Instruction Manual ES-FLOW™9.17.145E 7
1Introduction
1.1 Scope of this manual
This manual covers general product information, installation and operating instructions and troubleshooting tips for the
ES-FLOW™ digital volume flow meter/controller for liquids.
1.2 Intended use
The ES-FLOW™ has been designed to accurately measure and control low volume flows with high precision and a limited
pressure drop. A wide range of liquids can be measured independent of fluid density, temperature and viscosity.
When ordered as a 3-A compliant instrument, the ES-FLOW™ is suited for hygienic (food processing) applications, Clean-in-
place (CIP) and Sterilization in Place (SIP). The end user is responsible for the selection and application of suitable (FDA-
compliant) sealing materials.
The wetted materials incorporated in the ES-FLOW are compatible with media and conditions (e.g. pressure, temperature)
as specified at ordering time. If you are planning to use the product (including any third party components supplied by
Bronkhorst, such as pumps or valves) with other media and/or other conditions, always check the wetted materials
(including seals) for compatibility. See the technical specifications of the product and consult third party documentation (if
applicable) to check the incorporated materials.
Responsibility for the use of the equipment with regard to suitability, intended use, cleaning and corrosion resistance of the
applied materials against the processed media lies solely with the end user.
Where appropriate, this document recommends or prescribes safety measures to be taken with respect to media usage or
working with the described equipment under the specified conditions. The end user is responsible for taking the necessary
safety precautions and proper use of appropriate (personal) protective equipment, even if such is not explicitly
recommended or required in this document.
The end user is considered to be familiar with the necessary safety precautions, and to comply with the appropriate
protective measures as described in the Material Safety Data Sheets of the media to be used in the system (if applicable).
Bronkhorst High-Tech B.V. cannot be held liable for any damage resulting from improper or unsafe use, use for other than
the intended purpose or use with other media and/or under other conditions than specified on the purchase order.
1.3 Product description
The ES-FLOW™ is a precise and compact volume flow meter with control function for liquids, based on a novel ultrasonic
technology.
Measuring principle
Measuring is done in a straight tube, without obstructions or dead spaces. Multiple transducers measure both the surface
acoustic wave and the transit time through the media. All up- and down-stream combinations are recorded and processed
in nanoseconds. The sound wave velocity and the surface area are recalculated to the volume flow value. This ultrasonic
measuring method is fast, accurate and inherently bi-directional.

Bronkhorst®
Instruction Manual ES-FLOW™ 9.17.145E8
Application
The combination of a straight sensor tube with zero dead volume, self-drainability and hygienic connections, makes the ES-
FLOW especially suitable for hygienic applications. Examples of typical use are the measuring of food ingredients like
flavourings or syrups, or measuring concentrates in CIP units. For non-hygienic applications, the instrument can be
equipped with compression type fittings. Wetted parts are made of stainless steel, the housing has a high ingress
protection rating.
Operation
The ES-FLOW™ can be operated with the integrated readout and control unit, as well as digitally, via RS-232 or fieldbus
(Modbus, FLOW-BUS, PROFIBUS DP, PROFINET, DeviceNet™ or CANopen®), or in analog mode. The readout and control unit
has a capacitive touchscreen with a TFT display. The fluid temperature can be read out as a secondary output. An on-board
PID controller can be used to drive a control valve or pump, establishing a complete, compact control loop.
By default, the instrument is supplied with the readout and control unit above the measuring tube (assuming the flow
direction is to the right). If so required, the flow direction and display orientation can be customized to support a
convenient reading angle. The illustrations in this manual are based on the default orientation.
Multi-range
The ES-FLOW™ offers multi-range functionality: factory calibrated ranges can be re-ranged to a different full scale range.
Because of the extremely high linearity of the sensor, this does not affect the original accuracy specifications.
The instrument comes with a calibration certificate for all supported full scale ranges. The actual full scale of the instrument
is set to a value as ordered.

