A weir plate is a precision-engineered barrier used in overflow weirs and drainage systems to control liquid levels and flow rates in industrial processes.
Commonly used trade names and technical identifiers for Weir Plate.
This component is used in the following industrial products
A combined overflow and drainage component for stainless steel washing tanks that regulates liquid level and facilitates drainage.
A hydraulic structure within a separation chamber or launder designed to regulate and control the flow rate of liquids.
A raised barrier on distillation trays that controls liquid flow and maintains liquid level.
"The Weir Plate we sourced perfectly fits our Machinery and Equipment Manufacturing production line requirements."
"Found 35+ suppliers for Weir Plate on CNFX, but this spec remains the most cost-effective."
"The technical documentation for this Weir Plate is very thorough, especially regarding technical reliability."
The three primary types are rectangular (sharp-crested), V-notch (triangular), and trapezoidal (Cipolletti) weirs, each offering different flow characteristics and measurement accuracy for various applications.
Flow rate is calculated using standard hydraulic formulas based on crest geometry and liquid head. For rectangular weirs: Q = C × L × H^(3/2), where Q is flow rate, C is discharge coefficient, L is crest length, and H is head above crest.
Regular inspection for debris accumulation, corrosion checks, verification of crest sharpness (for sharp-crested weirs), and calibration against flow measurement standards to ensure accuracy.
