Claims

[Scope of claim for utility model registration] 1. A portable pressure vessel 1 is equipped with an on-site remaining amount detection device A and a remote remaining amount detection device B, and the on-site remaining amount detection device A includes a float 10, a transmission rod 9, a remaining amount It consists of an operation tool 14 for displaying the amount, a bag tube 8, and a remaining amount display device 15, and a pressure-resistant bag tube 8 for guiding up and down is attached to the upper part of the pressure vessel 1.
A transmission rod 9 is fixed so as to project upward and communicate with the inner space Y of the container, and a transmission rod 9 is inserted between the pressure vessel 1 and the bag cylinder 8 so as to be able to rise and lower freely.A float 10 is attached to the lower part of the transmission rod 9, and the transmission rod An operating tool 14 is attached to the upper part of the bag tube 8, a remaining amount indicator 15 is provided on the outside of the bag tube 8, the operating tool 14 and the remaining amount indicator 15 are made of a magnetic material, and at least one of them is made of a magnet, It was housed in a portable pressure vessel configured to display the height at which the float 10 floats due to the buoyant force received from the fluid contained in the pressure vessel 1 on a remaining amount indicator 15 via a transmission rod 9 and an operating tool 14. In the on-site/remote fluid remaining amount detection device, the remote remaining amount detection device B uses a remaining amount sensor S to detect at least one of the height position of the operating tool 14 and the remaining amount display height position of the remaining amount indicator 15. The remaining amount sensor S is placed at a position corresponding to one of the operating tool 14 and the remaining amount indicator 15 on the outside of the bag tube 8, and the remaining amount indicator 15 is entirely covered. An on-site/remote residual amount detection device for a fluid contained in a portable pressure vessel, characterized in that the device is attached in a state where there is no pressure. 2. The remaining amount sensor S comprises a magnetic resistance element 30, and the magnetic resistance element 30 is configured to operate in response to magnetic force generated from at least one of the attachment device 14 and the remaining amount indicator 15. An on-site/remote residual amount detection device for the fluid contained in the portable pressure vessel described above. 3 Remaining amount sensor S is magnetic force-strain conversion member 34
This magnetic force-strain converting member 34 is fixed in a cantilevered manner along the moving direction of the operating tool 14, and the strain gauge 35 is attached to the fixed side end 34a of the magnetic force-strain converting member 34. The magnetic force-strain conversion member 34 is strained by the magnetic force generated from at least one of the mounting and operating tool 14 and the remaining amount indicator 15, and the amount of strain is detected by the strain meter 35. On-site/remote residual amount detection device for fluid contained in a portable pressure vessel. 4 The remaining amount sensor S is composed of a light emitter 38 and a light receiver 39, and these light emitter 38 and light receiver 39 are provided facing the remaining amount indicator 15, and light is emitted from the light emitter 38 toward the remaining amount indicator 15 side. The light is sent to the receiver 39
2. The on-site/remote residual amount detection of the fluid contained in the portable pressure vessel according to claim 1, wherein the presence or absence of the remaining amount indicator 15 at the position where the light is projected is detected based on whether or not the light is received. Device.
