Pneumatic Pulse Counters

The Viridian pneumatic pulse flow counter works with any pneumatic pump to give an indication of the total volume discharged from the pump.

The pulse flow counter comprises a magnetically actuated mechanical counter and a spring return piston housing a magnet. The displacement of the piston is proportional to air flow rate. The external mechanical counter should be positioned relative to the displacement of the piston. As the magnet within the piston sweeps past the mechanical counter, it registers one count. The pulse flow counter should be fed with dry, filtered air down to 20 microns.
