OVERVIEW
Introduction
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 flowmeters and has a 4-20mA output for controlling a pump or valve.
Operational
There are two operation modes:
Hand: the control output can be manually changed, there is no loop connection.
Auto: the set point can be set and/or changed, corresponding with the process value of flow.
Display
The display has large 17mm segments which show flow rate, set point, alarms and total (resettable). On-screen engineering units are easily configured from a comprehensive selection.
Configuration
All configuration settings are accessed via a simple operator menu which can be passcode protected. Each setting is clearly indicated with an alphanumerical description, therefore avoiding 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.
Analog Output Signal
The flow rate is controlled via the (0)4-20mA or 0 - 10V DC output signal. The output signal is updated ten times per second. The output signal can be passive, active or isolated where the passive output type will loop power the F120 as well.
Signal Input
The F120 will accept most pulse input signals for 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.
Alarm Output
Two fixed alarm outputs are available to transmit the flow rate alarm condition, 1 low and 1 high alarm output. 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.
Safety Mode
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.
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).
Hazardous area
For hazardous area applications, this model has been ATEX certified Intrinsically Safe  II 1 GD EEx ia IIB / IIC T4 T100°C with an allowed operational temperature of -30°C to +70°C (-22°F to +158°F). A flame proof enclosure is also available with the rating II 2 GD EEx d IIB T5.
Enclosures
Various types of enclosures can be selected, all ATEX approved. As standard the F117 is supplied in a GRP panel mount enclosure, which can be converted to a GRP field mount enclosure. Most popular is our rugged aluminum field mount enclosure with IP67 / NEMA 4X rating. Both European or U.S. cable gland entry threads are available.

ORDERING INFORMATION
Standard Model Number Configuration: F120-P-AP-CX-EX-HC-IX-OT-PX-TX-XX-ZX
To aid in the construction of a Fluidwell model number a model configurator must be used. The path to this Configurator is contained in the link shown below. However, it would help to first review the options shown below.
NOTE: If you require the product to be Intrinsically Safe (ATEX, IECEx, CSA or c-us), the options you choose should only include those options that carry the ATEX symbol next to them. The Configurator will not allow you to mix and match options, unless the product is to be used in a Safe Area.
Once a new model is generated using the Configurator, you will
- see the price of the fully configured model
- have an opportunity to purchase the product
- have the capability to e-mail the configuration to us, yourself, or a third person
