Abstract:
1. An ultrasonic measurement apparatus ( 10 ) for measuring the flow velocity of a fluid which flows in a pipeline in a main flow direction, wherein the ultrasonic measurement apparatus ( 10 ) has an ultrasonic measurement zone ( 36 ) with at least a pair of ultrasonic transducers ( 38 ), an evaluation unit for determining the flow velocity from a propagation time difference of ultrasound transmitted and received with and against the flow, as well as a deflection unit, by means of which the fluid from the main flow direction is deflectable and suppliable to the ultrasonic measurement zone ( 36 ), wherein the deflection unit ( 20 , 26 , 32 ) forms a loop having an inflow region ( 24 ) and an outflow region ( 28 ), wherein the ultrasonic measurement zone ( 36 ) is provided in the outflow region so that the flow is reproducibly stabilized on entry into the ultrasonic measurement zone ( 36 ) such that transmitted and received ultrasound have at least one component in a direction transverse to the flow.
