Structure and Operating Principle

Main Components

The Vortex Flowmeter PRE7200 Series is composed of several essential parts:

• Housing: Protects the internal components and ensures durability.
• Vortex Generator: Creates vortices proportional to the flow rate.
• Flow Sensor: Measures the frequency of vortices to determine flow rate.
