Preso® Ellipse® modèle BAR (annulaire, commercial)

The Preso Ellipse BAR (annular, commercial) is a multipoint averaged differential pressure flow element. It features a two-piece design, an elliptical shape with two fully independent flow detection chambers to prevent signal degradation or interference, or the use of moderating software or hardware. Impact velocity detection orifices are located along the front edge, while those capturing real static pressure are on the probe's external side. The probe generates no swirl or vacuum effect that could intrude on the static pressure measurement zone and has a drag coefficient of 0.32 or less. Each flow sensor comes with an instrumentation isolation valve and allows the installation of a transmitter or direct indication counter. A station-specific flow measurement data identification label is provided as needed.

• No separation effect for low static pressure: Maintains accurate readings even at low pressures
• High variation ratio of 17:1: Covers a wide range of flow rates
• No vacuum effect: Ensures stable performance in various conditions
• No vortex generation: Minimizes measurement errors
• Very high repeatability: Consistent and reliable readings over time
• Lowest drag coefficient: Optimizes flow and reduces energy loss
