- **Caution**: 

### Q: What materials are available for weir plates in machinery manufacturing?
**A**: Weir plates are available in carbon steel for general use, stainless steel for corrosion resistance, and abrasion-resistant steel for high-wear applications in mud tanks and pits.

### Q: How do adjustable weir plates control fluid separation in mud tanks?
**A**: Adjustable weir plates feature mounting brackets and adjustment mechanisms that allow precise positioning to regulate fluid flow levels, enhancing separation efficiency in sedimentation processes.

### Q: What components are included in a weir plate BOM for installation?
**A**: A complete weir plate bill of materials includes the plate itself, mounting brackets for secure attachment, an adjustment mechanism for flow control, and sealing gaskets to prevent leaks in tank/pit systems.

## 6. Manufacturing Compliance
- DIN 1952: FLOW MEASUREMENT WITH STANDARD NOZZLES, ORIFICE PLATES AND VENTURI TUBES
