Ultrasonic clamp-on mass flow meter

摘要

Device for determining and/or monitoring the volume or mass flow of a medium (4) comprises an ultrasound sensor (2) with a sound-generating element (5) and an advancing body (6), a first adjusting mechanism (7) for adjusting the incident angle/emitting angle and a regulating/evaluating unit which measures the medium in a line (3). Preferred Features: The adjusting mechanism automatically and/or manually adjusts the incident angle/emitting angle of the ultrasound sensor. The adjusting mechanism converts a linear movement into a defined rotary movement of the sound-generating element.
