Install Parshall Flume, Civil Work

 

2. Prepare the Flume

• Inspect the Flume: Check for damage or irregularities that might affect its installation or operation.
• Seal the Joints: If the flume is made of multiple sections, assemble and seal the joints with waterproof materials like silicone or epoxy.

 

3. Position the Flume

• Align with the Flow: Place the flume in the channel, ensuring it is centered and aligned with the direction of flow.
• Set the Invert Elevation: Ensure the flume’s throat (the narrowest part) is at the correct elevation relative to the flow line. Use a level or laser leveling tool for accuracy.
• Check for Levelness: Ensure the flume is level from side to side and properly sloped in the direction of flow as specified by the manufacturer.

 

5. Install Accessories

• Flow Measurement Devices: Attach any required flow meters, staff gauges, or ultrasonic sensors according to manufacturer guidelines.
• Connect Upstream and Downstream Channels: Ensure smooth transitions at the inlet and outlet to minimize turbulence and ensure accurate measurements.

 

6. Test the Installation

• Inspect for Leaks: Run water through the flume to check for leaks or misalignments.
• Verify Measurements: Compare flow readings with expected values to confirm accuracy.
• Adjust if Necessary: Make any necessary adjustments to the alignment, level, or sealing.

 

7. Maintenance and Calibration

• Regularly inspect the flume for sediment buildup, blockages, or wear.
• Calibrate measurement devices periodically to ensure continued accuracy.
