GAS Mass Flow Meters / Mass Flow Controllers

EL-FLOW® Select Series Mass Flow Meters/Controllers are thermal mass flow meters of modular construction with a ‘laboratory 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 mln/min up to highest range 8…1670 ln/min. The control valve design of the mass flow controller distinguishes itself from competitive designs by its truly modular construction and its ability to 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 1.5. 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 400 bar in the EL-FLOW® program, a capability which is unique in the market place.
