求の範囲第１項に記載の水位計検査装置。[Scope of claim for utility model registration] (1) Level switch type, level controller type, which has a float that moves up and down depending on water level fluctuations,
This is a water level meter inspection device that inspects a water level meter such as a level transmitting type as an object to be inspected, and includes a water storage tank with a sealed structure that holds a predetermined amount of water, and a sealed air chamber above the water surface inside this water storage tank that is at atmospheric pressure. An air pressurizing means for applying the above air pressure, and a float chamber made of a transparent cylindrical body installed above the water storage tank so that the water in the water storage tank is pushed up from near the bottom of the tank by the air pressure. A water level gauge inspection device comprising: a water level gauge to be inspected attached to the upper end of the float chamber to perform inspections such as operation tests of the water level gauge. (2) The float chamber consists of an upper flange for attaching a water level gauge, an intake and exhaust hole provided at the upper end of the chamber to allow air to freely enter and exit related to water level fluctuations in the float chamber, and The water level meter inspection device according to claim 1, which is characterized by being equipped with a water level measurement scale for measuring the water surface position within the water. (3) A water storage tank has a water inlet with a valve to inject water into the tank, a drain port with a valve to drain water from the tank, and a sealed air chamber above the water surface in the tank that has air pressure equal to or higher than atmospheric pressure. an air supply pipe which is connected to the upper wall of the tank and supplies pressurized air to a sealed air chamber above the water surface in the tank; Pressure regulating valve, air shutoff valve, to adjust air pressure
The water level meter inspection device according to claim 1, characterized in that the device is comprised of an exhaust pressure reducing valve. (4) The water storage tank has a chamber mounting cylinder that is fixed to the upper wall of the tank, hangs down into the tank, and has a lower end open near the bottom of the tank, and a float chamber can be attached to and removed from this mounting cylinder. The water level meter inspection device according to claim 1 of the utility model registration claim, characterized in that the water level gauge inspection device is flange-jointed to.
