Claims

[Scope of utility model registration request]

In a single-tube pressure gauge in which the lower end of a transparent measuring tube whose upper end opens into the atmosphere is connected below the liquid level of a pressure receiving tank storing liquid, the scale plate for reading the liquid level in the measuring tube is placed in the direction of the tube. At the same time, a transparent auxiliary tube is provided with one end opening into the air in the tank and the other end connected below the liquid level of the yarn tank, and the liquid level in the auxiliary tube corresponds to the scale plate. A single-tube pressure gauge characterized by adjusting the zero point.
