Badger Venturi Tubes
Badger Venturi Tubes
Features
- High Accuracy
- Reliable Operation
- Energy Efficient (Low Headloss)
- Different Options for a Variety of Applications
Description
The Badger Venturi Tube (BVT) is a primary flow element that accurately and repeatably measures the flows of liquids or gases in closed, full-pipe conditions. The BVT incorporates an efficient hydraulic shape with static pressure taps in the throat and inlet section. The BVT can be provided with either flanged or plain end connections. Wyatt offers full body pressure vessels and insert-type flow elements.
Applications
The BVT elements are often used in applications where the flow stream demands a specific material selection due to temperature and/or pressure, or the corrosive/erosive properties of the fluid being measured. BVT installations are found in power plants, refineries, chemical plants, cryogenic processes, water and sewage plants, custody transfer for steam and billing measurements.
Technical Specifications
Accuracy:
For pipe Reynolds numbers greater than 75,000 and a normalized piping configuration, the Wyatt Badger Venturi Tube provides a flow measurement uncertainty of:
± 0.50% for standard meters without flow calibration, and± 0.25% for flow calibrated meters.
Pressure Loss:
The permanent pressure loss of the Badger Venturi Tube.
Beta Ratio:
Badger Venturi Tubes are available with a wide range of diameter ratios (d/D). This provides users with an accurate flow measurement over a broad range of flow rates for a given line size and set of process conditions.
Temperature Range:
Depending on the material of construction, the Badger Venturi Tube can operate over a fluid temperature range of -425 °F to +1,200 °F (-250 °C and +650 °C).
Piping Requirements:
Designed for full-pipe flow, Badger Venturi Tubes may be mounted either horizontally or vertically. For recommended upstream piping, refer to Wyatt Engineering BVT TECHspec.
Energy Considerations
The headloss of the BVT design with that of other primary flow elements. The pressure recovery of the Badger Venturi Tube means reduced pumping costs. Wyatt venturis have a shorter laying length and exhibit better recovery than typical classical and modified venturi meters.
The Wyatt Venturi is designed to provide a high degree of accuracy with unquestionable and predictable performance. Key to this design is the following:
Accuracy: Static inlet and throat pressure sensation provides a highly accurate, stable, and predictable flow measurement signal for flow rates with pipe Reynolds numbers as low as 75,000.
Reliability: Wyatt Venturi Tubes are free of protrusions and sharp-edged, debris-collecting annuli. Static pressure taps reduce flow noise. The internal contour is designed to minimize the buildup of solids and deter erosion, corrosion, and scaling.
Energy Savings: Wyatt Venturi Tubes operate with minimal headloss. This results in less energy consumption, lower operational costs, and a lower cost of ownership.
