ST2 Stack velocity and flowrate
Stack velocity and flowrate
ST2
ST2 is a velocity and flow meter for chimneys able to work with all Pitot tubes available on the market.
ST2 is a unique instrument of its kind and the result of a development aimed at creating a solution that allows, at the same time, to simplify the evaluation of fluid-dynamic stack conditions but which also has reduced dimensions and weight, to limit the overall dimensions. in transport and, above all, in altitude.
