Claims

[Scope of utility model registration request]

A stand column connected to the liquid tank via a connecting pipe, a float equipped with a permanent magnet installed inside this column that moves in response to changes in the liquid level, a side bay attached to the column, and inside this side cylinder. a plurality of Hall elements arranged in parallel at regular intervals; and at least one of the plurality of Hall elements.
The permanent magnet of the float has a number of resistors approximately corresponding to the number of Hall elements connected in series so that a return path of current can be formed from the connection point of the Hall element by changing the electrical constant such as resistance value. A liquid level gauge, characterized in that the liquid level can be detected by reading changes in the current flowing through the series resistor.