1.5.1 Customized I/O options
ES-FLOW™ instruments offer various customized input/output functions through pin 5 of the M12 connector and through
pin 2 of the M8 connector as an option. I/O options are factory installed as specified at ordering time, and cannot be
changed manually.
The last 3 groups of the model key on the serial number label indicate the installed I/O configuration. The possible
configurations are described in the table below. See the hook-up diagram for custom bus and I/O configurations
(document 9.16.196) for an explanation of the codes.
Code
Description
000
Disabled, pin 5 is pulled down to 0 Vdc (default selection)
A1V*
0…10 Vdc sourcing output, controller
Analog signal for pump or external valve steering (control signal only)
When the controller output is used for pump or external valve steering (mass flow meters only), make sure
to set parameter Valve maximum to 0.3 [A]. For mass flow controllers, the controller output is limited to a
value below 10Vdc, due to the maximum valve current restriction.
B1V*
4…20 mA sourcing output, controller
Analog signal for pump or external valve steering (control signal only).
When the controller output is used for pump or external valve steering (mass flow meters only), make sure
to set parameter Valve maximum to 0.3 [A]. For mass flow controllers, the controller output is limited to a
value below 20 mA, due to the maximum valve current restriction.
B2V*
3.8…20.8 mA sourcing output, controller
Analog signal for Badger Meter valve with TEIP11 signal converter (control signal only)
C3A
Digital output, min/max alarm
During a min/max alarm, pin 5 is pulled down to 0 Vdc.
C4A
Digital output, counter alarm
During a counter alarm, pin 5 is pulled down to 0 Vdc.
C5S
Digital output, enabled by setpoint (for shut-off control)
Pin 5 is pulled down to 0 Vdc at a controller setpoint, e.g. for shut-off valve activation.
For factory selected analog control (…-A#-C5S):
If parameter Control mode is set for analog control by factory, the minimum setpoint at which the device
(shut-off valve) connected to pin 5 is activated is 1.9%. This prevents possible noise on the analog input
activating the device accidentally.
For factory selected digital control (…-D#-C5S):
If parameter Control mode is set for digital control by factory, the setpoint threshold for activating the
device connected to pin 5 is any value > 0.
Note: If the instrument is forced into Valve Safe State, the digital output is not affected, so a (n.c.) shut-off
valve connected to pin 5 will not close when the (n.c.) controller is in Valve Safe State’
Make sure to use 24 Vdc power supply corresponding to the shut-off valve specifications.
C0I
Digital output, high/low switch via remote parameter (e.g. for shut-off valve control)
Pin 5 is pulled down to 0 Vdc when writing value 1 to parameter IO switch status, this is undone by writing
value 0.
A device connected to pin5 (e.g. a shut-off valve) can be activated/deactivated by writing parameter IO
switch status.
Note: If the instrument is forced into Valve Safe State, the digital output is also affected, so a (n.c.) shut-off
valve connected to pin 5 will be closed when the (n.c.) controller is in ‘Valve Safe State’.
Make sure to use 24 Vdc power supply corresponding to the shut-off valve specifications.

Code
Description
D9E
Digital frequency output, measure
Measurement value is translated to a frequency within given frequency range.
The default frequency range to represent 0…100% flow is 0…10000 Hz. Any other frequency range must be
specified on order.
F9B
Digital pulse output, batch counter
Pin 5 is pulled down to 0Vdc when a given batch size is reached (during a given pulse length).
By default, a pulse is given at each 1x the Counter unit batch value, with a pulse length of 1 second. For
instance, when Counter unit is set to 'ln', a pulse is given each time 1 ln has passed through the instrument.
An alternative pulse length must be specified on order.
Provide a pull-up resistor of 5…10 kOhm to create 15…24 Vdc at pin 5 (according to the applicable hook-up
diagram).
I3C
Digital input, controller mode valve close
Valve closes when pin 5 is connected to 0 Vdc.
This option switches between the default Control mode and mode ‘Valve Close’ (value 3). When the default
Control mode is digital, the default value is 0 (bus/RS-232), when the default Control mode is analog, the
default value is 1 (Analog input).
I8C
Digital input, controller mode valve purge
Valve is fully opened when pin 5 is connected to 0 Vdc.
This option switches between the default Control mode and mode ‘Valve Fully Open’ (value 8). When the
default Control mode is digital, the default value is 0 (bus/RS-232), when the default Control mode is analog,
the default value is 1 (Analog input).
I1R
Digital input, reset counter
The counter resets when pin 5 is connected to 0 Vdc.
I2R
Digital input, reset alarm
The alarm resets when pin 5 is connected to 0 Vdc.
*) Notes regarding controller options:
·A controller output option (A1V, B1V or B2V) can only be installed in combination with controller mode A or D
(controller enabled, see model key).
·If the controller is enabled, the M8 connector can always be used to control a Bronkhorst® valve (through pin 3).
·Although it is theoretically possible to have 3 controller options installed, no more than 1 signal should be used at any
time.

