1.4 Product features
1.4.1 Configuration via USB-C or Bluetooth
Support interface (USB-C)
The support interface can be used to configure and/or monitor the instrument in its operating environment, without
the need to disconnect the power supply and fieldbus connection.
At the same time, the power supply on the USB connection is sufficient to allow configuration of the instrument before it is
integrated in the process environment.
Bluetooth
The instrument can be configured via a wireless Bluetooth connection, again without the need to disconnect the power
and fieldbus connection.
The required power can be supplied through the power connector or the USB-C- connector.
The FLEXI-FLOW™ Compact is delivered with Bluetooth disabled; it can be enabled using FlowSuite.
· For operation, the instrument always needs to be powered through the power connector.
· Bluetooth configuration requires powering the instrument through the power connector or support interface.
· To minimize heat build-up in the instrument, it is recommended to keep the support interface connected only when
needed for configuration and/or monitoring purposes.
1.4.2 Instrument status (NAMUR)
With the status indication light , the FLEXI-FLOW™ Compact shows its current status , using a color range based on
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. An integrated temperature sensor and 2 pressure sensors
provide additional real-time measurement data, allowing the main instrument function to be switched between 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 a custom-built (PLC) program.
A compensation algorithm (FLUIDAT® On Board) continuously adjusts the gas flow based on the currently measured
temperature and pressure and the properties of the selected gas (mixture).
1.4.5 Multi-modular systems
The FLEXI-FLOW™ Compact can be supplied as a system with up to 8 modules which are linked fluidically by means of a
manifold-like construction. The modules can be controlled individually on FLOW-BUS or Modbus, or through a gateway
in other fieldbus systems. The gateway and the instruments behind it are powered through a single cable.
For information about FLEXI-FLOW™ Compact based multi-modular systems and possible applications, contact your
Bronkhorst representative.
1.4.6 Default valve state
When a controlling instrument is not powered or cannot communicate with the fieldbus network (if applicable), all electrical
valves operated by the instrument (whether integrated or external) automatically return to their default state. The default
state is closed for 'normally closed' valves (n/c) and fully open for 'normally open' valves (n/o). Taking into account the
typical process conditions under which the instrument is used (such as the processed media and ambient conditions; see
also Intended use ), the default state is generally considered safe.
Check the serial number label or the technical specifications to see which valve type is used on your instrument (if
applicable).

2Installation
2.1 Product specifications
Before installing the FLEXI-FLOW™, check that the functional and technical properties of the
product match your requirements (the image on the right is an example; it does not necessarily
reflect the actual specifications of your instrument).
If you have a question about the product or if you find the product does not meet the
specifications as ordered, do not hesitate to contact your Bronkhorst representative (see the first
pages of this document). To enable us to help you quickly and effectively, have the serial number
ready whenever seeking contact with your Bronkhorst representative about a specific item. The
serial number is the key to the original purchase order and can be found on the serial number
label, in the instrument properties in FlowSuite and by reading the according digital parameter
(see parameter section Device identification ).
2.1.1 Pressure rating
At the factory the FLEXI-FLOW™ has been pressure tested and tested with helium for outboard leakage. The test pressure
includes a safety factor, so that it is always higher than the specified maximum operating pressure (pressure rating).
· The test pressure is specified with a red label; if this label is missing, the device must not be
used and should be returned to the factory.
· Before installation, make sure that the pressure rating is within the limits of the normal
process conditions of your application.
2.2 Mounting
For optimal performance, observe the following guidelines:
· Avoid installation in close proximity of mechanical vibration and/or heat sources.
· Use the equipment in an environment with a stable ambient pressure and
temperature.
· For stable fixation to a rigid and stable surface or construction, use the threaded
mounting holes in the bottom of the instrument base. Consult the dimensional
drawing for the exact size and locations.
2.2.1 Piping requirements
· For reliable performance, make sure the fluid stream is uncontaminated. If necessary, use an inlet filter to ensure a
particle free media stream. Select a filter with a maximum pore size of 20 µm and a surface area that minimizes the
pressure drop.
· If back flow could occur, the use of a check valve is also recommended.
Use piping or tubing that is suitable for the operating conditions of the application (media, maximum temperature,
maximum operating pressure).
