1. Introduction
The ULTECHNOVO U-Shaped Stainless Steel Pressure Gauge is a precision instrument designed for accurate measurement of pressure differences in gas pipelines and other industrial systems. Constructed from robust stainless steel, this manometer offers durability and reliable readings within a 0-3000 Pa range. This manual provides essential information for the safe and effective setup, operation, and maintenance of your pressure gauge.
2. Product Overview
The U-shaped pressure gauge utilizes a liquid column to visually indicate pressure differentials. Its design emphasizes user-friendliness, portability, and versatility for various testing needs.

3. Setup
- Unpacking: Carefully remove the pressure gauge from its packaging. Inspect for any visible damage during transit.
- Placement: Position the gauge on a stable, level surface or mount it vertically using appropriate fixtures. Ensuring the gauge is level is crucial for accurate readings.
- Connection: Connect the appropriate tubing from the system to be measured to the inlet ports at the top of the U-shaped gauge. Ensure all connections are secure and airtight to prevent leaks that could affect accuracy.
- Liquid Level: Verify that the liquid column within the U-tube is at the zero mark or a known reference point before applying pressure.

4. Operating Instructions
To obtain accurate pressure differential measurements, follow these steps:
- Prepare the System: Ensure the system whose pressure differential you wish to measure is ready and stable.
- Connect the Gauge: Attach the gauge securely to the two points in the system where the pressure difference is to be determined.
- Observe Liquid Columns: Once connected, the pressure difference will cause the liquid in the U-tube to shift. Observe the new levels of the liquid columns.
- Read the Measurement: Read the values on the scale corresponding to the top of each liquid column. The difference between these two readings represents the pressure differential in Pascals (Pa).
- Disconnect: After measurement, carefully disconnect the gauge from the system.

5. Maintenance
- Cleaning: Regularly clean the exterior of the gauge with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the stainless steel finish or the measurement scale.
- Inspection: Periodically inspect the gauge for any signs of physical damage, corrosion, or wear on the connections. Ensure the U-tube is clear and free from blockages or contaminants.
- Storage: When not in use, store the pressure gauge in a clean, dry environment away from extreme temperatures, direct sunlight, and corrosive substances. Proper storage helps maintain its accuracy and prolong its lifespan.
6. Troubleshooting
- Inaccurate Readings:
- Check for leaks in the tubing connections. Ensure all connections are tight.
- Verify that the gauge is perfectly level. An unlevel gauge can lead to erroneous readings.
- Inspect the liquid column for air bubbles, which can interfere with accurate measurement. Gently tap the gauge to dislodge bubbles if present.
- No Liquid Movement:
- Confirm that the system being measured actually has a pressure differential.
- Check for blockages in the tubing or the gauge's inlet ports.
