With the increasing awareness of environmental protection and the continuous improvement of environmental regulations, the environmental protection field has put forward higher requirements for the accuracy and reliability of flow measurement. Orifice Plate Flow Meter As a classic flow measurement instrument, it has been widely used in the environmental protection field due to its simple structure, accurate measurement, and strong adaptability. This article will take you to Orifice Plate Flow Meter manufacturer to gain an in-depth understanding of its flow measurement needs and solutions in the environmental protection field.

Basic Principles and Characteristics of Orifice Plate Flow Meters

Orifice plate flow meters are flow measurement instruments designed based on Bernoulli's equation and the fluid continuity equation. Their basic principle is to install an orifice plate with an aperture in the pipeline. When the fluid flows through the orifice plate, it will cause local contraction, increasing the flow velocity and decreasing the static pressure. By measuring the pressure difference before and after the orifice plate, the flow rate of the fluid can be calculated.

The main characteristics of orifice plate flow meters include:

1. Simple Structure : Mainly composed of an orifice plate and a pressure tapping device, it is easy to install and maintain.
2. Accurate Measurement : Under standard conditions, the measurement accuracy can reach ±1%.
