Abstract

A predetermined amount of a diluent which mixes with a liquid leaking out of a liquid inlet of a container to dilute the liquid is poured into a recess formed in the liquid inlet, with the base part defined by a stopper fitted into the liquid inlet. The electrical conductivity of the diluted liquid in the recess is then measured. The leakage of liquid from the liquid inlet is detected by detecting whether the measured value is higher or lower than a predetermined level. This leakage detection method is particularly useful for detecting the leakage of beer from a barrel.

ビー ルを密封したビー ル撙 （ 金属製 ） は、 内部にガス を発生して内圧が高 く なつているために、 その ビー ル注 入 口の栓のガスバル ブ及びビ一ルバル ブパッキン グ不良 とねじの締め方が緩いと、 その部分から ビー ル が漏れ、 その結果市場においてカ ビ発生、 ガス抜け及び入味 （ 内 容 ） 不足とい う不具合を生じていた。  Since the internal pressure of the bead (metal), which sealed the bead, is increased due to the generation of gas inside, the gas valve and the valve valve of the stopper at the bead inlet are defective. If the screws were loosely tightened, the beads leaked from that area, resulting in mold, outgassing, and lack of filling (content) in the market.

To save labor, it has been considered to automate the sealing work of the vial inlet, but how to check for this leak was a problem. There is also a method for detecting bead leakage by measuring the gas pressure at the bead inlet with a manometer, but this method constantly monitors the water level at the manometer. It is necessary to control the outlet at a certain position, and the water level fluctuates.
( ガス圧 ） が極小でも検知可能かど うか疑間であった。  It was doubtful whether detection was possible even if the (gas pressure) was extremely small.
