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 measuring apparatus for measuring the flow rate of a fluid in a conduit having two measurement systems is provided that each have at least one pair of ultrasound transducers that span a measurement path between them and that each have a control unit to determine transit times from ultrasound transmitted and received with and against the flow. In this respect, the control units are each configured to fix measurement times for a transit time determination on a measurement path autonomously and independently of one another in accordance with a rule that produces a respective different sequence of the measurement times in both measurement systems.
