Orifice flowmeter and balancing flowmeter are two common flow metering devices. They differ in principle, structure, and accuracy, making them suitable for different application scenarios. This article will explore the differences and advantages of these two types of flow meters, in order to help readers choose the flow meter that suits their needs

Orifice plate flowmeter is a differential pressure flowmeter based on Bernoulli's law. It creates a differential pressure by setting an orifice plate on the pipeline, causing local diffusion of fluid through the orifice plate. Based on the relationship between fluid velocity and differential pressure after diffusion, the flow rate can be calculated. The orifice plate flowmeter has a simple structure, convenient installation, and is suitable for various media, widely used in the industrial field. Its advantages lie in a wide measurement range, high accuracy, and relatively low price

In contrast, a balanced flow meter is a type of flow meter based on fluid velocity and local resistance inside the pipeline. It creates a pressure difference when the fluid flows through these local resistances by setting multiple orifice plates or cross sections with varying widths on the pipeline. By measuring the pressure difference and the resistance coefficient inside the pipeline, the flow rate can be calculated. Balanced flow meters are suitable for precise flow measurement that requires high stability and linearity, and are suitable for various media such as liquids and gases. Its advantages lie in high accuracy, good stability, and wide measurable range

In practical applications, the selection of orifice flow meters and balance flow meters depends on factors such as measurement requirements, medium properties, and cost. Orifice plate flow meters are suitable for flow measurement under most general working conditions, especially for larger flow measurement range requirements; Balanced flow meters are suitable for applications with high requirements for flow accuracy and stability, such as in industries such as petrochemicals and food manufacturing

To sum up, orifice flow meters and balance flow meters are common flow metering devices that differ in principle, structure, and application scenarios. The advantages of orifice flow meters lie in their wide measurement range, high accuracy, and relatively low price; The advantages of balanced flow meters lie in high accuracy, good stability, and wide measurable range. Choosing a suitable flow meter based on actual needs is of great significance for accurate measurement, control, and calculation of fluid flow rate. It is hoped that this article can provide readers with some reference when choosing flow timing.
