する。[Detailed Description of the Invention] [Summary] The present invention provides a liquid level control system equipped with a float, a reed switch, and an alarm device in order to remotely control the storage limit level of a mobile phase solvent in a liquid chromatograph LC. The level alarm device makes it possible to set, detect, and warn the critical liquid level.0 [Industrial Application Field] The present invention provides a liquid level alarm equipped with an alarm device using a float, a reed switch, and an electric circuit. This invention relates to a storage tank for LC with equipment.

隔検知できる装置が必要とされる。In LC, the mobile phase solvent is usually stored in an amber bottle, which is placed at a level above the human body.The solvent is constantly being sucked out, so the liquid level decreases over time. , a critical liquid level t in a storage tank for LC - a device capable of remote sensing is required.

ていた。Conventionally, LC storage tanks were dark-colored and installed at a higher position than the human body, so the liquid level could not be detected remotely, and the user could directly detect a drop in the liquid level in the DL storage tank. It required a lot of effort because it was being monitored.

１１を伴う電気回路は通電し、警報器が作動する。The mobile phase solvent 1 is supplied from the suction pipe 3 in the LC storage tank 2.
Since it is constantly being suctioned, the liquid level will drop slightly from time to time. The float 4 is suspended by a metal wire 5 passing through a gas vent hole 6. The tip of the suction pipe 13' is the 0 limit liquid level where the liquid level can be set by the length of the metal wire.
When the float reaches a little above the metal wire and the metal wire is no longer slack, the reed switch 7 comes into contact with the magnet 8, and the electric circuit including the battery 10 and the alarm 11 is energized, and the alarm is activated.
