1. Product Summary
The ASAIR AFD4 series is a water flow sensor based on the Karman vortex principle. Under certain conditions, when a fluid with a certain volume flow flows around the spoiler, two linear vortices with opposite rotation direction and regular arrangement will periodically form on both sides of the spoiler column, forming Karman vortex street. Sensors measure the flow of liquid through the pipe by sensing how fast or slow the vortex is flowing through the internal chip. With long service life, resistance to contamination, high accuracy, fast response and no drift, the sensors are ideal for demanding and cost-sensitive OEM applications.
2. Key Features
• Good repeatability, high accuracy
• Low pressure loss, pollution resistance
• Vortex measurement principle
3. Applications
The AFD4 series flowmeters provide multi-functional sensing solutions for harsh industrial production environments, energy metering, environmental protection, laboratory environments, transportation and other application scenarios.