2.2.2 Fluid connection
· Connect the FLEXI-FLOW™ to the fluid system in accordance with the product overview .
· Tighten fluid connections according to the instructions of the manufacturer of the fittings. The use of Swagelok® RS-type
stainless steel adapters is recommended.
· Make sure connector sizes match; do not mix metric (mm) and imperial (inch) sizes.
· Make sure all connectors and tubing are free from dirt and debris.
Instructions for connecting and disconnecting Swagelok® fittings can be found in the Installer's Pocket Guide for Swagelok®
Tube Fittings (doc. no MS-13-151)

Check the fluid system for leak tightness after any modification and before applying full operating pressure, especially when
using hazardous media (e.g. toxic or flammable).
2.2.3 Preventing pressure shocks
FLEXI-FLOW™ instruments can handle pressure shocks in the system well, but are not insensitive to pressure fluctuations.
For optimal control stability, observe the following guidelines:
· Provide a stable (pressure controlled) inlet pressure; put sufficient buffer volume between the pressure regulator and the
instrument. As a rule of thumb, install pressure regulators at a distance of at least 25 times the pipe diameter from the
inlet or outlet of the instrument.
· When using multiple instruments and/or control valves, prevent interference by putting piping with sufficient buffer
volume between components.
2.3 Electrical connection
· Electrical connections should be made according to the hook-up diagram , using the supplied cables (insofar as
included) or compatible, with respect to required supply current, voltage loss, cable length, cable and gland diameters
and operating conditions.
· When using self-assembled cables, follow the guidelines provided by the connectors' manufacturer.
· For use in a fieldbus system, follow the instructions of the cable supplier for the according fieldbus system.
· Make sure that the power supply matches the power rating of the instrument (see technical specifications ) and that
double or reinforced insulation is used for the power supply.
· If a surge protection device is used, make sure its specifications match the power consumption of the application.
To prevent damage as a result of reversed polarity, the use of a 2A fuse in the direct +Us line is recommended.
Always turn off electrical power before connecting or disconnecting equipment electrically.
In order to be able to comply with all applicable guidelines and regulations, it is essential that electrical connections be
made by or under supervision of a qualified electrician.
· The equipment described in this document contains electronic components that are susceptible to electrostatic
discharge.
· When working on the electrical installation, take appropriate measures to prevent damage as a result of electrostatic
discharge.
The CE mark on the equipment indicates that it complies with requirements imposed by the European Union, including
electromagnetic compatibility (EMC).
EMC can only be guaranteed by applying appropriate cables and connectors or gland assemblies:
· Cable wire diameters must be sufficient to carry the supply current and minimize voltage loss.
· When connecting the product to other devices, ensure that the integrity of the shielding remains uncompromised; use
shielded cables and connectors where possible and/or required.
· Preferably use the supplied cables (if applicable) to make electrical (signal) connections to and between the supplied
components. These cables are shielded, have the required wire diameter, and loose ends (if applicable) are marked to
facilitate correct connection.
If not all requirements for proper shielding can be met (for example, because a component is not equipped with shielded
connectors), take the following measures to ensure the best possible shielding:
· Keep cable lengths at a minimum.
· Route cables as closely as possible alongside metal structures or components.
· Ensure all electrical components are grounded to earth.
When in doubt about the shielding of your cabling and/or electrical connections, contact your Bronkhorst representative.

3Operation
3.1 General procedures
Before operating the FLEXI-FLOW™, make sure that the equipment has been installed and configured by an authorized
engineer and that the installation is approved for use.
To ensure and maintain a safe working area, regularly inspect electrical and fluid lines and connections:
· Prior to each use, check cabling for proper connection, damage and wear. If necessary, replace cables and/or connectors.
· Before, during and after operation, check fluid lines and connections for leaks, damage and wear. Re-tighten fluid
connections as necessary, replace connectors as needed.
During operation, fluid connections may not be loosened or disconnected under any circumstances.
Gas condensation in the instrument can seriously affect its performance and reliability.
· If possible, ensure that the ambient temperature is stable and at least equal to the temperature of the process gas.
· Always use a clean and dry process gas (preferably with a purity of at least 99.5 %).
