发明名称 FLUID LEVEL DETECTING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a fluid level detecting device having a simple configuration and capable of being easily attached to a tank. SOLUTION: This fluid level detecting device is provided with a sensor part 1 expressing electric capacity according to the fluid level of a fluid in a tank TNK, and a detecting circuit part 2 detecting the fluid level of the fluid based on the electric capacity given from the sensor part 1. Particularly, the sensor part 1 has a length corresponding to a measuring range of the fluid level, and contains a twisted pair wire 11 extending over the measuring range in the tank TNK. Since the electric capacity according to the fluid level is given by the twisted pair wire 11, the fluid level can be detected by using this. COPYRIGHT: (C)2006,JPO&NCIPI
