Abstract
A flow rate assembly can include a housing having a measurement channel extending along the housing axis and through a portion of the housing between the first and second ends of the housing, an outer cup portion positioned at least partly within the housing, and a transducer positioned within the outer cup portion and sealed from fluid flow past the outer cup portion, the transducer having a width perpendicular to the housing axis and greater than the width of the measurement channel, the transducer configured to generate an ultrasonic signal and to direct the ultrasonic signal through the measurement channel.
Claims13
A flow rate assembly comprising:
- a housing having:
- a housing axis;
- a first end having an inlet positioned along the housing axis;
- a second end having an outlet positioned along the housing axis;
- and
- a measurement channel extending along the housing axis and through a portion of the housing between the first and second ends of the housing, the measurement channel having a width perpendicular to the housing axis;
- a first outer cup portion positioned at least partly within the housing, the first outer cup portion comprising:
- a head portion connected to a wall of the housing;
- an elongate portion connected to the head portion, the elongate portion having a first face facing the measurement channel;
- and
- a plurality of flow channels through the head portion configured to permit fluid to flow past the first outer cup portion through the plurality of flow channels, each of the plurality of flow channels of the first outer cup portion having an end facing an end of another of the plurality of flow channels, so that a boundary wall is formed between facing ends, each boundary wall positioned symmetrical to another boundary wall relative to the housing axis;
- and
- a first transducer positioned along the housing axis and within the elongate portion, the first transducer sealed from fluid flow past the first outer cup portion, the first transducer having a width perpendicular to the housing axis and greater than the width of the measurement channel, the first transducer configured to generate an ultrasonic signal and to direct the ultrasonic signal through the measurement channel;
- wherein the first and second ends of the housing are configured to mate with an open pipe end in an in-line manner.
A flow rate assembly comprising:
- a housing having:
- a housing axis;
- a first end having an inlet positioned along the housing axis;
- a second end having an outlet positioned along the housing axis;
- a measurement channel extending along the housing axis and through a portion of the housing between the first and second ends of the housing, the measurement channel having a width perpendicular to the housing axis;
- and
- a first housing chamber between the measurement channel and the inlet, as measured along the housing axis, the first housing chamber having a tapered inner wall;
- a first outer cup portion positioned at least partly within the first housing chamber, the first outer cup portion comprising:
- a head portion connected to a wall of the housing;
- an elongate portion connected to the head portion, the elongate portion having a tapered portion between a first face and the inlet and the measurement channel;
- and
- at least one flow channel through the head portion configured to permit fluid to flow past the first outer cup portion through the at least one flow channel;
- and
- a transducer positioned along the housing axis and within the elongate portion, the transducer sealed from fluid flow past the first outer cup portion, the transducer having a width perpendicular to the housing axis and greater than the width of the measurement channel, the transducer configured to generate an ultrasonic signal and to direct the ultrasonic signal through the measurement channel;
- wherein the housing comprises a first housing, a second housing, and a third housing, the third housing positioned between the first housing and the second housing, the flow rate assembly comprising at least one circuit board mounted within a housing interior formed between the first housing and the third housing.
