Fieldbus Protocols The Tank Side Monitor NRF590 supports all of the following industry standard communication protocols allowing it to be integrated with existing instrumentation and connect to host computer systems without the need for additional hardware. These protocols allow for piece-by-piece replacement and upgrading of older technologies to modern radar solutions. Sakura V1 V1 protocol provides a standard form of digital communication via a two-wire system.

Connection of the auxiliary energy The Tank Side Monitor can be AC or DC supplied, depending on the installed power supply board. The AC supply needs to be connected to the terminals marked L/+ (Line) and N/- (Neutral), corresponding with the phase/line and neutral wire. DC supply can be connected to the same terminals, for which it is necessary to connect the positive (+) to the terminal marked (L/+), and the negative to the terminal marked (N/-).

Operating concept The Tank Side Monitor is operated via a four-layer menu. The structure of the menu accounts for typical measuring tasks as well as for the individual instrument configuration and installation. In particular, the menu contains dynamic function groups which are only indicated if the respective option is installed or the respective instrument is connected. This structure ensures clarity and simple operation without restricting the scope of functionality.
