The pressure gauge should be checked before installing the Commercial Pressure Gauge, and it can be installed and used only after it is qualified. During installation, the pressure gauge should be fixed on a specially processed joint, and gaskets should be added; instead of winding hemp or directly on the valve.
The pressure gauge should be installed in a location convenient for operation and maintenance, The horizontal section of the connecting pipe should have a certain slope to facilitate the removal of condensed liquid or gas. When the measured medium is gas, the pipe should be inclined towards the pressure tap; when the measured medium is liquid, the pipe should be inclined towards the pressure measuring instrument; when the measured parameter is a small differential pressure value, it should be inclined The degree can be slightly larger. In addition, if the duct is at the upper and lower corners, according to the medium in the duct , a device for draining condensed liquid should be installed at the lowest point or an exhaust device at the highest point to ensure that condensation does not accumulate in the duct for a long time. Liquid or gas affects the accuracy of the measurement. Condensed liquid or gas should be discharged regularly.
