For ventilation and air-conditioning


  • For measuring the air flows of radial ventilators
  • For measuring air flows in ventilation pipes and ducts in conjunction with the model A2G-FM measuring probe
  • Measurement of differential pressures

Special features

  • 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.

      #Dial#thermometers work on the #bimetal, #expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring location design.#Dialthermometers with remote capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.
