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

General

IN-FLOW Select  Series Mass Flow Meters/Controllers are thermal, bypass-type, 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 mln/min
up to highest range  8 ... 1670 ln/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.

Digital = Standard

All models of the IN-FLOW Select series are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication 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 DeviceNetTM, Profibus-DP®, Modbus-RTU or FLOW-BUS protocol. More information about digital "multibus" communication.

Optional Multi Gas / Multi Range

These new instruments with Multi Gas / Multi Range (MG/MR) functionality offer greater flexibility for user selection of both flow ranges and gas types, maintaining high accuracy and turndown range for measurement and control. Thanks to this feature users of the Select series 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).
