Segmental Orifice Plate manufacturer in Mumbai India
Asre Engineering is a leading Segmental Orifice Plate manufacturer in Mumbai, India, specializing in high-accuracy differential pressure flow measurement solutions for challenging flow conditions. Our segmental orifice plates are engineered for fluids containing suspended solids, slurries, viscous liquids, and dirty gases, where conventional concentric orifice plates fail.
With precision CNC machining, international standards compliance, and custom manufacturing capabilities, Asre Engineering supplies segmental orifice plates across India, the Middle East, Africa, and Southeast Asia.
In processes where suspended solids and debris are present, accurate flow measurement is often complemented by effective filtration and straining solutions. For upstream protection
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 Segmental Orifice Plate Stands Out
Our segmental orifice plates are designed to deliver stable flow measurement, even under severe operating conditions.
Key advantages:
Non-clogging design for slurries & solids-laden fluids
Superior repeatability & accuracy
Reduced maintenance requirements
Custom bore ratio & segment height options
Compatible with all DP transmitters
Long service life in corrosive & abrasive media
Ideal alternative to concentric orifice plates in difficult applications
Designed for low pressure loss and high reliability
Working Principle – How Our Segmental Orifice Plate Works
A segmental orifice plate works on the differential pressure principle, similar to other orifice flow meters.
How it measures flow:
Fluid flows through a segment-shaped opening located at the bottom of the pipe
This creates a pressure drop across the plate
The pressure difference is measured using a DP transmitter
Flow rate is calculated using Bernoulli’s equation
Why segmental design matters
Solids and sludge pass freely through the open segment
Prevents blockage, fouling, and inaccurate readings
Ensures stable measurement in dirty services

Frequently Asked Questions (FAQs)
1. What is a Segmental Orifice Plate, and how does it work?
A segmental orifice plate is a differential pressure flow measurement device featuring a segment-shaped opening at the bottom of the pipe, which allows solids and slurries to pass through without clogging. It works by creating a pressure drop across the plate, which is measured using a DP transmitter to calculate flow rate.

2. When should a Segmental Orifice Plate be used instead of a Concentric Orifice Plate?
A segmental orifice plate should be used when the fluid contains suspended solids, viscous media, sludge, or slurry, where a Concentric Orifice Plate
may clog or give unstable readings. Segmental designs ensure reliable and repeatable flow measurement in dirty or difficult services.
3. Which industries commonly use Segmental Orifice Plates?
Segmental orifice plates are widely used in chemical plants, wastewater treatment facilities, oil & gas refineries, pulp & paper mills, sugar industries, and power plants. These industries often handle non-clean fluids, making segmental plates more effective than standard flow measurement instruments
4. What materials are available for Segmental Orifice Plates?
Asre Engineering manufactures segmental orifice plates in stainless steel (SS304, SS316, SS316L), Duplex Steel, Monel, Hastelloy, and other alloy steels, depending on the pressure, temperature, and corrosion requirements.
For high-temperature or corrosive services, we also recommend reviewing our Differential Pressure Flow Elements range.
5. Is a Segmental Orifice Plate suitable for slurry and wastewater flow measurement?
Yes, segmental orifice plates are ideal for slurry, effluent, and wastewater flow measurement because the bottom segment opening prevents sediment buildup and blockage. They are often selected over Eccentric Orifice Plates. When the solids concentration is high, flow stability is critical.
