Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What materials are available for this orifice plate? **A**: The plate is available in Stainless Steel 316L, Hardened Tool Steel, and Food-Grade Polypropylene. Material selection depends on the application's corrosion, wear, and food safety requirements. Verify suitability with the manufacturer. ### Q: What is the flow accuracy of this orifice plate? **A**: The flow accuracy is ±2% of full scale, as per ISO 5167. However, actual accuracy depends on installation conditions and proper calibration. Confirm with the supplier for your specific setup. ### Q: How do I select the correct orifice diameter? **A**: Orifice diameter ranges from 10 to 100 mm. Selection is based on the required flow rate, allowable pressure drop, and pipe size. Use the flow coefficient (Cv) and consult the manufacturer or a flow control engineer for proper sizing. ### Q: Is this plate suitable for food-grade applications? **A**: Yes, the plate can be made from Food-Grade Polypropylene or Stainless Steel 316L, which are commonly used in food processing. However, ensure that all materials and sealing materials (e.g., PTFE) meet your specific regulatory requirements. Verify with the manufacturer. ## 6.
