OVERVIEW
Introduction
The F112 provide very precise linearization of the flowmeters signal. In addition to the average K-Factor or Span, fifteen linearization points can be entered with their frequencies or values. The unit will interpolate between these points greatly enhancing accuracy in any flow range. This linearization affects all displayed information as well as the signal outputs. A wide selection of options further enhance this models capabilities, including Intrinsic Safety and full Modbus communication.
Display
The display has large 17mm (0.67") and 8mm (0.31") digits which can be set to show flow rate and totals. On-screen engineering units are easily configured from a comprehensive selection. The linearized accumulated total can register up to 11 digits and is backed-up in EEPROM memory every minute.
Configuration
All configuration settings are accessed via a simple operator menu which can be pass-code protected. Each setting is clearly indicated with an alphanumerical description, therefore avoiding confusing abbreviations. 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 failure.
Analog Output Signal
The linearized flow rate is re-transmitted with the (0)4-20mA or 0 - 10V DC output signal. The output signal is updated ten times per second with a filter function being available to smoothen out the signal if desired. The output value is user defined in relation to the flow rate, e.g. 4mA equals to 15L/Hr and 20mA equals to 2000L/Hr. The output signal can be passive, active or isolated where the passive output type will loop power the F112 as well.
Pulse Output
The scalable pulse output, reflects the count on the accumulated display. The pulse length is user defined from 0.008 second up to 2 seconds. The maximum output frequency is 64Hz. The output signal can be a passive NPN, active PNP or an isolated electro-mechanical relay.
Signal Input
The F112 will accept most pulse and analog input signals for flow or mass flow measurement. The input signal type can be selected by the user in the configuration menu without having to adjust any sensitive mechanical dip-switches.
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 F112 is supplied in a 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 with IP67 / NEMA 4X rating. Both European or U.S. cable gland entry threads are available.

ORDERING INFORMATION
Standard Model Number Configuration: F112-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 c-us or FM.), 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
