Operating conditions for vortex flowmeters
Thread Content
Medium temperature: 50°C, ambient temperature: 60°C. Can a vortex flow meter be used to measure natural gas?
No problem. I also need to inform the manufacturer of parameters such as diameter, pressure, minimum flow rate, maximum flow rate, and typical flow rate
1. The temperature should not be too high; the suitable temperature ranges vary from one manufacturer to another. 2. There are strict limitations on flow rate, and this is very important. 3. The straight pipe section must be satisfied, as this is dictated by its measurement principle. 4. The viscosity cannot be too high; this is also due to the principles behind its measurement. 5. There are strict requirements for installation, especially as vibration has a significant impact on it. 6. Another requirement related to installation that is often overlooked is that there should be no significant torsional stress in the pipes on both sides of the vortex flow meter during installation. It’s hard to determine this; special attention must be paid during on-site installation.
Based on the parameters you provided, it’s feasible. It’s best to provide the manufacturer with the minimum, normal, and maximum flow rates before making a selection; including compensation factors is even better. After all, natural gas comes at a cost, so choosing a more appropriate and accurate meter helps avoid trade disputes. However, most systems these days use gas turbines for measurement, as they are more stable
Gas turbines are used for high flow rates, while Roots pumps are used for low flow rates; nowadays, both types come with intelligent compensation features.
