Clamp-on ultrasonic flow meter for measuring mass flow rates in pipes or conduits, uses evaluation and control unit to optimize transducer positions based on comparison of a measurement value with a reference value

摘要

The flow meter comprises two ultrasonic transducers (2, 3) attached in an adjustable manner with a positioning unit to the container. An evaluation and control unit (8) optimizes the position of the transducers based on comparison of an set value with an actual measured value. A display unit (12) indicates to an operator the direction in which a position change must be made.
