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. More
info about high pressure mass flow meters/controllers.

Digital = Standard

All models of the EL-FLOW Select series are equipped with a digital
pc-board, featuring self-diagnostics, alarm and counter functions, digital
communication (RS232) and remotely adjustable control settings. These digital
instruments from Bronkhorst High-Tech offer great flexibility thanks to
the “multibus” concept, whereby the instruments can be equipped with an
on-board interface with DeviceNet™, PROFIBUS DP, Modbus, EtherCAT®
(MBC3 pcb required) or FLOW-BUS protocol. More
information about digital “multibus” communication.

Optional Multi Gas / Multi Range

EL-FLOW Select instruments can be offered with optional Multi
Gas / Multi Range (MG/MR)
 functionality. This option offers greater
flexibility for user selection of both flow ranges and gas types, maintaining
high accuracy and turndown range for measurement and control. Thanks hereto,
users of these instruments can rescale their instruments on site, saving
time (and money) for mounting and dismounting. For the convenience of the
user, Bronkhorst High-Tech has developed an easy-to-use software tool called
“FlowTune” for changing the configuration of Select instruments with activated
Multi Fluid / Multi Range option (to be specified at the moment of ordering).
