value of the signal strength.</p> |
