    • PROBLEM TO BE SOLVED: To provide a simple and cheap portable type leakage sensor which can detect leak on a floor and leak from any instrument with the sensor located under it.
      SOLUTION: This sensor 10 is to detect presence of liquid, provided with a housing 12 which has concave top surface 14, concave undersurface 16, and peripheral wall 18 connecting these top surface 14 and undersurface 16, where the peripheral wall 18 extends below the undersurface 16 while extending above the top surface 14. Plural apertures are formed on the wall 18. Two or more conductive members 24 and 26 extend below the undersurface 16 while extending above the top surface 14, separated from each other by clearance 36 which can collect liquid. Those conductive members 24 and 26 are designed so as to generate output signal when any conductive liquid contacts the conductive members to fill the clearance 36. An output connector 30 is connected with two or more conductive members 24 and 26, configured so as to carry the output signal.

    • A fluid tank has a housing that has an upper end wall, a side wall, and a lower end wall that together define a cavity. A flexible diaphragm is connected to the side wall within the cavity and separates the cavity into an upper portion, which is sealed to contain a pressurized gas, and a lower portion, which is sealed to contain a pressurized fluid. An indicator is positioned in the upper wall of the housing and has an indicator arm and a visual indicator. The indicator arm is not visible and the visual indicator is visible with the indicator in a first position and the indicator arm is visible and the visual indicator is not visible with the indicator in a second position.
