Abstract:
1. An ultrasound measurement apparatus ( 10 ) for measuring the flow speed of a fluid in a conduit ( 12 ) having a plurality of ultrasonic transducers ( 14 ) pairs of which span between them a plurality of main measurement paths and at least one diagnosis measurement path, and having an evaluation unit ( 24 ) which is made to calculate a respective individual measured value for the flow speed from transit times of ultrasound transmitted and received with and against the flow on each measurement path ( 16 , 18 ), to calculate individual measured values of the main measurement paths as a main measured value for the flow speed, to determine a measured diagnosis value from the at least one individual measured value of the diagnosis measured path and to compare the main measured value and the measured diagnosis value with one another, characterized in that at least some of the ultrasonic transducers (
