1. to Orifice Plate Flowmeter: Behind the Elegant Design

Orifice Plate Flowmeter is an instrument that measures flow through the pressure difference generated when fluid passes through an orifice plate. Its main components include a circular or square orifice plate. When the fluid passes through the orifice plate, a pressure difference is generated. The flow rate of the fluid is calculated by measuring this difference. Its design is simple and easy to operate, and it is widely used in flow measurement of liquids and gases.

2. Working principle: the secret of fluid passing through the orifice plate

The working principle of the orifice plate flowmeter is based on Bernoulli's equation and the continuity equation. When the fluid passes through the orifice plate, the velocity increases and the pressure decreases, forming a local vacuum area. By measuring the pressure difference between upstream and downstream, the flow rate of the fluid can be calculated. The schematic diagram clearly shows the entire process of fluid passing through the orifice plate.
