The QVT allows for precise and accurate air flow measurement of differential pressure from 9 in WC down to 0.0009 in WC and allows for the measurement of up to 4 variables at once, including Differential Pressure, Absolute Pressure and Process Temperature. The QVT will output a 4-20 mA signal corresponding to Differential Pressure or Flow.
