A second container 200 is formed, the outer lower portion is formed with a coupling means 240 is coupled to the first container, the second opening portion is formed higher than the height of the first opening; do.

In a machine that processes a gas or liquid, specific gravity is measured to provide an accurate volume of the object to be measured. Especially in continuous processes, the specific gravity must be measured continuously. The continuous measuring hydrometer of the present invention aims at measuring the continuous specific gravity of a liquid. For continuous specific gravity measurement, a first vessel containing a liquid and a load cell for weighing the liquid are formed. The first container forms a first accommodating space therein to accommodate the liquid, and the upper part of the first container forms a first opening to inject the liquid into the first accommodating space and discharge the liquid. The lower part of the container is equipped with a load cell, and continuously measures the liquid weight of the first receiving space. The load cell checks the weight of the container as an initial value, and calculates only the weight of the liquid to be added.

(Example 1-2) In Example 1-1, the first container includes a transparent material.

An object of the present invention is to visually check the amount of liquid contained in the first container. In order to implement this, the first container material is formed of a transparent material.

The liquid introduced into the second container is moved to the first container, and the liquid contained in the first container is discharged to the outside. As the liquid moves from the second vessel to the first vessel, it is possible to measure continuous specific gravity variation. If the heights of the first container and the second container are the same, the liquid may be moved from the upper part of the second container to the upper part of the first container without being circulated. In order to prevent this, the second opening position is formed higher than the first opening position.

When a plurality of first containers are accommodated, the liquid discharged from each first container is collected in one third container. When formed in plural, it is possible to measure plural specific gravity in one procedure, which can obtain the accuracy of the measurement result.

For real-time specific gravity measurement, the first vessel proceeds with the liquid input and discharge continuously. The discharge guide of the present invention aims to guide the discharge liquid. Since the discharge liquid overflows through the first opening, the discharge liquid is discharged along the outer surface of the first container. At this time, the weight of the liquid buried on the outer surface of the first vessel is measured together with the load cell to generate an error. In order to prevent the error, the discharge liquid is discharged through the discharge guide so that it is not attached to the outer surface of the first container.

(Example 10-2) In Example 10-1, the discharge guide is formed in the discharge guide, a plurality of, is formed into a groove; the discharge groove;

The liquid is ejected to the supply pipe discharge port, and the liquid is dropped and supplied to the upper surface of the first container. Falls cause impact loads, making accurate measurements impossible. In order to prevent this, the discharge port is equipped with a feed guide. The feed guide band guides the liquid input direction by using the surface tension, and minimizes the drop impact. The feed guide band forms a guide groove, one side of the feed guide band forms a discharge port and a mounting and detachable mounting port, and the other side of the feed guide band forms a plurality of input rods. The plurality of input rods disperse the input direction, reducing the drop impact force.

(Example 11-4) In the above-described embodiments, the filter unit 600 formed in the supply pipe; includes.

The filter container is fastened by the supply pipe and the fastening means. This is to facilitate filter replacement. The filter inlet fastens the filter. That is, the liquid and foreign matter entering the filter inlet are filtered through the filter, and only the liquid passes through the filter.

The liquid discharged from the first vessel is discharged radially from the upper side of the first vessel along the discharge guide. The discharged liquid falls into the third container and generates an impact upon falling. To prevent this, sliding plates are formed. The sliding plate is attached to the inner side of the third container, and forms a sloped surface so that the liquid falls on the sloped surface. This reduces the drop impact. Also, in order to prevent the liquid from penetrating into the load cell, the blocking plate is coupled to the third container bottom plate to stand up in a cylindrical shape, and accommodates the load cell and the first container therein.

The third accommodation space accommodates the liquid discharged from the first container. The liquid in the third accommodation space is discharged to the outside through the drain pipe. A drain valve is mounted inside the drain pipe to control the discharge. The drain valve is operated manually or automatically. In the case of automatic operation, the water level sensor is mounted in the third accommodation space inside the third container, and a solenoid valve controlled according to the water level sensor signal is mounted. The water level measuring sensor includes a ball top, an ultrasonic sensor, a gap sensor, and an object capable of achieving a similar purpose and effect. The lower surface of the third vessel forms an inclined surface. This is to ensure that the liquid discharge is complete by gravity. The drain pipe is formed at the lowest position among the inclined surfaces.

Embodiment 16-1 In the embodiments described above, an indicator 350 is attached to the outside of the third container and outputs a load cell signal.

(Example 17-1) In the above-described embodiments, the coating layer 800 is formed inside and outside the first to third containers.

It is preferable to block the contact between the liquid and the container (first to third containers). In particular, if a resistance of the flow is generated by inducing surface tension between the liquid and the container, a problem arises in that the specific gravity cannot be measured. To overcome this, the interior and exterior of the container is coated. The coating may form a technique layer to lower the coefficient of friction or to form a nano-sized water repellent layer.

In addition, the signal of the load cell represents a signal containing both the weight of the first vessel and the second vessel. Therefore, the first and second containers are removed from the signal of the load cell, and the weight of the purely measured liquid is analyzed first.

(Example 4-5) In Example 4-1, the alarm means 530 warns when the converted value is out of a predetermined range.

The hydrometer continuously measures the specific gravity of the liquid. If it is out of the proper specific gravity range due to the mixing ratio error of the mixed liquid during the measurement process, a warning is generated through the alarm means. The specific gravity places a boundary between the upper and lower bounds and generates a warning if the threshold is out of bounds. The warning is generated through the siren 531, the lamp 532, the buzzer 533, and even to achieve the same purpose and effect.
