Rotameter Description
Rotameters, also known as float flow meters, are a commonly used variable-area flowmeter. They primarily consist of a tapered measuring tube and a float. As fluid flows upward through the tube, the float rises due to the combined effects of fluid dynamics and gravity. The float’s equilibrium position corresponds to the scale on the tube wall, indicating the current flow rate.
Operating Principle
As fluid flows through the tube, the increased flow velocity and pressure differential push the float upward.
When the upward thrust of the fluid balances the float’s weight, the float stabilizes at a certain height.
The flow rate can be read by observing the scale corresponding to the float’s position.
Key Features
Simple Structure: No complex drive components, intuitive and reliable mechanical readings.
Adaptable: Suitable for measuring the flow of liquids or gases.
Easy Installation: Typically installed vertically, with fluid flowing from bottom to top.
Direct Reading: Flow rate can be read directly without a power source.
Material Options: The measuring tube and float can be made of plexiglass, stainless steel, or corrosion-resistant plastic to accommodate different media.
Applications in PCB Equipment
Cooling Water System: Monitors cooling water flow in equipment, ensuring stable temperature control and preventing overheating.
Compressed Air Piping: Monitors airflow to ensure proper operation of nozzles, air knives, and other process steps.
Chemical Liquid Distribution: Provides simple and intuitive flow monitoring in some auxiliary chemical or cleaning fluid pipelines.
To provide high-precision, high-performance PCB equipment accessories, empowering the global electronics manufacturing industry to achieve efficient production.
