Operating Principle:

The U tube manometer operates on a simple yet effective principle: difference in fluid height indicates differential pressure. When a pressure difference exists between the two ends of the manometer, the liquid column moves, creating a measurable displacement. This displacement is directly proportional to the applied differential pressure, allowing for precise measurement.

Advantages of this principle include:

• No electronic components, ensuring long-term reliability

• Highly accurate at low pressure ranges

• Visual feedback allows instant detection of pressure variations

• Minimal maintenance compared to electronic sensors

2. Connection: Attach 1/4″ SS nozzle to the pressure source using compatible tubing.

3. Fluid Filling: Fill the U tube with colored water or glycerin, ensuring no air bubbles remain.

4. Leveling: Ensure the manometer is vertical for accurate readings.

5. Zero Calibration: Before use, check the zero level of the fluid column to ensure correct baseline.
