Description

[0001] FLOW METERING APPARATUS [0002]

The present invention relates to a flow rate measuring apparatus using a tape measure, and more particularly, to a flow rate measuring apparatus using a tape measure capable of quickly and accurately measuring a change in a flow rate by inserting a buoyant body into a storage tank, .

Generally, a flow meter is used to measure the remaining amount of a liquid (hereinafter referred to as "fluid") such as oil, oil, or chemical contained in a storage tank.

In this conventional method, a long bar (tape measure) is inserted through the opening portion exposed on the upper surface of the storage tank, and the degree of the fluid flowing in the bar is discriminated. The other way is to hang the weight on the tape measure and put it into the opening. After the weight reaches to the bottom, the tape measure is lifted and the flow rate is measured according to the extent to which it is buried in the tape measure.

In this case, the latter method is difficult to insert or withdraw the tape measure into or out of the storage tank at the time of dispensing or withdrawing the flow rate, and the error rate of the flow measurement value is high, and it is necessary to take the tape measure to the end of the storage tank It takes a long time. Also, there is a concern that the tape measure with the fluid may seriously pollute the surroundings.

Hereinafter, a conventional prior art (patent document) related to the flow rate measuring apparatus described above will be described in detail in Korean Utility Model Application Nos. 20-2001-0002924 (2001.02.07) to Domestic Open Patent No. 10-2004-0098964 (Nov. 26.), and Korean Patent Laid-Open No. 10-2012-0011710 (Feb. 20, 2012), and the detailed description thereof will be omitted. However, the conventional prior art as described above is mainly a fixed type and is not only complicated in structure but also difficult to manufacture, expensive and expensive, and can be operated and handled at industrial sites such as oil storage tanks filled with oil, It is inconvenient to do so, and if the maintenance is difficult or neglected, the risk of malfunction or failure is very high, which is impractical and ineffective.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. According to the present invention, there is provided a flow rate measuring apparatus using a tape measure that measures an internal flow rate through an opening 202 of a storage tank 200 in which a fluid is contained. The flow rate measuring apparatus includes a post 10 A clamp 20 connected to the lower end of the post 10 and fixed to the opening 202 of the storage tank 200, a scale 32 on both sides thereof, and a connector 33 at the tip thereof, A flexible tape measure 30 wound around the take-up roll 34, a buoyant body 40 coupled to the end of the tape measure 30 and having a weight W inserted therein, A tensile weight 50 mounted between the clamp 20 and the indicator 32 for identifying the scale 32 of the tape measure 30 attached to the clamp 20, .

The above is explained in more detail as follows.

The tape measuring apparatus 100 according to the present invention measures a flow rate in the storage tank 200 and includes a post 10 and a clamp 20, a tape measure 30, a buoyant body 40, A tensile weight 50, and an indicator 60.

The post 10 is uprighted by a clamp 20 attached to the lower end and has a guide roller 16 at an upper end thereof to guide the tape measure 30. The clamp 20 is connected to the opening of the storage tank 200 202 to fix the post.

here The post (10) includes a second post (12) that is stretched and expanded by fitting in the longitudinal direction of the post (10); And a fixture (14) for fixing the second post (12). In other words, it is possible to measure accurately by stretching and shrinking up and down according to the depth of the storage tank part. Thus, the post 10 can be stretched and folded while the first post 12 is fitted in the inner longitudinal direction, and the length of the post 10 can be easily adjusted by fixing or releasing the side fastener 14.

A constant scale 32 is displayed on the surface of the tape measure 30 so as to accurately identify a change in the flow rate. The tip end of the tape measure 30 is provided with a connection port 33 to facilitate detachment and attachment of the buoyant body 40, 34). In particular, the tape measure 30 is made of a synthetic resin material instead of heavy steel material, and has good flexibility, corrosion resistance, and chemical resistance, so that the tape measure 30 has a long life and can easily remove contamination by fluids and foreign materials and can handle lightly. The winding roll 34 is equipped with a handle 35 to facilitate unwinding or winding the tape measure.

In this case, since the scales 32 and 32a are formed on both sides of the tape measure, the tape measure can be easily identified even in a frozen direction, and a part of the tape measure is erased.

The buoyant body 40 adhered to the end of the tape measure is provided with an inner space sealed up to be floated on the fluid by buoyancy force, and the weight W is embedded in the inner space, And it enters the storage tank and floats on the oil surface.

The buoyant body (40) has a hollow case (42) opened upward and a cover (44) for opening and closing the case (42); Hooks (45) for detachably attaching to the connector (33); And first to nth weights W1, W1a, W1b, ... W1n that are selectively inserted into the case 42 to vary the weight. That is, the buoyant body 40 is closed by closing the cover 44 by inserting the heavy object W into the hollow case 42, so that the buoyant body 40 is lowered by the weight of the heavy object and acts on the oil surface. A seal (44) is provided between the case and the cover to prevent leakage. The weight W includes at least one or a plurality of first to nth weights W1, W1a, W1b, ..., W1n, so that the correct height of the float can be maintained according to the viscosity of the fluid do. In this case, the first to nth weights W1, W1a, W1b, ... W1n are divided into various weights by dividing the weights in steps of about 10 to 1,000 g. Preferably, the first weight weight W1 is 120 g for low viscosity, the second weight weight W2 is 150 g for high viscosity, and the nth weight Wn is 350 to 450 g for depth measurement Do.

On the other hand, the weight W makes the buoyant weight of the buoyant body lighter and floats on the fluid, thereby measuring the height of the upper space of the buoyant body, that is, the height between the empty space and the oil level of the storage tank, It is suitable for measuring the remaining amount of fluid.

(Tank depth - upper space height = current residual height)

The case 42 of the buoyant body is provided with a stepped portion 43 having a lower end extending downward and a lowered space portion 43a formed therein. The surface tension is generated and the sense of floating on the surface can be easily determined.

The connector (33) is coupled to the hook (45) of the cover (44). The connecting port 33 and the hook 45 are provided for detachably attaching the buoyant body to the tape measure and are provided with a one-touch type opening / closing port in the 'C' type connecting port 33, . Therefore, if a conventional weight is attached instead of the buoyant body according to the present invention, measurement can be performed by a conventional method.

The tensile weights 50 attached to one side of the next tape measure are suspended from the tape measure 30 between the guide roller 16 and the take-up roll 34 so that the tape measure is not pulled tightly to be loosened, A clip 52 is provided. At this time, since the tensile weight 50 is lighter than the weight W, a tensile force acts on the tape measure so that the buoyant body does not separate from the oil surface.

The indicator 60 is attached to one side of the clamp 20 and indicates the scale 32 of the tape measure 30 so that it is possible to accurately identify the change of the scale according to the movement of the tape measure.

The flowmeter 100 using the tape measure configured as described above draws the tape measure 30 suspended from the buoyancy body 30 from the take-up roll 34 and into the openings. At this time, the post 10 So that it smoothly proceeds into the storage tank while being supported by the guide roller 16 at a constant height. The buoyant body (40) buoyantly acts on the oil surface of the fluid (L).

Thereafter, when the fluid is supplied to or discharged from the storage tank, the flow rate is changed and the buoyant body 40 is lifted or lowered. The scale change of the tape measure 30 is recorded and the flow rate is accurately measured. For example, as shown in FIG. 3, as the flow rate in the storage tank increases, the buoyant body rises, and the tape measure 30 is pulled by the tension weight 50, so that a tensile force acts to return naturally without loosening.
