Paddle/Flap/Target/Vane Flow Meter and Switches Products

Paddle, flap, target, and vane flow meters belong to a category of mechanical flow meters that measure the flow rate by the force exerted on a known area by the flowing media. These meters are straightforward in design and operation, making them suitable for a wide range of applications, including water treatment, HVAC, and industrial processes. They are particularly useful for measuring flow in large pipes and ducts where other types of flow meters may not be practical or cost-effective.

These devices offer the advantage of being able to measure flow in both clean and dirty fluids. The simplicity of their design translates to ease of installation and low maintenance, with the mechanical nature of the measurement providing a robust and reliable method for flow monitoring. While they may not offer the precision of some advanced flow meters, paddle/flap/target/vane flow meters provide a valuable solution for applications where simplicity and durability are key considerations.