2Installation
This chapter describes the steps to take in order to prepare the ES-FLOW™ for first time use.
2.1 Functional properties
Before installing the ES-FLOW™, check if the functional properties match your requirements. The
ES-FLOW Brochure provides general technical specifications, specific technical data can be found
on the serial number label and in the purchase oder.
·Flow/pressure rate(s)
·Media to be used in the instrument
·Upstream and downstream pressure(s)
·Ambient temperature
·Input and output signal
Bronkhorst® instruments are pressure tested to 1.5 times the requested pressure rating and outboard leak tested to at least
2 * 10-9 mbar l/s Helium. The tested pressure is specified on the serial number label. If the serial number label is missing or if
the specified pressure is insufficient, the instrument must not be used and should be returned to the factory.
Before installation, make sure that the tested pressure is in accordance with the safety factor of your application. The tested
pressure must always be higher than the maximum operating pressure.
2.2 Mounting
2.2.1 Location
Gas bubbles in the liquid can lead to measurement errors. In general, the
instrument should be mounted in a pipe segment where gas bubbles
cannot accumulate. The image to the right shows the preferable
mounting locations.
For hygienic applications some additional recommendations apply (see
further).
·In general, the best location is a horizontal pipe segment or a segment where the fluid direction is upward.
·Gas might accumulate in the horizontal segment if it is followed by a downward segment. Do not mount
the instrument in a location like this.
·Mounting in a downward pipe segment with an open end is strongly dissuaded, especially if the pipe
diameter is 1/2" or more. Gravity might let the segment run empty; depending on the specific system
dimensions and the viscosity of the metered fluid, this effect might be stronger or weaker.
·If the instrument is part of a closed fluid system, mounting the instrument in a downward pipe segment is
not preferable, but may be considered if other mounting locations are problematic.
To minimize the risk of gas inclusion by cavitation, the preferred location to install a control valve is downstream from the
instrument, the preferred location for a pump is upstream.
To prevent damage to the internal electronics, make sure the temperature inside the instrument housing does not get
above 60 °C. If necessary, take appropriate heat dissipation measures, especially if the instrument is operated inside an
enclosure (e.g. a control cabinet).

Bronkhorst®
Instruction Manual ES-FLOW™9.17.145E 13
2.2.2 Orientation
·In hygienic applications, the ES-FLOW™ should be mounted in such a way that it allows self-draining (see further).
·To prevent liquid from pooling on the display surface, the instrument should not be mounted with the display surface
facing up.
·Other than that, the instrument has no preferred mounting orientation.
Note that the connection between the measuring tube and the electronics housing is fixed; the housing
cannot be rotated to get a better view of the display. Its orientation can only be altered by
repositioning the entire instrument.
On models starting from MkII, the flow direction and display orientation can be adjusted at the
factory, for which the instrument has to be returned. Contact your Bronkhorst representative for more
information and arrangements.
2.2.3 Hygienic applications
In order to comply with the 3-A Sanitary Standards, the ES-FLOW™ should be mounted in a location where its exterior
cannot come into direct contact with food substances and/or the product contact surfaces of their packaging material.
For Sterilization in Place (SIP) it is advised to mount the instrument with the electronics housing (display) below the sensor
tube, to prevent rising hot air from damaging the display and/or electronics.
To allow self-draining, mount the ES-FLOW™ vertically or with a minimum inclination of 10°, with the normal flow going
upward (note the FLOW arrow on the instrument).
2.3 Fluid connections
The FLOW arrow on the measuring tube indicates the normal flow direction. For normal use, install the ES-FLOW™ in the
process line, in accordance with the direction of the FLOW arrow. For bi-directional measuring, install the instrument in the
direction in which the highest flow will be measured (if applicable). When deciding which direction to install the instrument
in, take into account that the measuring range in the reverse direction is approximately 73% of the full scale range (whereas
the instrument can measure 131% FS in the normal direction).
Tighten fittings according to the instructions of their manufacturer.
·Use piping or tubing that is suitable for the operating conditions of the application (media, maximum temperature,
maximum operating pressure).
·Do not install small diameter piping/tubing on high flow rates and avoid abrupt angles or other disturbances within a
distance of 10 times the (inside) pipe diameter from the inlet or outlet of the device.
·Do not install pressure regulators within a distance of 25 times the (inside) pipe diameter from a controlling instrument.
Check the fluid system for leaks before applying full operating pressure, especially when using hazardous media (e.g. toxic
or flammable).

