DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, although the present invention is not limited thereto.

[0014] Please refer to Fig. 1. As shown in Fig. 1, a liquid level monitoring and quality monitoring system according to one embodiment of the present invention includes a container 10 and a pipe 20.

[0015] A storage space 11 is formed within the container 10. A liquid A is stored within the storage space 11. The liquid level of the liquid A within the storage space 11 is a first liquid level A1.

[0016] The tube body 20 includes a first step 21, a first bent portion 22, a second step 23, a second bent portion 24, and a third step 25 that can be seen through. The first step 21 has a first opening 211 at one end and the first bent portion 22 connected to the other end. The other end of the first bent portion 22 is connected to one end of the second step 23. The other end of the second step 23 is connected to the second bent portion 24. The other end of the second bent portion 24 is connected to one end of the third step 25. A second opening 250 is provided at the other end of the third step 25. Liquid A flows through the first opening 211 to the third step 25, and the liquid level of liquid A in the container 10 is determined by the second liquid level A2, which is at the same height as the first liquid level A1 formed in the third step 25.

[0017] The container 10 may have a lid 101 at the top, as needed, or may be molded into a one-piece, closed container 10 and closed with the lid 101. If the liquid A in the container 10 is volatile, a predetermined pressure is generated inside the container 10 when the container is evacuated or when nitrogen gas pressure is maintained. Therefore, a second opening 250 may be formed in the lid 101 or at the top of the container 10, and an extended step 26 and a valve element 261 may be connected to the third step 25. When the valve element 261 is disposed between the extended step 26 and the third step 25, and selectively opening or closing the valve element 261 connects the extended step 26 and the third step 25, the predetermined pressure is balanced with the external pressure, and the height of the second liquid level A2 becomes equal to the height of the first liquid level A1.

[0018] Please refer to Fig. 2. As shown in Fig. 2, the container 10 is placed on a weighing scale 30. The weighing scale 30 includes a display 31 or a remotely controllable monitoring system. A first reference weight value and a second reference weight value are set in the weighing scale 30. The second reference weight value is greater than the first reference weight value.

[0019] Liquid A is poured into container 10. When the weight of liquid A is equal to the first reference weight value, second liquid level A2 of liquid A is located at low scale line 251 provided on third step 25. When the weight of liquid A is equal to the second reference weight value, second liquid level A2 of liquid A is located at high scale line 252 provided on third step 25.

[0020] For example, when the weight of the empty container 10 is set to 0 and the specific gravity of liquid A is 1, the first reference weight value is set to 500 g, and when the weight of liquid A is equal to the first reference weight value, the second liquid level A2 of liquid A is located at the low scale line 251. When the second weight value is set to 3500 g, and the weight of liquid A is equal to the second reference weight value, the second liquid level A2 of liquid A is located at the high scale line 252.

[0021] In other words, when the third step 25 is used to observe that the second liquid level A2 is equal to the low scale line 251, the amount of liquid A is 0%. When the third step 25 is used to observe that the second liquid level A2 is equal to the high scale line 252, the amount of liquid A is 100%. The user can set the relationship between weight and liquid level and monitor the liquid level using the third step 25.

[0022] If the specific gravity of Liquid A is greater than 1, the first liquid level A1 will be lower than the low scale line 251, allowing the user to quickly determine whether the wrong liquid has been input or whether Liquid A has been contaminated and its specific gravity has changed. Therefore, when actually performing quality control (QC), an operator can quickly determine whether the amount of Liquid A in the container 10 is accurate based on the weight and liquid level.

[0023] See FIG. 3. As shown in FIG. 3, the user may use the tube 20 and weighing scale 30 simultaneously or separately as needed. When the tube 20 is not in use, the first liquid level A1 of the liquid A having the first reference weight value is equivalent to being positioned at the low level line, and the first liquid level A1 of the liquid A having the second reference weight value is equivalent to being positioned at the high level line. The weighing scale 30 transmits data to a distributed control system or a programmable logic controller (PLC). That is, the height of the first liquid level A1 when the weight of the liquid A varies can be calculated, and the liquid level can be determined from the weight for quality control.

[0024] The type of the weighing scale 30 of the present invention is not limited, and it can be used for weighing several tens of cubic meters (m 3 Alternatively, the weight reading of the weighing scale 30 may be performed by a human-machine interface capable of long-distance communication.

[0025] Please refer to Fig. 4. It should be noted here that the other embodiment shown in Fig. 4 has the same main technical means as the above-mentioned embodiment, and therefore the same parts will not be described again.

[0026] In addition to being used to monitor liquid A, the present invention may also be used to attach powder B to container 10. Powder B is an aggregate of solid fine particles.

[0027] This method is used to convert the weight and level of powder B, and simultaneously monitors quality control to determine the original purity of powder B. It also determines the particle size and determines the bulk density. By placing powder B in a level gauge with a fixed height and using a stable vibrator, powder B in container 10 reaches a stable first level B1. At this time, the measured weight and the corresponding level are regarded as the starting point for correction. When powder B with different particle sizes or different components is added, the final bulk density will not necessarily be the same, so it can be determined whether the quality of the powder meets the requirements.

[0028] If the particle size or bulk density of powder B does not meet the requirements, the first level B1 has the same effect on the corresponding weight, allowing you to quickly determine whether the density or ingredients meet the standards.

[0029] Furthermore, the weighing scale 30 may be installed on the funnel portion, and the method of shipping by volume using only a level meter may be changed to a shipping method that combines volumes.

[0030] The above description is merely a preferred embodiment of the present invention, and although the preferred embodiment of the present invention has been disclosed as above, it is by no means intended to limit the present invention. Various changes and modifications can be made within the scope of the present invention. Therefore, the scope of the claims of the present invention should be broadly interpreted to include such changes and modifications. [Explanation of symbols]
