F-Series - Fluidwell

General Information

Introduction

The F-Series product range offers you an extensive selection of indicators, controllers and monitoring systems for liquid and gas flow applications as well as for level, pressure and temperature measurement.

It’s sturdy industrial design is a major feature, utilizing an innovative die-cast aluminum case. Exceptional functionality has ensured that the F-Series has become a very popular range of local indicators, controllers and signal transmitters.

In addition to the extensive selection of models, a wide range of accessories and enclosures is available for the F-Series.

Industrial applications

The F-Series range has been developed for typical industrial environments. It is sturdy and weather-proof through it’s aluminum IP67 / NEMA 4X field enclosure. It can also be supplied in a more cost effective GRP enclosure with the same dimensions and ingress protection rating. The enclosure can be mounted directly onto sensors, walls or pipes but is also suitable for panel mount applications, with one major advantage: it requires minimal depth clearance. The operational temperature specification of the product ranges from -40° to +80° Celsius (-40°F to +178°F).

Operational

Fluidwell is acutely aware of the excessive amount of equipment which today’s technicians need to control. For this reason, a clear user-friendly menu structure was developed for programming all Fluidwell products a number of years ago: all models are programmed in the same logical manner. The configuration of the unit is completely menu-driven with understandable texts avoiding confusing abbreviations. There are no sensitive DIP-switches, you simply select "Sensor" as main function, after which you can select "NPN-input" or "Span".

The Operators main information is displayed in clear 17mm (0.7") and 8mm (0.3") alphanumeric characters. An adjustable bi-color backlight is available that will switch from green to red in case an alarm is triggered.

Input features

•

For flow-measurement, the instrument accepts signals from most flowmeters ranging from PD-meters with reed-switches or hall-effect sensors to turbine sine wave (coil) pick-ups and other NPN/PNP pulse outputs. NAMUR standard sensors and (0)4 – 20mA or 0 – 10V DC analog devices are also catered for.

•

For level, pressure and temperature measurement, inputs are available for (0)4 – 20mA or 0 – 10V DC signals. For temperature measurement, thermocouple and 2, 3 or 4 wire PT100 (PRTD) elements are also supported. Linearization of the input signal, square root calculation and data filter functions are all available.

Output features

Related to the functionality of the selected unit, the following output features are available:

•

Analog output proportional to the flow rate, level, differential, ratio, temperature, pressure or position. This turns the unit into a powerful transmitter with a local display. The (0)4 – 20mA or 0 – 10V DC analog output can also be used to control actuators.

•

Transistor or relay outputs for high and low alarms, pulse output, flow-direction as well as the control of valves / relays in batch control applications.

•

The RS232, RS485 or TTL interface makes it possible to communicate remotely, even with the battery-powered unit. All software parameters can be monitored / modified in addition to the usual transfer of data using the Modbus protocol.

Power management

During the development of the F-Series products, ultra-low power consumption was a key-requirement. Thanks to recent advancements in CMOS technology, Fluidwell has extended the battery life significantly and introduced several smart power-management functions. Result: a battery lifetime of seven years can be achieved. Additionally, several alternative means of powering the F-Series are available: loop-powered, 24V AC/DC and 115-230V AC.

Since all settings are stored in EEPROM memory, you won't lose information when replacing the battery or in the event of sudden power loss. A backup of the running totals is made every minute.

Hazardous area installation

The F0-Series have been certified according ATEX, IECEx, CSA c-us and FM for use in Intrinsically Safe applications with an ambient temperature of -40°C to +70°C (-40°F to +158°F).
