Pressure gauges (manometers)
Pressure gauges (manometers) – general information
General purpose pressure gauges designed for industrial applications. Widely used for pressure measurement of liquid and gas substances. Available in different types depending on pressure or vacuum that is to be measured.
A measuring range must be chosen according to working pressure, so that:
- constant or slowly fluctuating pressure does not exceed 75% of measuring range,
- pulsating pressure does not exceed 60% of measuring range,
- dynamic pressure impulses do not exceed the maximum measuring range.
Standard type have a 63 mm diameter, stainless steel case, glycerine fill, accuracy class 1,6″ and 1/4″ connection (bottom, back entry or for panel mounting).
When selecting a pressure gauge for measuring the pressure of gases above 25 bar or welding gases (acetylene and oxygen), please contact Tubes International.

FAQ – Pressure gauges:
The optimum measuring range of a pressure gauge is when the operating pressure is confined to 25% and 75% of the scale.
The accuracy class indicates the limits of permissible error and is expressed as a percentage of the full-scale range. There are the following accuracy classes: 0.1%, 0.25%, 0.6%, 0.5%, 1%, 1.6%, 2.5% and 4%.
Pressure gauges come in the following sizes: 40, 50, 63, 80, 100, 160 and 250.
The location of pressure gauge connection can be:
– bottom (radial),
– centric back ,
– eccentric back.
