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 offer great flexibility thanks to the “multibus” concept, whereby the instruments can be equipped with an on-board interface with DeviceNet™, PROFIBUS DP, Modbus, PROFINET, 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 has developed an easy-to-use software tool called “FlowTune” for changing the configuration of Select instruments with activated Multi Fluid / Multi Range option (available up to 10 bar operating pressure; to be specified at the moment of ordering).
