Level indicators

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 this product group is based on two product series:

  • F-Series: this product range is supplied in a robust IP67 (NEMA Type4X) field mount enclosure and suitable for safe and hazardous area applications. The F-Series have been certified according ATEX and IECEx by DEKRA and according CSA C-US and FM for use in Intrinsically Safe applications. The F-Series is resistant to harsh weather conditions (rain, snow, salty atmospheres, temperatures between -40°C/-40°F and +80°C/+178°F) without use of expensive protective cabinets.
  • D-Series: these products are supplied in a unique DIN panel mount enclosure and is only suitable for safe area applications. The robust IP66, IP67 (NEMA Type4X) front enclosure is made of die cast aluminum and is unequaled by any panel mounted indicator in the market: The D-Series is able to withstand total immersion and even powerful water jets!

Wireless data re-transmission and remote level monitoring is offered with the ProcessMonitor products and services .

Easy menu structure

The F-Series and D-Series are outstanding user-friendly. No configuration with complicated hardware changes or actions! Instead, each product offers the same simple, logical menu-driven structure. Each setting is clearly indicated with an alphanumerical description, without confusing abbreviations and difficult codes. Once familiar with a Fluidwell product, you can program ALL models in ALL series without need for a manual: Know one, know them all!

Both series have so many different combination possibilities for sensor in- and outputs, power and sensor supplies, communication and external inputs, that Fluidwell is able to produce no less than 200,000 different versions! With this variety of combinations, there is always a D- or F-Series that meets your technical requirements. For an explanation of the various options, please read the section detailing the F-Series or the D-Series products.

Operator information More >>

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.

Signal input type More >>

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 for only a few models. 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 More >>

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 password protected to prevent unauthorized access.
