[0002] A single-flange pressure level transmitter is a type of transmitter. Based on the principle of pressure sensing, it calculates the current liquid level by measuring the change in pressure of the liquid density gauge. In industrial production processes, accurate measurement of pressure and liquid level is crucial for ensuring production safety and product quality.

[0003] For example, Chinese patent CN211954325U discloses an intelligent single-flange pressure level transmitter, which includes a connecting shell, a combination frame, a housing, a dial, a controller, and a frequency converter.

[0004] Existing single-flange pressure and level transmitters have many problems during use. They need to be connected to the container of the measured medium. Particulate impurities in the measured medium can clog the pressure tap of the pressure sensing unit, affecting the measurement accuracy and, in severe cases, causing measurement failure. To address these issues, an intelligent single-flange pressure and level transmitter is proposed. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5 As shown, this utility model provides an intelligent single-flange pressure and level transmitter, including a transmitter assembly 1. The transmitter assembly 1 includes a solid base 12 and a housing 13. A single flange 2 is provided at one end of the solid base 12. A filter assembly 3 is fixedly installed between the solid base 12 and the single flange 2. The filter assembly 3 includes a fixing plate 31, a sliding plate 37, and a filter plate 312. A groove 36 is formed on the top of the fixing plate 31. The two sides of the sliding plate 37 are slidably connected to the inner side of the groove 36. The filter plate 312 is disposed on one side of the sliding plate 37, and a through-hole is formed on the other side of the sliding plate 37. A filter screen 314 is fixedly connected to one side of the filter plate 312 through hole 39, and a symmetrical insertion hole 315 is opened at the top of the other side of the filter plate 312. A fixing rod 311 is fixedly connected to the top of the side of the slide plate 37 facing the filter plate 312. A threaded ring 316 is rotatably connected to one end of the fixing rod 311, and a threaded insertion rod 317 is threadedly connected to the inner side of the threaded ring 316. One end of the threaded insertion rod 317 is inserted into the insertion hole 315. The outer edge of the top of the slide plate 37 fits against the inner side of the groove 36. A sealing rubber ring 38 is fixedly connected to the outer edge of the top of the groove 36.

[0025] The specific setup and function of this embodiment are described below: This device adds a filter assembly 3 between the solid base 12 of the transmitter assembly 1 and the single flange 2. During installation, the filter assembly 3 is first moved along the slide groove 310 by sliding the sliders 313 at the four corners of the filter plate 312 until one side of the filter plate 312 is completely in contact with the slide plate 37. Then, the threaded ring 316 is rotated so that its axis is aligned with the axis of the insertion hole 315. Next, the threaded rod 317 is rotated until one end of the threaded rod 317 is inserted and fixed into the insertion hole 315, thus fixing the filter plate 312 to one side of the slide plate 37. The slide plate 37 is then placed on top of the fixing plate 31, and slides down the groove 36 until the bottom of the slide plate 37 is in contact with the bottom wall of the groove 36. A sealing rubber ring 38 is provided at the top edge of the groove 36. After the slide plate 37 is placed in the groove 36, the sealing rubber ring 38 can fill the gap between the slide plate 37 and the top of the groove 36. The sealing rubber ring 38 is made of polytetrafluoroethylene or rubber. The sealing rubber ring 38 has good elasticity and sealing performance, which improves the sealing performance of the slide plate 37 and the fixed plate 31 after installation, further enhances the sealing performance of the connection, and prevents media leakage. Finally, the mounting plate 34 and the extension plate 33 are fixed with the fixing bolts 35, thereby completing the assembly of the slide plate 37 and the fixed plate 31. By adding the filter component 3, the measured medium needs to pass through the filter component 3 before entering the transmitter assembly 1. The filter screen 314 can prevent particulate impurities in the measured medium from entering the transmitter assembly 1, avoiding the problem of clogging of the pressure tap of the pressure sensing unit. The filtered impurities naturally settle at the bottom of the fixed plate 31, improving the measurement accuracy of the transmitter assembly 1.

[0026] Meanwhile, when it is necessary to clean the impurities in the fixed plate 31 or replace the filter screen 314, the fixing bolt 35 can be removed, and then the assembly plate 34 and the slide plate 37 can be moved upward until the slide plate 37 and the filter screen 314 are moved out of the groove 36. Then, the threaded rod 317 can be rotated. After the threaded rod 317 is moved out of the insertion hole 315, the threaded ring 316 can be rotated upward to move the filter plate 312 outward. This filter assembly 3 is convenient for assembling and disassembling the filter screen 314, convenient for replacing the filter screen 314, convenient for use, and improves the filtration effect of the filter assembly 3.

[0027] Example 2: Figures 1-3As shown, the slide plate 37 has multiple grooves 310 symmetrically opened on the side facing the filter plate 312. Multiple sliders 313 are symmetrically fixedly connected to both ends of the filter plate 312. One end of the slider 313 is slidably connected to the inner side of the groove 310. An assembly plate 34 is welded to the top of the slide plate 37. Fixing bolts 35 are inserted into both ends of the assembly plate 34. An extension plate 33 is symmetrically welded to the top of the fixing plate 31. The bottom end of the fixing bolt 35 is threadedly connected to the top of the extension plate 33. Connecting pipes 32 are symmetrically fixedly connected to both sides of the fixing plate 31. One connecting pipe 32 is fixedly connected to one end of the solid base 12, and the other connecting pipe 32 is fixedly connected to one end of the single flange 2. A mounting base 11 is welded to the bottom end of the solid base 12, and the top end of the solid base 12 is fixedly installed to the bottom of the outer shell 13. A display 14 is fixedly connected to the front side of the outer shell 13.

[0028] The overall effect of this embodiment is that the measured medium enters the transmitter assembly 1 after passing through the filter assembly 3. When the pressure level in the measured container changes, the piezoresistive pressure sensor of the pressure sensing unit of the transmitter assembly 1 senses the pressure change and converts the pressure signal into an electrical signal. The electrical signal is transmitted to the signal processing unit, which amplifies and filters the electrical signal and then uses the built-in data processing algorithm to calculate the accurate pressure level value. The signal processing unit then transmits the processed pressure level data to an external device through the communication module.

[0029] The usage method and working principle of this device are as follows: When installing the filter assembly 3, first slide the sliders 313 at the four corners of the filter plate 312 along the slide groove 310 until one side of the filter plate 312 is completely in contact with the slide plate 37. Rotate the threaded ring 316 so that the axis of the threaded ring 316 and the axis of the insertion hole 315 are on the same straight line. Then rotate the threaded rod 317 until one end of the threaded rod 317 is inserted and fixed into the insertion hole 315, thereby fixing the filter plate 312 to one side of the slide plate 37. Then slide the slide plate 37 down along the groove 36 to the bottom wall of the groove 36. By setting a sealing rubber ring 38 at the top edge of the groove 36, the sealing rubber ring 38 can fill the gap between the slide plate 37 and the top of the groove 36, improve the sealing performance of the slide plate 37 and the fixed plate 31 after installation, and prevent media leakage. Finally, use the fixing bolts 35 to fix the assembly plate 34 and the extension plate 33, thereby completing the assembly of the slide plate 37 and the fixed plate 31.

[0030] By adding a filter assembly 3, the measured medium needs to pass through the filter assembly 3 before entering the transmitter assembly 1. The filter screen 314 can prevent particulate impurities in the measured medium from entering the transmitter assembly 1, avoiding the problem of clogging the pressure tap of the pressure sensing unit. At the same time, the filter assembly 3 facilitates the assembly and disassembly of the filter screen 314, making it easy to replace the filter screen 314.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
