IN-FLOW Select - Industrial style (IP65)
Mass Flow Meters / Controllers for gases

General

IN-FLOW Select  Series Mass Flow Meters/Controllers are thermal mass flow meters of modular construction with a 'industrial style' pc-board housing. Control valves can either be integrally or separately mounted, to measure and control gas flows from:

  lowest range 0,014 ... 0,7 ml_n/min
  up to highest range  8 ... 1670 l_n/min

The control valve design distinguishes itself from competitive designs in its truly modular construction and it can be field replaced or changed by the user without any adjustment. The standard valve is normally closed and is available up to Kv-values of 6.0. Normally opened valves can also be supplied.

For high (differential) pressure applications, patented constructions enable us to handle high flows and/or pressures at differential pressures up to 700 bar in the IN-FLOW program, a capability which is unique in the market place. More info about high pressure mass flow meters/controllers.