3.1.1 Powering up
To maintain control of the fluid system and ensure a safe situation, it is recommended to turn on power before applying
fluid pressure and to switch off power only after the fluid system is depressurized.
When pressurizing, prevent pressure shocks by gradually bringing the fluid system to the required operating pressure.
· When powering up, the instrument needs a couple of seconds to start up the electronics and perform a self-test.
· During initialization, the indication light cycles through all NAMUR status colors .
· After successful initialization, the indication light lights up green to indicate that the instrument is ready to be used.
3.1.2 First use
Bronkhorst does the utmost to ensure that you receive a clean product. This does not, however, relieve the user of the
responsibility to ensure that the equipment and the system in which it is incorporated meet the requirements implied by
the intended use of the product. The responsibility for cleaning the equipment to meet such requirements lies exclusively
with the user.
3.1.3 After use
· Depending on the properties of the process medium and the (expected) time until the next use, it is advisable to flush the
fluid system with a suitable (cleaning) fluid after use.
· If the equipment has been used to process corrosive, reactive or hazardous media (e.g. toxic or flammable), cleaning the
fluid system is imperative before it is exposed to air.
· If the equipment is not used for an extended period, the fluid system should be dry after use and after cleaning. If not, it
should be purged with a dry, inert gas for a recommended minimum period of 30 minutes.
3.1.4 Powering down
· Prior to powering down the FLEXI-FLOW™, the fluid system should be depressurized.
· When depressurizing, prevent pressure shocks by shutting off the fluid supply gradually.
3.1.5 Understanding instrument status
The status indication light uses different colors to reflect the current status of the instrument:
Green

Bronkhorst®
Instruction Manual FLEXI-FLOW™ Compact9.17.158A 15
· The colors are based on the NAMUR NE 107 standard and are a simplified representation of the instrument's diagnostic
data .
· After powering up or restarting the instrument, the indication light cycles through all status colors once.
· After the startup cycle, the indication lights assumes the color associated with the current instrument status.
Bluetooth
· When Bluetooth is active, the indication light flashes blue once every 3 seconds.
· If the instrument has a Bluetooth connection, the indication light flashes blue twice every 3 seconds.
· Bluetooth communication is not reflected by the indication light.
· Bluetooth indications are not related to the blue NAMUR indication.
Zeroing
· During zero point adjustment , the indication light blinks blue (1 second on, 1 second off).
· The zeroing indication is not related to the blue NAMUR indication.
3.2 Special procedures
3.2.1 Address selection
Manual address selection
Assuming the default baud rate and parity match the fieldbus settings, the fieldbus address can be quickly set using the
manual address selector :
· With value 0, the instrument uses the digital address setting
· Values from 1 to 9 override the digital setting
Digital network settings
FlowSuite can be used to set the fieldbus address, baud rate and parity digitally (through the support interface or with
Bluetooth). This can even be done before connecting the instrument to the fieldbus.
See also parameter section Network configuration for digital parameter settings and default values.
· A USB connection on the support interface provides sufficient power for instrument configuration only.
· Bluetooth configuration requires powering the instrument through the power connector or support interface.
3.2.2 Switching control function
Communication channels
The so called multi-parameter functionality enables simultaneous measurement of flow, inlet pressure and outlet pressure,
using 3 different communication channels:
Communication
channel
Measurement and control variable
1
Flow (F)
2
Inlet/upstream pressure (P1)
3
Outlet/downstream pressure (P2)
17
16
7
27

Bronkhorst®
Instruction Manual FLEXI-FLOW™ Compact 9.17.158A16
· Channel 1 is the main communication channel, providing all parameters for normal operation of the FLEXI-FLOW™
Compact as a regular flow controller.
· Channels 2 and 3 provide access to additional pressure measurement and control features, as well as alarm definitions.
· Bronkhorst® software automatically adds the additional communication channels to the array as regular instruments.
Switching control function
· A setpoint can be given on any of the 3 communication channels. However, the instrument uses only one setpoint at any
given time.
· Use parameter Control Function to set the main instrument function (flow controller or pressure controller).
· See section Multi-parameter addressing for available parameters.
3.2.3 Enabling Bluetooth
· Bluetooth can be enabled using FlowSuite.
· When pairing the instrument can be recognized by its serial number.
· The first time the instrument is paired with FlowSuite, a six-digit passkey must be created.
