Introduction
A rotary pump is a positive displacement pump that moves fluid by rotating one or more internal elements, such as gears, lobes, screws, or vanes. Unlike centrifugal pumps, rotary pumps deliver a steady, non-pulsating flow regardless of discharge pressure, making them ideal for high-viscosity fluids and applications requiring precise flow control. This article covers the working principle, key features, advantages, disadvantages, and applications of rotary pumps.

Introduction
The jet pump is a fluid-handling device that uses the Venturi effect to move fluids without any moving parts. Driven by a high-pressure working fluid, it creates a vacuum to draw in and transport another fluid. Its simple, reliable design makes it ideal for handling challenging fluids like slurries and corrosive chemicals, though it operates at lower efficiency than mechanical pumps. This article covers its working principle, key features, advantages, disadvantages, and applications.

IntroductionThe vortex flowmeter is a volumetric flowmeter that measures the volumetric flow rate (actual, standard, or mass) of gases, vapors, or liquids based on the von Kármán vortex street principle. It can also function as a flow transmitter within automated control systems.

Abstract
Turbine flow meters form the cornerstone of industrial flow measurement technology, and are particularly valued for their rapid response, wide rangeability, and low pressure loss in clean liquid and gas applications. This article mainly discusses the working principle of turbine flow meters, measurable and non-measurable media, advantages, and application industries.

Introduction
The Type D horizontal multistage centrifugal pump features high efficiency, a wide performance range, safe and stable operation, low noise, long service life, and ease of installation and maintenance; it is suitable for transporting clean water or other liquids with physical and chemical properties similar to water. By modifying the materials of the flow-path components and the sealing method, or by adding a cooling system, it can also be used to transport hot water, oil, or corrosive or abrasive media.

Introduction：
A pressure sensor is a device that converts pressure signals into electrical signals. It is widely used in industrial control, medical equipment, and automotive electronics. Its core principle is based on the piezoresistive or capacitive effect, and it features fast response and high accuracy, making it a key component in modern intelligent sensing systems.
