  • Page 15: Insertion Type Installation

    If the length of upstream can not meet the requirement, suggest to install a flow regulator at the upstream pipeline. 2.2 Insertion Type Installation Straight Pipe Length Upstream≧15D, Downstream≧5D Recommendation 1. Open a Φ100mm round hole in the pipeline. The periphery of the hole should be free of burrs to ensure the vortex probe pass smoothly.
