Abstract
An ultrasonic measuring device for measuring a fluid flowing in a pipe includes a housing and transducers. The housing receives and fixes the pipe, so that the fluid can flow through a central recess in a flow direction. The ultrasonic transducers emit and receive ultrasonic signals. Two first ultrasonic transducers are arranged laterally on a first side of the central recess, and two second ultrasonic transducers are arranged on a second side of the central recess. The second side is opposed to the first side, so that the recess is located between the first and the second ultrasonic transducers, and the ultrasonic transducers are arranged and aligned so that one of the first ultrasonic transducers emits a first measuring signal to one of the second ultrasonic transducers obliquely to the flow direction and receive a second measuring signal emitted by the second ultrasonic transducer obliquely to the flow direction.
