The inclined manometer is essential for retaining the most accurate pressure levels for industrial gas applications. A low-pressure industrial gas system may be used to heat or cool manufacturing processes. A small blockage within the gas system can be detected with an inclined manometer and corrected.
Measurement of Pressure:
Though pressure is an absolute quantity, every measurement is made relative to reference like ambient air pressure.
- Absolute Pressure: is referenced to zero(0) against perfect vacuum (=gauge pressure + atmospheric pressure)
- Gauge Pressure: is taken in reference with ambient air pressure.
- Differential Pressure: is the difference in pressure between two points.
