What does an inclined manometer measure?

An inclined manometer is specifically designed to measure low gas pressures, typically within the range of 0 to 10 inches of water column (inches W.C.). The inclined design allows for greater accuracy and sensitivity in readings, particularly at low pressure levels. By having its measuring tube inclined, even small changes in pressure result in noticeable vertical displacement of the liquid within the manometer, making the reading more precise.

Measuring pressures above 2" W.C. is within the operational capability of an inclined manometer, which can effectively handle readings within its designed range. The tool is commonly utilized in HVAC applications to measure static pressure in duct systems or to test gas pressure in appliance connections, thus ensuring that the system operates efficiently and safely.

Other choices do not align with the function of an inclined manometer. Temperature variations are measured with thermometers or temperature sensors, gas flow rates are typically gauged using flow meters or anemometers, and vibration levels are monitored using vibration analyzers or sensors. Each of these measures requires instrumentation designed specifically for their respective parameters and does not overlap with the functions of a manometer.
