THE Micropilot-M radar level measuring device from Endress+Hauser is now available in two new versions specifically for the chemically aggressive, pharmaceutical and food industries.

Although the instrumentation requirements of these two industries are very different; material compatibility with the process, size of antenna, and susceptibility to condensation in the vessels are a combination of factors common to these industries, which often create problems for users selecting microwave (radar) technology as a level measurement principle.

Both new models have complete Teflon-encapsulated horn antennas. The Micropilot FMR244 stub-antenna comes with threaded and food process connections for tanks with small process connections, whilst the FMR245 flush-mounted antenna with flanged and food connection offers solutions for taller tanks.

Both models offer excellent chemical resistance with no metal wetted parts and the Teflon encapsulation has FDA (Food & Drug Administration) approval, which together with plastic and glass epoxy substrate make them almost impenetrable to chemical diffusion.

This design results in a reliable, accurate, continuous level measurement in all difficult hygienic application.

Added to the analog 4-20mA output, are digital communications in HART, Profibus-PA and Foundation Fieldbus. All these protocols are available for EEx ia or EEx d operation.

The new models of the Micropilot-M family also offer signal analysis as an envelope curve on the instrument display, thus permanently providing information about the reliability of the measurement.

The four line 80-character display permits simple menu-driven operation. The user-friendly operating software, ToF-Tool (time of flight), for remote PC configuration is supplied free of charge and permits simple handling of measuring points, uncomplicated commissioning, optimising, diagnostics and measuring point documentation.

The new versions of Micropilot extend the range of applications suitable for radar level measuring technologies, especially in hygienic environments.
