With analogue output signal (0 … 10 V or 4 … 20 mA) or MODBUS ® protocol Output signal for air flow and differential pressure in one instrument Simple and fast mounting and commissioning Maintenance-free Maximum operating pressure 20 kPa

The model 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. Electrical analogue output signals for both measurands (DC 0 … 10 V or 4 … 20 mA) or the digital Modbus ® versions enable the direct connection to control systems or the building automation system. The measured differential pressure is also shown on the LC display and transmitted via the analogue or digital output signals. Thus the A2G-25 combines two measurements in one instrument. The LC display and the clear menu navigation enable a time-saving and simple commissioning. With the A2G-25, air flows up to 200,000 m3/h and differential pressures up to 7,000 Pa can be measured.

In addition to A2G-25, Glorient also supplies:
