Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement, in particular to a liquid level measuring device and storage equipment. Background Art

[0002] The sealed storage tanks used by the company use a two-color magnetic flap level gauge to detect and display the liquid level. The float of the two-color magnetic flap level gauge has a magnetic float that moves with the liquid level in the tank. The magnetic steel in the magnetic float is transmitted to the flap indicator through magnetic coupling, driving the two-color magnetic flap to rotate 180°. The boundary between the two colors of the two-color magnetic flap is the actual height of the liquid level in the tank. At the same time, the liquid level can be read on the panel scale of the flap indicator to realize on-site display; a remote transmitter associated with the magnetic float is installed on the top of the float to realize the remote transmission function.

[0003] However, after the magnetic float fails, both the on-site and remote transmission will not display the actual liquid level (some magnetic flap level gauges do not have remote transmission function), affecting the process operation. Utility Model Content

[0036] First, see Figure 1-2 This embodiment provides a liquid level measuring device, including a magnetic flap liquid level gauge 1, a differential pressure liquid level gauge 2, a first three-way structure 3 and a second three-way structure 4.

[0037] The magnetic flap level gauge 1 comprises a buoy 11 , a magnetic float 12 , a flap indicator 13 and a remote transmitter 14 .

[0038] The upper part of the float 11 has an upper interface and the lower part has a lower interface; the float 11 is connected to the storage device 5, and the storage device 5 has an upper detection port on the upper part and a lower detection port on the lower part; the lower end of the float 11 is connected to a drain valve 15, which is used during cleaning or debugging.

[0039] The magnetic float 12 is movably arranged in the buoy 11 .

[0040] The flap indicator 13 is fastened to the outer wall of the float 11 by a clamp 16. A plurality of magnetic flaps 17 used in conjunction with the magnetic float 12 are arranged inside the flap indicator 13. The plurality of magnetic flaps 17 are arranged longitudinally. A panel scale (not shown in the figure) used in conjunction with the magnetic flaps 17 is arranged outside the flap indicator 13. In a specific implementation scenario, the colors of the magnetic flaps 17 include red and white, and there is a boundary between the two colors.

[0041] The remote transmitter 14 is installed on the top of the buoy 11 and is used in conjunction with the magnetic float 12 .

[0042] The differential pressure level gauge 2 has a first connection flange 21 and a second connection flange 22; the differential pressure level gauge 2 can be installed at a designated location on site through a bracket (not shown in the figure), preferably installed near the storage device 5 and the magnetic flap level gauge 1 to reduce the length of the line supporting the differential pressure level gauge 2. In a specific implementation scenario, the differential pressure level gauge 2 has a remote transmission function (realized by a remote transmission device).

[0043] The first three-way structure 3 is used to connect the upper interface, the first connecting flange 21 and the upper detection port.

That is, a new liquid level detection scheme is added, so that when the magnetic float 12 of the magnetic flap level gauge 1 fails, the actual liquid level in the storage device 5 is detected and displayed by the differential pressure level gauge 2 to ensure the normal operation of the process.

[0047] In addition, although the present embodiment adds a differential pressure level gauge 2, no additional measuring opening is added to the storage device 5. While improving the reliability of liquid level detection and display, it also has the advantages of easy modification and no impact on the structure of the storage device 5.

[0048] Second, see Figure 1-2 This embodiment provides a storage device 5, including the above-mentioned liquid level measuring device. The storage device 5 is a storage tank. In a specific implementation scenario, the storage device 5 is a sealed storage tank.
