Number for a kind of entitled " New Large Caliber ultrasonic calorimeter " disclosed in 201520024896.7 utility model, its structure
For the pipeline coupling flange at housing two ends, multi-use counter connecting seat, the multi-use counter connecting seat are snapped with its housing
The left and right sides be respectively provided with a transducer installing hole, a ultrasonic transducer group is installed in described each transducer installing hole
Part, transducer installation site needs or design factor itself because of the machining for inclining aperture, in order to ensure that transducer is installed
The device of the machining of hole post conveniently and after its installation does not affect the installation of instrument flange plate bolt, transducer position to set
Meter leaves instrument ring flange certain distance, the effect level projector distance being so considerably reduced between transducer.And, transducing
Device installation site from flange inner side more away from line is bigger with the angle of level between its transducer, projector distance is also shorter,
Between the measuring accuracy of ultrasonic flowmeter and the range ratio parameter of effusion meter and two transducer faces line with
The distance of instrumentation pipeline floor projection is proportional, that is to say, that in a pair of transducer transmittings, receive ultrasound wave arrival most
In the case of little energy energy normal work, the floor projection distance between two transducers is longer, and the sound path of ultrasound wave is also longer；Sound
The performance parameter of flow accuracy, the range ratio that Cheng Yuechang, time difference computing module or effusion meter can be calculated etc. is better.
In the prior art, transducer installation site because the machining for inclining aperture need or design factor itself and
Be afraid of to affect the reasons such as instrument flange bolt installation, cannot all abut flange design, so be considerably reduced having between transducer
Effect floor projection distance.And, transducer installation site from flange inner side more away between its transducer line and level angle just
Bigger, projector distance is also shorter, and the index parameter of the measurement of ultrasonic flowmeter is also poorer.
Utility model content
In view of the above-mentioned state of the art, technical problem to be solved in the utility model is to provide a kind of degree of accuracy
The sound path expansion structure of the heavy caliber ultrasonic flowmeter high with range ratio.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：Including flow meter tube, installed in stream
The flange at gauge body two ends, the flange is provided with screw, and the screw is provided with nut, and the flange includes first flange and second
Flange, the flow meter tube two ends top is symmetrically arranged with two hole posts, and the hole post includes the first hole post and the second hole post,
The first hole post edge sets against first flange inner side, the second hole post edge against second flange inner side, the hole post
Put between nut and flow meter tube outer wall, flow meter tube middle part top arranges fixed seat, installs in the fixed seat
There is flowmeter electronics box, transducer assemblies are installed in the hole post, the transducer assemblies are by cable and flowmeter electronics box
Electrical connection.
Further, the hole post side arranges through hole, and the through hole is connected by pipeline with fixed seat.
Further, the transducer assemblies include the first ultrasonic transducer and the second ultrasonic transducer, described the
One ultrasonic transducer is installed in the first hole post, and second ultrasonic transducer is installed in the second hole post.
Further, the flow meter tube nominal diameter is DN50～DN300mm.
Further, when the flow meter tube nominal diameter is DN125mm, first ultrasonic transducer and second
Between ultrasonic transducer surface is 161mm to penetrating spacing with the projector distance of level.
Compared with prior art, the utility model has the advantage of：This utility model is by against flange and parallel to method
Orchid arranges hole post so that the installation of transducer can successfully avoid the position that flange installs nut so that a pair of ultrasonic wave transducers
Line between device is minimum with horizontal sextant angle, effect level projector distance is most long, is surveyed according to the effusion meter instrument of different bores, its
Floor projection distance between projector distance heavy caliber flowing meter transducer more equal than existing correspondence extends 30～60%, due to sound path
Lengthening, reach degree of accuracy that effusion meter is significantly increased and range ratio this utility model be reasonable in design, accord with the demands of the market,
It is adapted to promote.
