Quadrant Edge Orifice Plate Manufacturer in Mumbai India
        Asre Engineering is a trusted Quadrant Edge Orifice Plate manufacturer in Mumbai, India, supplying precision-engineered flow measurement solutions for low Reynolds number and viscous fluid applications.
       Our Quadrant Edge Orifice Plates are specifically designed for accurate flow measurement of low flow rates, slurries, and highly viscous liquids where conventional concentric orifice plates fail. Manufactured in compliance with ISO 5167 principles, our plates ensure repeatability, stability, and long service life across demanding industrial environments.
       In processes where suspended solids and debris are present, accurate flow measurement is often complemented by effective filtration and straining solutions. For upstream protectionÂ
of flow instruments and piping systems, Asre Engineering also recommends the use of industrial strainers and filtration equipment manufactured by our associate division. To explore high-quality Y strainers, basket strainers, and custom industrial strainers, visit our dedicated strainer manufacturing website at asrengineering.com, engineered to support reliable and clog-free process operations across industries.
Why Our Quadrant Edge Orifice Plate Stands Out
High Accuracy at Low Reynolds Numbers – Ideal for laminar and transitional flow regimes
Rounded Quadrant Edge Profile – Minimizes flow separation and pressure loss
Custom Machined Precision – CNC-machined for exact quadrant radius
Wide Material Availability – SS 304, SS 316, Duplex, Monel, Hastelloy
Long-Term Stability – Consistent discharge coefficient over time
Low Maintenance Design – Reduced clogging and erosion
Working Principle – How Our Quadrant Edge Orifice Plate Works
A Quadrant Edge Orifice Plate operates by restricting fluid flow through a rounded inlet edge (quadrant radius) instead of a sharp edge.
How It Works:
Fluid approaches the rounded quadrant edge
Smooth acceleration reduces turbulence
Stable differential pressure is generated
Flow rate is calculated using ΔP and fluid properties
This design makes it ideal for low Reynolds number flow measurement, unlike sharp-edged orifice plates.
