Description

Technical Field

[0001] The utility model relates to the technical field of instruments and meters, in particular to a probe installation device for an ultrasonic flow meter. Background Art

[0002] The ultrasonic flowmeter, equipped with an ultrasonic sensor mounted on the outer wall of a field pipeline, converts the volumetric flow rate of the liquid flowing through the pipeline into a standard current signal and accumulated pulse signals. As the primary instrument for on-site water flow measurement, it transmits the standard current signal via a 232 cable to a paperless recorder, computer, or PLC, enabling flow measurement and automated production control.

[0003] When an ultrasonic beam propagates through a liquid, the flow of the liquid causes a slight change in the propagation time, which is proportional to the flow rate. At zero flow, the time required for both sensors to transmit and receive the sound wave is exactly the same (the only technology that can actually measure zero flow). When the liquid is flowing, the propagation time of the sound wave upstream is longer than that of the sound wave downstream. Common ultrasonic sensors come in two types: externally mounted, attached to the outer wall of the pipe for measurement; and inserted, requiring a welded opening in the pipe for installation, with the sensor in direct contact with the liquid being measured.

[0004] Ultrasonic flowmeters, a common instrument for measuring liquid flow, are widely used within Benxi Steel's plant, serving as primary, secondary, and tertiary liquid energy medium settlements between various factories and mines. On-site metering process requirements necessitate continuous and stable metering. However, due to the age of some on-site pipelines, which are severely scaled and made of ductile iron, external ultrasonic sensors are unable to function properly. Insertable ultrasonic sensors cannot be welded and installed on ductile iron pipelines. This results in the inability to measure some of the older cast iron pipelines, resulting in metering discrepancies and a serious impact on Benxi Steel's cost-benefit calculations per ton of steel. Utility Model Content

[0005] The utility model provides a probe installation device for an ultrasonic flowmeter, which solves the problem that the existing ductile iron pipe cannot be welded.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for installing an insertion probe of an ultrasonic flowmeter comprises two pipe clips installed on the outer wall of a measured pipe, wherein bolt connection plates are provided at both ends of the pipe clips, and the two pipe clips are connected via the bolt connection plates. An ultrasonic insertion sensor installation hole is provided on one of the pipe clips, and a sensor base is welded under the installation hole.

[0008] Further, bolt holes are provided on the bolt connection plate, and bolts respectively pass through the bolt holes on the bolt connection plate to fix the two pipeline fasteners.

[0009] Further, through holes are provided on the pipeline to be measured, and the positions of the through holes correspond to the positions of the mounting holes of the ultrasonic insertion sensor.

[0010] Further, after the ultrasonic insertion sensor is inserted into the mounting hole and the through hole, it is placed on the sensor base.

[0011] Further, the ultrasonic insertion sensor is connected to a signal cable.

[0012] Further, a plurality of insertion probe mounting devices for ultrasonic flowmeters are installed on the same pipeline to be measured.

[0013] The beneficial effects of the present utility model are as follows:

[0014] After the fasteners are installed in the present utility model, the ultrasonic flowmeter insertion sensor realizes the installation of the ductile iron pipeline, overcomes the problem that the ductile iron pipeline cannot be measured due to serious internal wall scaling, ensures that the ultrasonic flowmeter can achieve measurement in a wider range of areas, and at the same time solves the problem of the measurement vector of some liquid media in the Benxi Iron and Steel Group, ensuring the normal operation of the liquid energy media measurement work at the first, second, and third levels of the Benxi Iron and Steel Group.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present utility model. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be clear that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the authorized specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present utility model, it should be understood that orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. generally indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the scope of protection of the present utility model: the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0024] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.
