WIKA A2G-25 Series Air flow meter Flow Meter for Air

The Wika A2G-25 air flow meter is used for measuring air flows of gaseous media in ventilation and air-conditioning applications. The air flow is measured by determining the differential pressure and multiplying it with the K factor. The K factor depends on the ventilator used or, when using pipe/duct measuring probes, on the size and number of probes and is easy and fast to enter in the menu. The different calculation formulas for the air flow are already programmed in the menu of the A2G-25. By choosing the respective radial ventilator manufacturer, the correct formula is automatically taken into account in the calculation.
