Abstract

---

An ultrasonic measurement apparatus (10) for measuring the flow velocity of a fluid is provided 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). In this respect the deflection unit (20, 26, 32) forms a loop.
