体レベルセンサ。 In a level sensor that detects the level of a fluid by using a change in pressure applied to a piezoelectric vibrator as a change in the output of the piezoelectric vibrator, there is a mechanism for forming a gap between the piezoelectric vibrator and the fluid. A pressure transmission member is provided for applying a pressure change of the fluid to the vicinity of a vibration node of the vibrator through the flexible member, and the pressure transmission member is made of an elastic member such as a rubber material. A fluid level sensor characterized in that the fluid level sensor is configured to be formed and arranged in line contact with the piezoelectric vibrator.