Bronkhorst®
Instruction Manual ES-FLOW™ 9.17.145E14
2.4 Electrical connections
The ES-FLOW™ is equipped with one or more electrical connection ports. The image to the
right shows the locations of the different ports (the actual presence and appearance of ports
might be different, depending on the ordered fieldbus interface and instrument type):
1. Standard connection port, 8-pin M12 male
2. Fieldbus connection port, 5-pin M12 male/female (optional, fieldbus dependent)
3. Connection port for actuator output, 4-pin M8 female
4. 2nd fieldbus connection port, 5-pin M12 male/female (optional, fieldbus dependent)
See sections Model key and Functional properties for configurable and installed options
respectively.
Upon delivery, all connection ports are capped. To maintain the original ingress protection rating, do not remove the caps
of unused connectors.
·Electrical connections must be made with standard cables or according to the applicable hook-up diagram.
·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 is suitable for the power ratings as indicated on the serial number label (see model key)
or in the technical specifications, and that double or reinforced insulation is used for the power supply.
·Before powering up, make sure all required cabling is properly connected.
·Before each use, inspect cabling and connectors for damage.
Never power the instrument simultaneously from two different power sources (e.g. fieldbus and Plug-in Power Supply).
Doing so will damage the printed circuit board irreparably.
The device described in this document contains electronic components that are susceptible to electrostatic discharge. In
order to prevent damage, proper handling procedures must be followed during installation, (dis)connecting and removing
the electronics.
The device carries the CE-mark and is compliant with the concerning EMC requirements. However, EMC requirements
can only be met using appropriate cables and connector/gland assemblies. Bronkhorst recommends the use of their
standard cables. These cables have the right connectors and loose ends (if any) are marked to help prevent wrong
connection. When using other cables, cable wire diameters must be sufficient to carry the supply current, and voltage loss
must be kept as low as possible. When in doubt, contact your Bronkhorst representative.
When connecting the product to other devices, be sure that the integrity of the shielding is not affected; always use
shielded cabling for signals and communication and do not use unshielded wire terminals.
2.5 Communication interface
Check if the default network settings match the configuration of the fieldbus system (if applicable). If necessary, the default
settings can be overruled by changing the appropriate parameters (see Network configuration).

3Operation
3.1 Powering up and powering down
It is recommended to turn on power before applying fluid pressure and to switch off power only after relieving fluid pressure.
When applying pressure, avoid pressure shocks and bring the fluid system gradually up to the level of the specified
operating conditions; open the fluid supply gently.
3.2 First use
Bronkhorst does the utmost to ensure that you receive a clean product.This does not, however, relieve the end user of the
responsibility to ensure that the instrument and the system in which it is incorporated meet (hygiene) requirements that
apply to the intended use of the instrument. The responsibility for cleaning the equipment to meet such requirements lies
exclusively with the end user.
Before starting measurement and control, make sure to remove gas from the fluid system by flushing all fluid lines with the
process fluid at a relatively high flow rate.
For instruments with a control function, the highest possible flow rate is ensured by giving setpoint = 100% or using special
Control mode = 8 (valve fully open). Control mode 8 bypasses the PID controller, which is particularly useful when having
the ES-FLOW™ set to a low capacity flow range.
