Description
The model A2G-FM measuring probe measures air velocities and air flows in ventilation and air-conditioning systems. The intelligent design makes for a very easy installation in existing ventilation pipes and ducts.
The A2G-FM measuring probe has 4 … 12 openings (holes) on each side. The differential pressure openings on the front and back side are separated from each other by design and form two pressure chambers. The length of the measuring probe determines the number of openings. A dynamic overpressure is created at the front of the measuring probe. The pressures applied to the differential pressure openings are averaged. They are then fed through to the volumetric flow meter via separate hose connections.
The averaging function enables the probe to better correct interfered flow profiles which occur many times in the air duct network. The unique shape of the probe enables measurement even at very low air velocities of down to 1.0 m/s.
The measuring probe is available in two different versions, depending on the requirements and the installation situation. The version R is used for circular ventilation pipes and the version L for rectangular ventilation ducts.
