An inspection device for an ultrasound flow meter is provided that has an inspection chamber having a fluid at a flow velocity of zero and having a first installation station for a first ultrasonic transducer and having a second installation station for a second ultrasonic transducer of the ultrasound flow meter so that the ultrasonic transducers are aligned toward one another in the installed state and span an ultrasound measurement path through the inspection chamber on the connection line. The invention further relates to a method of inspecting and/or calibrating an ultrasound flow meter.

Inspecting an ultrasound flow meter

An ultrasound flow measurement apparatus () for determining the flow rate of a fluid flowing in a line () is provided having at least one measurement path () at which a first ultrasonic transducer () and a second ultrasonic transducer () are arranged opposite one another with the flowing fluid between them, and having an evaluation unit that is configured to calculate the flow rate from a time of flight difference of ultrasonic pulses along the measurement path () in the direction with the flow () and against the flow (). The ultrasonic transducers (-) here are positioned such that a specific part pulse is isolated in time in a received signal of the respective receiving ultrasonic transducer (-), with the part pulse corresponding to a direct sound, a reflected sound, an axially broken fluid sound, or an azimuthally broken fluid sound.

Ultrasound flow measurement apparatus and method for determining the flow rate

An ultrasound flow measurement apparatus is provided having a plurality of ultrasonic transducers for determining the flow rate of a fluid flowing in a line, said ultrasound flow measurement apparatus having a plurality of measurement paths at which two respective ones of the ultrasonic transducers are arranged opposite one another with the flow being arranged therebetween and with a mutual axial spacing in the longitudinal direction of the line and having an evaluation unit that is configured to calculate the flow rate from time of flight differences of ultrasonic signals along the respective measurement paths in the direction with the flow and against the flow. The measurement paths have different axial offsets here.
