The DF-100HD Series heavy duty portable flow meter upgrade kits are designed to upgrade existing low volume analog air sampling systems utilizing motors of 1/3 HP or less. The DF-100HD Series units are connected in-line between the pump inlet and the filter holder. The DF-100HD Series upgrade eliminates the need to engage in expensive conversions of equipment or the need to purchase new air sampling systems.
The typical maximum operating flow ranges vary from 1 CFM to 9 CFM (30 – 255 LPM). Custom higher flow ranges with exterior mounted flow sensors are available upon request.
