NEW: F490 Loop Powered - Multi Purpose Indicator

Robust and user-friendly

The F490 is a versatile, loop powered Multi Purpose Indicator which displays the actual process value, range and loop current. Besides the focus on level, temperature and pressure applications, the F490 can also work with other measuring units, such as %, mA, RPM and more. Therefore, the F490 is a versatile indicator that suits many applications.

At the F490, the input circuit is separated from the backlight circuit. It is designed in such way that it does not influence the intrinsically safe circuit to which it is connected.

The F490 accepts 4 - 20mA input signals from a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters. All these process parameters can be displayed in their own engineering units. Thanks to its ruggedness, the F490 withstands extreme weather conditions such as rain, snow, sun, sandy deserts, salty atmospheres and temperatures between -40°C/-40°F and +80°C/+178°F without the need for expensive protective cabinets. Moreover, all products in the F-series are robust by design: even a truck can stand on them.

Mounting made easy

The F490 has extensive mounting possibilities. Simply attach it to panels, to walls or on pipes. In fact, mounting, installing and programming the F-series is unparalleled easy and user-friendly. Your commissioning crews can swiftly execute the installation themselves, saving you the cost, time and hassle of hiring external specialists.


The configuration of the F490 is done via a simple, logical and menu-driven structure (instead of complex hardware changes or actions). The alphanumerical descriptions enhance the easy understanding of the system and its settings, in contrast with regularly seen confusing abbreviations and complex codes. The F490 is, like all products in the F-Series designed according the ‘Know one, know them all’ – principle. Once familiar with an F-Series product, users can program ALL models in ALL series without the need for a manual. This way, Fluidwell allows users to save on programming time and costs, during installation and with each modification of settings.
