Use & Benefits for Orifice Plates:

Flow Measurement: They measure fluid flow rate in pipelines. By constricting the flow path to create a pressure drop, flow rate can be measured using Bernoulli’s equation.

Cost-Effective: Simple, inexpensive, and reliable compared to other flow devices.

Easy Installation & Maintenance: Easily integrated into pipelines with minimal upkeep and quick replacement.

Wide Compatibility: Suitable for liquids, gases, and steam across industries like oil & gas, chemical processing, water treatment, and HVAC.

Standardized Design: Meets API and ISO guidelines for consistency and reliability.
