　　If the medium contains iron or magnetic particles, a magnetic filter should be installed at the inlet of the flowmeter The magnetic filter is equipped with magnetic rods arranged in a spiral pattern to minimize pressure loss. Each magnetic rod is wrapped in polytetrafluoroethylene (PTFE) or stainless steel to prevent corrosion by the medium.

　　Type I: flange connection, height 100mm Type II: compression installation, height 50mm
