What is the relationship between the meter coefficient of a vortex flowmeter and pipe diameter, flow velocity, and flow rate?
Each instrument has certain manufacturing errors when it is produced. By using actual flow calibration to set the instrument coefficients, these errors can be compensated for, thereby making the measured flow value more close to the true flow value and improving the accuracy of the instrument. Adjusting the instrument coefficients has a direct impact on the measurement results
There are too many issues to consider when it comes to vortex flow meters. 1. Diameter requirement: The flow rate must not be lower than the product’s minimum flow rate requirement. 2. There should be no significant vibration near the installation location. 3. Install it on the pipeline; no torsional stress should be applied to the flow meter. That is, after welding the two flanges on the pipeline, they should be aligned as much as possible, with no misalignment allowed 4. The straight pipe section must meet the requirements. Any problem in any of these steps will have an impact.
