What is Orifice Plate?
Orifice plates serve as the predominant primary devices for measuring flow in pipelines by relying on the ‘Differential Pressure’ principle. This principle involves measuring the pressure difference generated when an obstruction is introduced into the fluid flow, resulting from an increase in fluid velocity. Orifice plates are versatile and applicable across a broad spectrum of fluid and operating conditions. They provide a satisfactory level of precision at a minimal cost and offer long-term durability without the need for frequent maintenance.

Types of Orifice Plates manufactured by Arrotop
Orifice plates come in various types like concentric, eccentric, segmental, conical and square edged. Each is designed for specific fluids and flow conditions to ensure accurate and efficient flow measurement across diverse industrial applications.
A concentric orifice plate ensures high accuracy and is ideal for clean liquids, gases, and steam, offering the lowest uncertainty in flow measurement.
Eccentric orifice plates, with an off-center bore, offer accurate and reliable flow measurement, especially for fluids with solids or entrained gases.
Segmental Orifice Plate, with a segment-shaped bore, ensures accurate flow measurement of fluids with solids, vapors, or condensates.
Quarter circle orifice plates feature a rounded inlet, combining orifice and nozzle benefits for accurate flow measurement in viscous or low Reynolds fluids.
Multi-hole orifice plates, with 4 radially placed bores, enhance flow measurement accuracy and stability in systems using square edge, eccentric, or segmental types.
Conical entrance orifice plates ensure precise flow measurement in pipelines, widely used in oil and gas industries for accurate oil and gas flow monitoring.
Restriction orifice plates reduce flow and pressure to protect downstream equipment and minimize noise, ensuring safe and efficient system operation.
Square-edged concentric orifice plates measure bidirectional flow with precision, using a straight central hole machined into a thin metal plate.
RTJ orifice plates with integral oval/octagonal gaskets suit high-temp, high-pressure flows; ideal for clean liquids, gases, and low-velocity steam.
