What is a Venturi Tube and How Does it Work?

A Venturi Tube is designed to increase the speed of flow of a fluid or gas by constricting it in a conical tube shape. When under restriction, the fluid velocity increases as it goes into the tube and decreases on the way out, which in turn produces a partial vacuum which can provide an accurate differential pressure measurement for the flow of the fluid or gas.

How big is a Venturi Tube?

Venturi tubes can be manufactured up to 180 cm or 72 inches in diameter, and can pass considerably higher flow rates than a regular orifice plate which would offer the same drop in pressure. Speak to the team at EMI today about which DP flow measurement solution is best for your requirements.

Where are Venturi Tubes used?

Venturi tubes and meters are used in the oil & gas as well as nuclear industry pipelines for measurement of differential pressure. They are also well suited to water treatment plants due to the smooth entry and exit of their conical shape. This shape can more easily allow solids and more lumpy fluids to flow through, which might get caught up and stuck at the entrance to an orifice plate.

Bypass Chamber FAQs

What is the purpose of a bypass chamber?

A bypass chamber serves as a separate channel that diverts a small portion of the fluid flow from the main pipeline, providing a controlled environment for the installation of measurement instruments. It allows for accurate monitoring and measurement without interrupting the primary flow.

How do I choose the right size of a bypass chamber for my application?

The size of the bypass chamber depends on factors such as the flow rate, pipe diameter, and desired accuracy. Our engineering team can assist you in selecting the appropriate size based on your specific application requirements, ensuring optimal performance and accurate measurements.

What materials are available for bypass chambers?

We offer a wide range of materials for bypass chambers, including stainless steel, brass, and various alloys.
