Product features

1.4.1

Offline/parallel configuration

The instrument is fitted with a support interface (USB-C) and a Bluetooth® wireless connection (optional). Both connections
can be used to configure the instrument before process integration. After process integration, both connections can also be
used to monitor the instrument without disconnecting the communication connection.
Note: All information in this document regarding the Bluetooth® functionality of the FLEXI-FLOW™ does not apply to
instruments ordered without this functionality.
1.4.2

Instrument status (NAMUR)

With the status indication light
the NAMUR NE 107 standard. The colors provide easily recognizable signals to the operator regarding corrective actions,
malfunctions, maintenance indications, etc.
Comprehensive diagnostic information based on the NAMUR status is available in FlowSuite.
1.4.3

Multi-parameter functionality

The FLEXI-FLOW™ Compact works in much the same way as any regular digital Bronkhorst® instrument. Upon delivery, the
FLEXI-FLOW™ Compact is configured as a (mass) flow controller or meter. An integrated temperature sensor and 2 pressure
sensors provide additional real-time measurement data, allowing the main instrument function to be
flow control and pressure control
1.4.4 On-board FLUIDAT® database
A built-in database with properties of 22 commonly used gases provides the basis for up to 8 fluid presets, which can be
stored in the instrument using FlowSuite or by direct digital communication (e.g. using a custom-built (PLC) program).
The on-board FLUIDAT® conversion algorithm continuously adjusts the gas flow relative to the calibration gas, based on
the measured temperature and pressure and the properties of the
1.4.5

Multi-modular systems

The FLEXI-FLOW™ Compact can be supplied as a system with up to 8 instruments which are linked fluidically by means of a
manifold-like construction. The instruments can be controlled individually on FLOW-BUS or Modbus, or through a
42
gateway in other fieldbus systems. The gateway and the instruments behind it are powered through a single cable.
