Orifice Plate Flow Meter A reliable technology for precise fluid measurement

In modern industrial production and scientific research, accurate measurement of fluid flow is crucial. Whether in petrochemicals, power energy, pharmaceuticals, food, or numerous other fields, the accuracy and reliability of flow measurement directly affect production process control, quality assurance, and cost control. Among the many flow measurement technologies, Orifice Plate Flow Meter it has become a reliable choice for precise fluid measurement due to its unique advantages. Alita As a well-known brand in the industry, its orifice plate flow meters have secured a significant market position due to their superior performance and quality.

I. Working Principle of Orifice Plate Flow Meter

The working principle of the orifice plate flow meter is based on the Bernoulli equation and the continuity equation. When fluid flows through the orifice plate, the flow velocity increases and the pressure decreases due to the sudden reduction in the flow area. By measuring the pressure difference before and after the orifice plate and combining the known fluid physical parameters and the geometric dimensions of the orifice plate, the fluid flow rate can be calculated.

The orifice plate is usually a thin plate with a central circular hole, installed in the pipe so that it is perpendicular to the pipe axis. When the fluid passes through the orifice plate, a pressure difference is generated upstream and downstream of the orifice plate, and this pressure difference is proportional to the fluid flow rate. By connecting pressure sensors before and after the orifice plate, the pressure difference can be accurately measured and converted into a flow signal.
