Abstract: A flow meter for measuring the flow rate of a flowing medium has a plastic measurement tube for routing the medium and a connecting device for connecting an end of the measurement tube to an end of a plastic pipeline. So that measurement tube of plastic can be connected easily and to the plastic pipeline, the connecting device is formed by a heating means that is integrated into an inner wall of the end of the measurement tube and that melts at least the end of the measurement tube to thereby form a melted connection between the measurement tube and the pipeline.

Abstract: A magnetoinductive flowmeter for measuring the flow rate of a moving medium includes a measuring tube conducting the medium, and an insert provided in the measuring tube. The insert consists of at least one first part and one second part which first part is introduced into the measuring tube from one end of the measuring tube while the second part, introduced into the measuring tube from the other end of the measuring tube, is joined with the first part in leak-proof fashion. The result is an easy-to-install insert that ensures secure and maintainable retention.

Abstract: A magnetoinductive flowmeter incorporates an electromagnetic circuit with at least one coil and a minimum of two detachably interconnected components of a magnetic material. One of the components features a resiliently deformable spring section that presses against the other component. The result is an easy-to-assemble magnetoinductive flowmeter that can be manufactured with substantial production tolerances.

Abstract: Ultrasonic flow meter of the clamp-on type for the measurement of the flow rate of a liquid in a pipeline, provided with two piezoelectric transmitting-receiving transducers, each accommodated in a housing, which are clamped at both sides of the pipeline axially offset with respect to each other thereon and which alternately transmit ultrasonic pulses into the pipeline and receive them therefrom in order to determine the flow rate from the transit time of the source pulses in the upstream and downstream direction. The transducers each consist of a row of adjacent subtransducers, the pulse emission face of which row is coupled over its entire length in the axial direction to the pipe wall.
