Problems solved by technology

[0009] If the bubble level gauge is used to detect the liquid level of the ship's ballast water, since the air bubbles will supply oxygen to the water in the cabin, it is easy to cause bacteria to activate in the water and cause proliferation.

Embodiment Construction

[0080] Next, embodiments of the hydraulic pressure measurement unit and the liquid level gauge of the present invention will be described with reference to the drawings.

[0081] 【Example】

[0082] [Example of Hydraulic Measurement Unit]

[0083] exist figure 1 , figure 2 Among them, the hydraulic pressure measurement unit is configured to have a flange 1 and a pressing flange 2 overlapping with the flange 1 . Both the flange 1 and the pressing flange 2 are made of a high-strength material such as metal and have a circular outer peripheral shape. The flange 1 is in the shape of a disc, and the pressing flange 2 is in the shape of a ring with a central hole 28 .

[0084] as Figure 5 As shown, in the flange 1, an O-ring groove 11 is formed along the entire circumference along a circle concentric with the outer circumference. Continuing with the outer peripheral edge of the O-ring groove 11, a circular jetty 15 viewed from a planar direction is formed along the entire cir...

Abstract

The present invention provides a hydraulic measuring unit and a liquid level gauge using the hydraulic measuring unit, which can not only avoid the aeration of the measurement object, the prevention of the growth of the bacteria, the influence of the static region, The A pressure measuring unit includes a diaphragm (5) having a pressure receiving surface on the one surface side of the liquid to be measured, and the other side facing the air chamber (6) as a pressure receiving surface; a compressed air supply port, The air chamber (6) is provided with an opening; and an exhaust port whose open end (71) is opposed to the diaphragm (5) in the air chamber (6). The open end (71) and the diaphragm (5) of the exhaust port are lip-shaped structures which are balanced by the pressure applied to the pressure receiving surface and the pressure applied to the air chamber (6), and the open end (71).

Description

technical field [0001] The present invention relates to a hydraulic measuring unit and a liquid level gauge using the hydraulic measuring unit. Background technique [0002] In ships such as container ships and oil tankers, liquid level gauges for detecting the liquid level of stored liquid are respectively provided for each ballast tank or cargo oil tank. The bubble level gauge is one of the measurement methods of this kind of liquid level gauge. The structure of the bubble level gauge is to install an air supply pipe from the bottom to the upper end of the liquid chamber, supply compressed air to the air supply pipe submerged in the liquid stored in the chamber, and discharge air bubbles from the lower end of the air supply pipe. The principle of the bubble level gauge is: Since the air pressure in the suction pipe will vary according to the liquid level of the liquid stored in the cabin, that is, the height of the liquid level, the height of the liquid level can be measu...
