OVERVIEW

Introduction

The flow computer Model F114 has been developed to calculate the actual ratio between two separate flows. Typical applications are found where locally a two component product is mixed, for example in construction works, roof or wall isolation, glueing and coating. The F114 offers the facility to set two low ratio and two high ratio alarm values. Special precautions are taken to allow start-up problems and incorrect ratio readings for a certain period of time. Based on the location of the flowmeters, a selection can be made out of six different formulas. A wide selection of options further enhance this models capabilities.

Display

The display has large 17mm (0.67”) and 8mm (0.31”) digits which show the ratio, alarm values, flow rate A, total A and flow rate B, total B. On-screen engineering units are easily configured from a comprehensive selection. The ratio can be displayed as 1:__ or as a percentage.

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 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 failure.

Analog Output Signal

The calculated ratio, flow rate A or B can be re-transmitted with the (0)4 - 20mA or 0 - 10V DC output signal. The output signal is updated ten times per second. The output value is user defined in relation to the ratio or flow rate, e.g. 4mA equals to 1 : 50 and 20mA equals to 1 : 1. The output signal can be passive, active or isolated where the passive output type will loop power the F114.

Alarm output

Up to three outputs are available to transmit the ratio alarm condition. All free configurable, in such a way that you can have e.g. one low-low alarm output, one low alarm output and one high alarm output. The output signals can be a passive NPN, active PNP or an isolated electro-mechanical relay. Two outputs are available in Intrinsically Safe applications.

Signal Input

The F114 will accept most pulse and analog input signals for flow or mass flow measurement. The input signal types can be selected by the user in the configuration menu without having to adjust any sensitive mechanical dip-switches or jumpers.

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 F114 is supplied in an GRP panel mount enclosure, which can be converted to an 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.

HAZARDOUS AREA APPLICATIONS

The F114-XI has been ATEX approved by KEMA for use in Intrinsically Safe applications. It is approved according to

II 1 GD EEx ia IIB/IIC T4 T100°C for gas and dust applications with an operational temperature range of -30°C to +70°C (-22°F to +158°F). Besides the two I.S. power supplies for the alarm outputs, it is allowed to connect up to four I.S. power supplies in IIB applications or one in IIC applications. Full functionality of the F114 remains available, including 4 - 20mA output, alarm outputs and Modbus communication (type CT).

Standard Model Number Configuration: F114-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
