Venturi Tubes & Nozzles
From welded to machined designs, our Venturi solutions deliver reliable flow measurement with reduced installation costs and maintenance.
Venturi tubes and nozzles are DP flow elements that measure fluid velocity via a controlled pressure drop. Tubes feature a tapered inlet, narrow throat, and diverging outlet for high-pressure recovery and low loss, ideal for clean liquids, gases, wet gas, and CO₂. Venturi nozzles combine a nozzle’s converging section with a Venturi outlet, handling high-velocity, erosive flows like steam. More information on these elements and Endress+Hauser’s offerings can be found below.
Benefits
- Venturi Tubes
• Produces a high level of accuracy in readings
• Low maintenance and pressure loss due to no moving components of the tube
• Available in wide size ranges and is suitable for a range of different fluids and industrial applications - Venturi Nozzles
• Improved pressure recovery and reduced permanent pressure loss
• Durable design with no sharp edges meaning minimal wear and low maintenance costs
• Suitable for a large variety of pipe sizes and layouts, as well as harsh media
Venturi Tube
A Venturi tube is a DP flow element that measures fluid flow by gradually narrowing the pipe to accelerate the fluid and then expanding it to recover pressure, creating a predictable pressure drop proportional to flow rate. Venturi tubes use the Venturi effect which is the reduction of fluid pressure that results when a fluid runs through a constricted section of pipe. These meters are effective and create less pressure loss than orifice plates.
Venturi Nozzle
Venturi nozzles combine the best features of a Venturi tube, and a flow nozzle combined into a singular unit. They excel when used with erosive fluids, high velocity flow rates and/or non-viscous fluids. Similarly to the venturi tube, these meters create low pressure loss in comparison to other DP flow elements.
