Bronkhorst UK is leader in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
IN-FLOW 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.
Full Scale capacities (N2 equivalent) versus pressure rating
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 pressure rating up to 700 bar (max. differential pressure 400 bar) in the IN-FLOW program, a capability which is unique in the market place.
All models of the IN-FLOW 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 offer great flexibility their instruments with an on-board interface with CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocol. More information about digital "multibus" communication.
As an option, IN-FLOW Mass Flow Meters and Controllers can be offered use in explosive environments. For the European market, all IN-FLOW instruments can be adapted for application in ATEX Category 3, Zone 2. For the North American market, IN-FLOW devices can be offered with FM Class I Division 2 approval, up to a pressure rating of 400 bar (5800 psi).
IN-FLOW 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, mass flow meters / controllers can be rescaled on site, saving time (and money) for mounting and dismounting. For the convenience of the user, Bronkhorst has developed an easy-to-use software tool called "FlowTune" for changing the configuration of instruments with activated Multi Gas / Multi Range option (available up to 10 bar operating pressure; to be specified at the moment of ordering).
