1. Introduction SwemaMan 7 is a micro manometer for differential pressure, air flow and air velocity. Differential pressure is measured in Pa, airflow in l/s, m3/h or CFM and air velocity in m/s or fpm. It’s possible to set baro- metric pressure and temperature to compensate for correct air density. -
