PURPOSE:To make measurement possible even if a fuel tank deforms, by installing equi-potentially a plurality of sheet dielectrics and the fuel tank, and improving operationability of assembly by detecting a balance of fuel from change of electrostatic capacity between opposedly arranged sheet dielectrics. CONSTITUTION:The first electrode is made of electrically connected sheet dielectrics 1, 3 and the second one of electrically insulated other dielectrics 2 positioned in-between in an opposed manner. The first electrode is assembled in a fuel tank in such a way that it is equi-potential with the tank and the fuel balance is detected from change of electrostalical capacity between two electrodes. Thus, easier assembly is available by a compact entire construction without sacrificing decting sensibility and measurement can be continued even if a deformed tank happens to contact the first electrode. |
