FLOW RATE CONTROLLER
WITH ANALOG CONTROL OUTPUT
DATASHEET F120 - FLOW RATE CONTROLLER
AND HIGH / LOW ALARMS
Advantages
Signal output
• Robust IP67 (NEMA4X) field enclosure.
It is so rugged, you can even stand on it!
• Intrinsically Safe available - ATEX and IECEx
approval for gas and dust applications.
• Programming can be done by your own crew, with
the sensible menu-driven structure, saving cost
and irritation. Know one, know them all!
• Very diverse mounting possibilities: walls, pipes,
panels or directly onto outdoor sensors!
• (0)4 - 20mA / 0 - 10V DC control output e.g. to
control a valve.
• Two alarm outputs for low and high flow rate alarm
(not available with analog input).
Signal input
Flow
• Ability to process all types of flow meter signals:
Reed-switch, NAMUR, NPN/PNP pulse, Sine wave
(coil), Active pulse signals, (0)4 - 20mA, 0 - 10V DC.
Remote control
• Safety mode input.
• External reset / clear lock (optional).

Safety mode input to place the controller in a safe
predefined position.
Two alarm values can be entered in %: low and
high flow rate alarm.
Bumpless switching between 2 operation modes:
Hand and Auto.
Explosion/flame proof available.
Full Modbus communication RS232/485/TTL.
Loop or battery powered, 8 - 24V AC / DC or
115 - 230V AC power supply.
Applications
• The F-Series is your first and safest choice for field
mount indicators in safe and hazardous area
applications. Especially in harsh weather
conditions like rain, snow, salty atmosphers and
temperatures between -40°C up to +80°C
(-40°F up to 176°F).
• The F120 is designed flow rate control applications;
such as chemical processing, plastic manufacturing
and the aggregates and cement industry. For DIN
panel mount indicators, check our D-Series.

General information
Alarm output
Introduction
Two fixed alarm outputs are available to transmit the
The F120 is part of the Fluidwell process controller
family and is the alternative for local control loops.
The single loop flow controller accepts most pulse
inputs from flow meters and has a 4 - 20mA output
for controlling a pump or valve.
flow rate alarm condition, 1 low and 1 high alarm
Operational
Safety mode
There are two operation modes:
Hand: the control output can be manually
changed, there is no loop connection.
Auto: the setpoint can be set and/or changed,
corresponding with the process value of
flow.
The F120 has a safety mode that keeps on
transmitting a pre-defined value as long as the
contact is made. After releasing the contact, the
former value and function will be reinstalled.
output (not available with analog input). The output
signals can be a passive NPN, active PNP or an
isolated electro-mechanical relay. If there is a no-flow
the alarm output will be disabled.
Communication
All process data and settings can be read and
modified manually or through the Modbus
communication link (RS232 / RS485).
Full Modbus functionality remains available for the
Intrinsically Safe version (TTL).
Display
The display has large 17mm segments which show
flow rate, setpoint, alarms and total (resettable).
On-screen engineering units are easily configured
from a comprehensive menu.
Hazardous areas
Configuration
This model has been ATEX and IECEx certified
Intrinsically Safe for gas and dust applications,
with an allowed ambient temperature of
-40°C to +70°C (-40°F to +158°F). A flame proof
All configuration settings are accessed via a
simple operator menu which can be password
protected. Each setting is clearly indicated with an
alphanumerical description, which avoids
confusing abbreviations and baffling codes. Once
familiar with one F-series product, you will be able
to program all models in the series without a
manual. All settings are safely stored in EEPROM
memory in the event of sudden power loss.
Ex d enclosure with ATEX certification is also
available.
Enclosures
All enclosures are ATEX and IECEx approved. As
standard the F120 is supplied in an GRP panel
mount enclosure, which can be converted to an
IP67 / NEMA 4X GRP field mount enclosure by the
addition of a back case. Most popular is our rugged
aluminum field mount enclosure.
Analog output signal
The flow rate is controlled via the (0)4 - 20mA or
0 - 10V DC output signal. The output signal is
updated eight times per second. The output signal
can be passive, active or isolated where the
passive output type will loop power the F120 as
well.

output 1
Signal input
The F120 accepts most pulse and analog input
signals for volumetric flow or mass flow. The input
signal type can be selected by the user in the
configuration menu without having to adjust any
sensitive mechanical dip-switches or jumpers.
The analog input is available with lineair and
square root calculation and even as 4 - 20mA input
loop powered.
