Level Indicators - Fluidwell

General Information

Introduction

The product group "Level Indicators" offers an extensive range of solutions from a basic level indicator up to a powerful level monitor with tank shape linearization, high / low level monitoring, signal transmission, four alarm outputs as well as full Modbus communication.

The functionality of these products are based on two main hardware platforms:

•

F0-Series platform: these products do offer one signal input only and can have one alarm output. This is our basic product range.

•

F1-Series platform: these products have one or more signal inputs, multiple outputs and communication option. This is our advanced product range.

Both platforms share the same technology, enclosures, display and options but are dedicated to their own typical functionality.

All models are available for both safe area and hazardous area applications. Moreover, wireless data transmission, remote level monitoring and vendor managed inventory - VMI - is offered with our M-series and ProcessMonitor.com products and services.

For an explanation of the various options such as analog and pulse output signals, communication, power supply and enclosures, please read the section detailing the F-Series products.

Operator information

The following features are available on all level indicator models. Further product specific features can be found in the products datasheet.

•

Clear operator information is a key feature of these products. Essential information is displayed as clear text (e.g. "Low level") and not as mysterious abbreviations.

•

The dedicated display shows two lines of information at the same time, so the actual level is displayed simultaneously with the height, percentage or alarm message.

•

The level is displayed with six 17mm (0.67") high digits with its engineering unit. The following units can be selected through software: ml, L, m³, GAL, USGAL, kg, lb, bbl or no unit.

•

The height or percentage filled is displayed with 8mm (0.31") digits. The following engineering units can be selected: mm, cm, m, mtr, inch, ft, mmwk, mmwc, cmwk, cmwc, mwk, mwc, inwc, ftwc, mBar, Bar, PSI or no unit.

Configuration menu

All configuration settings are accessed via a simple operator menu which can be passcode protected to prevent unauthorized access. Each setting is clearly indicated with an alphanumerical description, therefore avoiding confusing abbreviations and baffling codes. There are no sensitive DIP-switches or trimmers, you simply select "Sensor" as main function, after which you can select "span" or "offset" etc. 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. The clear and easy structured configuration menu is one of the most appreciated features of the F-Series.

Signal input type

For the level indicators, two basic signal input types are available:

•

Analog signal: (0)4 – 20mA or 4 – 20mA input loop powered version. The input signal can be tuned within this range (e.g. from 4.0mA to 10.0mA). To avoid signal processing at minimum signal, a low cut-off filter is available.

•

Analog signal: 0 – 10V DC. The input signal can be tuned within this range (e.g. from 2.0 to 5.0V DC). A low cut-off filter is available here too, to avoid signal processing at minimum signal.

Further, a digital filter can be set to a desired value to stabilize the level measurement reading. The offset function allows the sensor to be mounted above a not measured quantity (e.g. from 230 L). With the span, the indicator can be set to be operational within any desired range (e.g. from 230 L to 10,000 L).

Data protection

All settings are stored in EEPROM memory ensuring that information is not lost in the event of power failure or battery exchange. The configuration menu and alarm values can be passcode protected to prevent unauthorized access.
