Venturi Tube FL60
The Venturi Tube FL60 is an advanced device used for measuring fluid flow based on pressure difference. This device is widely used in various industries for measuring the flow of liquids and gases due to its unique design. Unlike orifice plates, the Venturi tube avoids issues like excessive pressure loss and blockage due to debris. These unique features and its performance make the FL60 Venturi Tube one of the most widely used tools in industrial processes.
How it works
In the FL60 Venturi tube, fluid flows through a conical tube that first has a converging section, followed by a throat section. After the throat, the fluid enters the diverging part of the tube. This design creates a pressure difference at different points in the tube, which can be used to calculate the flow rate. Due to pressure recovery in the diverging section, the output pressure is much closer to the inlet pressure, minimizing permanent pressure loss.
Main Components
- Converging Section: The initial part that increases the fluid’s velocity and reduces its pressure.
- Throat: The point where the fluid reaches its highest velocity and lowest pressure.
- Diverging Section: The final section where pressure recovery occurs.
- Pressure Tappings: For measuring pressure difference at different points in the tube.
- Body: Made from materials resistant to corrosion and high pressure.
Advantages of using Venturi Tube FL60
- Minimized pressure loss: Special design that minimizes permanent pressure loss.
- Stable performance: Suitable for steady flow and fluids with suspended particles.
- High accuracy: Accurate flow measurements with minimal error.
