WebThe venturi flow meter was calibrated with the standard flow meter (Coriolis flow meter) using flowing water. It is generally assumed that the discharge coefficient of a Venturi tube is constant, provided the pipe Reynolds number is greater than 2 × 10 5. The calibration was conducted at 1.9 × 10 5 < R e < 6.4 × 10 5 of water flow. The ... WebDec 7, 2024 · Follow this rotameter calibration procedure, step by step. Step 1. Start the flow of gas. Fluke recommends starting at the highest flow and working down. This results in better purging of the calibration gas, and better results at the lower flows. Step 2. Adjust the flow control/regulators to get to the test point. Step 3. inane chick
