An Inclined Tube Manometer is a precision instrument used for measuring very low differential pressures with high sensitivity and accuracy. It consists of a transparent tube mounted at a specific angle to the horizontal, partially filled with a manometric liquid. The inclined design increases the measurement scale length, allowing small pressure differences to be measured more accurately than conventional vertical manometers.
Inclined Tube Manometers are widely used in laboratories, HVAC systems, clean rooms, air handling units, dust collection systems, ventilation systems, and industrial process applications where precise low-pressure measurement is essential. Their simple construction, reliable operation, and high accuracy make them an ideal choice for monitoring air, gas, and low-pressure process systems.
These instruments provide direct visual pressure indication without requiring any external power source, making them economical, dependable, and easy to maintain.