· Subsequently, the instrument can only be paired by entering the passkey that is stored in the instrument.
3.2.4 Adjusting zero point
Zero-stability
The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is
factory adjusted at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned
upright. Under normal circumstances (i.e. at stable process conditions), the zero point will remain stable. However, over time
several factors can induce a slight deviation of the measured value from the zero point, causing the instrument to detect a
flow when in reality there is none. Readjusting the zero point eliminates this deviation.
· After installation or relocation, always check the zero point.
· If the instrument still detects a (steady) flow while all valves are closed and the fluid system is leak tight, adjusting the
zero point is recommended.
Prerequisites
Zeroing an instrument requires that:
· the ambient conditions (temperature, pressure) match those of the operating environment of the instrument
· the instrument is filled homogeneously and pressurized with the operational media, according to the typical process
conditions
· there is absolutely no flow through the instrument; preferably, this is achieved by closing a valve immediately after the
outlet of the instrument (control valve, shut-off valve)
Blocking the flow through the instrument is essential; zeroing an instrument while there is still a flow will lead to
measurement errors.
Procedure
FlowSuite provides a quick and easy way to adjust the zero point of an instrument; the Autozero function automatically
performs the procedure described here.
To adjust the zero point using digital communication, set parameter values in the following sequence (see section
Parameters for more information about instrument parameters):
Sequence #

Bronkhorst®
Instruction Manual FLEXI-FLOW™ Compact9.17.158A 17
The status indication light starts blinking blue (1 second on, 1 second off), indicating that the procedure is in progress.
On completion, the indication light assumes the color of the current instrument status .
If the procedure is successful, parameter Calibration Mode changes to 0 (idle). If the procedure fails, Calibration Mode changes
to 255.
After zeroing, parameter Control Mode returns to its initial value. The output signal should be 0 % (parameter Measure = 0).
After performing the procedure, remember to set parameter Init Reset to value 0 to lock secured parameters.
3.3 Maintenance
Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is
used in. Servicing must therefore be performed by trained and qualified personnel. Contact your Bronkhorst representative
for information about cleaning and calibration. Bronkhorst has trained staff available.
The FLEXI-FLOW™ needs no regular maintenance if operated properly, with clean, non-corrosive media, compatible with the
wetted materials, avoiding pressure and thermal shocks and vibrations.
· Before disconnecting or disassembling any fluid system related parts, always make sure the fluid system is depressurized.
· When depressurizing, prevent sudden pressure changes by shutting off the fluid supply gradually.
3.3.1 Cleaning
Fluid path
· The instrument's fluid path (the wetted parts) may be purged with a clean, dry and inert gas.
· In case of severe contamination, cleaning the wetted parts may be necessary. This requires the instrument to be returned
to the factory.
Exterior parts
The instrument's exterior can be cleaned with a soft, lint free cloth, preferably dry, or, if necessary, moistened with a mild
water soluble cleaning agent.
· Moisten the cloth only slightly, to prevent liquid from penetrating the instrument's interior and causing damage to the
electrical parts.
· Only use a water soluble cleaning agent, never an oil based liquid like paint thinner or white spirit, as these might
damage parts made of synthetic materials.
3.3.2 Calibration
The FLEXI-FLOW™ has been factory calibrated. Periodical inspection, recalibration or verification of the accuracy may be
subject to individual requirements of the user. Whenever necessary, contact your Bronkhorst representative for information
and/or making arrangements for recalibration.
Bronkhorst certifies that the instrument meets the rated accuracy. Calibration has been performed using measurement
standards traceable to the Dutch Metrology Institute (VSL).
3.4 Troubleshooting
General problems
· Electronic problems can be traced by restarting the equipment.
· If the equipment starts up normally, the measurement and control behavior can be checked by applying fluid pressure.
· To track down problems in the fluid system, depressurize the fluid system and disconnect the suspected unit from the
process line. Dirt or clogging might be quickly detected by visual inspection of disassembled fluid connections.
If you suspect leakage, do not disassemble the device for inspection, but contact your Bronkhorst representative for service
or repairs.
3.4.1 Zooming in on NAMUR status
Errors and warnings
Detailed error and warning information can be found by connecting the instrument to a Windows computer running
