Claims

[Scope of utility model registration request]

A transparent U-shaped tube and a measuring liquid injected into the U-shaped tube are provided, and a scale plate for measuring a first liquid level of the liquid at one side of the U-shaped tube is provided, a first mirror surface that reflects the second liquid level so that mirror images of the second liquid level of the liquid on the other side of the U-shaped tube can be visually observed in parallel when measuring the first liquid level with the plate; And this first
and a second mirror surface disposed on the side of the scale plate at right angles to the mirror surface.
