Pressure measuring device for e.g. waste water treatment plant, has pressure sensor attached to air flowing lines and/or components e.g. compressors, and valves or automatic shut-off devices installed at end of lines and/or components

摘要

The device has a pressure sensor (11) attached to air flowing lines and/or components e.g. compressors (4), in such a manner that the pressure sensor is immersed in the fluid of a treatment process at an end of the air flowing lines and/or components in the region of the discharge of the air from the lines and/or components. The components are shutdown for producing compressed air, where a pressure measurement is implemented after the shutdown of the components. Multiple valves or automatic shut-off devices are installed at another end of the air flowing lines and/or components.
