U-Tube Manometer – Precision Instrument for Measuring Pressure Differences

The U-Tube Manometer is a simple yet highly accurate device used to measure pressure, vacuum, and pressure differences in gases and liquids. It operates on the principle of balancing a liquid column between two pressures and is widely used in physics, fluid mechanics, and engineering laboratories for experimental and calibration purposes.

Design and Construction

The U-Tube Manometer consists of a transparent glass tube bent in the shape of the letter “U”, partially filled with a manometric liquid such as mercury, water, or colored oil. One arm of the tube is connected to the pressure source, while the other arm remains open to the atmosphere or another pressure point.

Components:

• High-quality glass U-tube
• Graduated scale for accurate readings
• Stable base or stand for laboratory use
• Option for mercury or water filling depending on application

Key Features

• Simple and reliable pressure measurement
• Provides direct and accurate readings
• Durable, chemical-resistant glass construction
• Easy to use, maintain, and calibrate
• Suitable for educational, laboratory, and industrial purposes

Working Principle

The U-Tube Manometer measures pressure by comparing the difference in height (h) between the liquid levels in both arms of the tube. The difference in liquid height is directly proportional to the pressure difference between the two points, following the hydrostatic pressure equation.

Applications

• Physics and fluid mechanics experiments
• Calibration of pressure gauges and sensors
• Measurement of gas and airflow pressure
• Educational demonstrations in schools and colleges
• Industrial laboratories and HVAC systems testing

Benefits

• High accuracy and sensitivity
• No power source required
• Cost-effective and reusable
• Provides visual understanding of pressure difference
• Ideal for teaching fluid pressure principles
