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

A measurement apparatus () and to a method provide for the determination of a flow rate (v) and/or of a throughflow (Q) of a fluid () flowing in a conduit (). At least one first ultrasonic transducer () and one second ultrasonic transducer () permit a flow rate determination via the time of flight of an ultrasound signal. To further improve the determination of a flow rate of a fluid using ultrasonic transducers, in particular at very high flow rates, and to enable the measurement of very high flow rates, a noise-measuring ultrasonic transducer () is provided that measures the noise generated in on the flowing past of the fluid () in the ultrasonic transducer, and a control and evaluation device () is configured to determine the flow rate (v) using the noise measurements.
