The DF-231BA is equipped with a highly responsive (99% response 300ms) mass flow sensor. It can handle extensive flow ranges from 500mL/min to 500L/min. The DF-231BA also comes with a multi-function indicator that is idea for various measurements so you won’t have to correct temperature and/or pressure changes.
