Abstract
The invention relates to an ultrasonic flow meter housing and to an ultrasonic flow meter comprising a housing. The housing is a monolithic polymer structure being cast in one piece. The monolithic structure includes a straight flow tube and a cavity separated from the flow tube, where a shared wall part forms part of the wall of the flow tube and of an inside surface of the cavity. The cavity is arranged for housing at least one ultrasonic transducer at the shared wall part, and a measurement circuit operationally connected to the at least one ultrasonic transducer. In an embodiment, the cavity only has a single opening which can be sealed off by a cover.
Claims15
An ultrasonic flow meter housing comprising:
- a monolithic polymer structure being cast in one piece, the monolithic structure includes a flow tube and a cavity separated from the flow tube, wherein the flow tube defines a through-going straight flow section arranged for passage of a fluid between an inlet and an outlet, wherein a part of a wall of the flow section is part of an inside surface of the cavity, so that the flow section and the cavity has a shared wall area;
- and
- wherein the cavity is arranged for housing
- at least one ultrasonic transducer, at the shared wall area;
- and
- a measurement circuit operationally connected to the at least one ultrasonic transducer so as to allow measurement of a flow rate of the fluid.
