Abstract

PURPOSE:To obtain a measured value of high accuracy, which requires no compensation, by fetching a liquid level signal by a binary or binary-coded-decimal signal by a matrix circuit using a diode which is very strong to heat. CONSTITUTION:Plural lead switches F1-Fn for a contact (c) operated by magnetism are arrayed. Also, a sensor part 2a constituted so as to be displaceable along the arraying direction of the lead switches F1-Fn is provided so that the variation of a float 4 equipped with a magnetic followed by that of a liquid level. Furthermore, this level gauge is provided with an operation and output part 2b consisting of a diode matrix circuit constituted so as to operate a liquid level from a switching state of each lead switch F1-Fn in the sensor part 2a and to output a result of its liquid level operation by a binary signal or a binary-coded-decimal signal.
