Abstract
Official abstract text for this publication.
A liquid level detecting device includes a first detecting part that has a first electrode extending in a vertical direction in the tank and opposing to a ground electrode and detects a first electrostatic capacity between the first electrode and the ground electrode, a second detecting part that has a second electrode extending in the vertical direction in the tank and opposing to the ground electrode and detects a second electrostatic capacity between the second electrode and the ground electrode, and a difference calculating part that calculates a difference between the first electrostatic capacity detected by the first detecting part and the second electrostatic capacity detected by the second detecting part as a capacity difference and determines whether the liquid level in the tank is above a warning threshold.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid level detecting device for detecting a liquid level of liquid in a tank comprising a first detecting part that has a first electrode extending in a vertical direction in the tank and opposing to a ground electrode and configured to detect a first capacitance between the first electrode and the ground electrode; a second detecting part that has a second electrode extending in the vertical direction in the tank and opposing to the ground electrode a…
