EX-FLOW® Mass Flow Meters/Controllers

    The flow meters/controllers of the EX-FLOW series are thermal mass flow meters/ controllers in rugged construction for use in hazardous areas. The sensor is PTB or CENELEC tested and approved under number PTB Ex-88.B.2103, protection EEx ib IIC T4.   The characteristic properties of Bronkhorst Hi-Tec mass flow meters/controllers are also found in the ex-proof instruments: (no moving parts; short response time; no need for flow computer; temperature and pressure measurement; low pressure drop; pressure ratings up to 400 bar).  Lowest range   0,2…10 mln/min.   Highest range   220…11.000 mln/min.
