Description

Ultrasonic flowmeter
Technical field:
The utility model relates to the field of measuring techniques of flow, specifically a kind of ultrasonic flowmeter.
Background technology:
As everyone knows; tradition flowmeter or heat energy table adopt the vane type flow sensor more; the number of turns of wheel rotation is directly proportional with flow; counter is by gathering the number of turns calculated flow rate of wheel rotation; because there is mechanical wear in the rotation of impeller; therefore there are defectives such as complex structure, serviceable life be short in traditional flowmeter or heat energy table; its measuring accuracy reduces after using the long period; in addition; because there is the situation that contains impurity in fluid; flowmeter or heat energy table usually can be subjected to stopping up etc. and have a strong impact on, and bring loss to the user.
Ultrasonic flow meter can overcome the shortcoming of above-mentioned vane-wheel type flowmeter fully owing to there is not mechanical movable part.At present, the ultrasonic flowmeter that people use comprises table body, ultrasonic transducer and installing component and counter, and wherein measuring channel is a circular pipe.The ratio that accounts for whole circular measuring channel cross section owing to the efficiently sampling cross section of ultrasonic transducer in circular measuring channel is less, the homogeneity of measuring channel flow field has a significant impact measuring accuracy, therefore for guaranteeing measuring accuracy, pipe laying structure and straight pipeline length all there is higher requirement.
Summary of the invention:
The purpose of this utility model is to improve the deficiencies in the prior art, it is more that the efficiently sampling cross section of ultrasonic transducer accounts for the ratio in whole measuring channel cross section in the flat pipeline, improve measuring accuracy, strengthen antijamming capability, in the requirement that guarantees to reduce under the identical measuring accuracy condition to pipe laying structure and flow development length.

A kind of ultrasonic flowmeter, comprise table body, ultrasonic transducer and installing component and counter, wherein show body and comprise table body pipe, table body flange, table body mount pad, installing component comprises locating ring, clamp nut and seals plug screw and seal, it is characterized in that showing the pipeline that the body center section is used to measure flow is the flat pipeline, table body porch is provided with cowling panel, and ultrasonic transducer is installed in leptoprosopy place, flat flow measurement pipeline both sides respectively in pairs.
The cross section of flat flow measurement pipeline is rectangle or the rectangle of chamfering is arranged in the utility model, because measuring channel reduced cross-sectional area, the ratio that the efficiently sampling cross section of ultrasonic transducer accounts for whole measuring channel cross section increases, the measuring amount of ultrasonic transducer convection cell increases, and then raising measuring accuracy, strengthen antijamming capability, improve measurement stability, in the requirement that guarantees to reduce under the identical measuring accuracy condition to pipe laying structure and flow development length.
The utility model table body porch is provided with cowling panel, and cowling panel is tabular, is positioned at middle part, table body porch, and cowling panel is fixedlyed connected with the inwall of table body, can carry out rectification to the fluid of measuring better, improves the homogeneity of table body flow field.
The paired ultrasonic transducer of the utility model is by heart position being installed in leptoprosopy place, flat flow measurement pipeline both sides respectively, the central axes of ultrasonic transducer, perhaps in pairs ultrasonic transducer is installed in leptoprosopy place, flat flow measurement pipeline both sides respectively by parallel position, and wherein a ultrasonic transducer sends signal and received by another ultrasonic transducer after mirror reflects.Ultrasonic transducer is through seal, locating ring, clamp nut and seal plug screw and be assemblied in the table body mount pad, prevents that fluid from leaking at table body mount pad place, guarantees well-equipped running.
The beneficial effects of the utility model are that the pipeline that table body center section is used to measure flow adopts flat pipeline and table body porch that cowling panel is set, fluid in the pipeline is played good rectified action, improve the homogeneity in the flow field in the table body pipe, improve measuring accuracy, strengthen antijamming capability, improve measurement stability, in the requirement that guarantees to reduce under the identical measuring accuracy condition to pipe laying structure and flow development length.
