SmartBox 2 - the remote level gauge with switching functions and mechanical level gauge type FSA-W
SmartBox 2 is an electronic remote level gauge with two potential-free relays and is suitable for non-pressurised tanks. The device fulfils the requirements of the German DWA-A 791 for a clear indication of the filling level as a volume with high accuracy.
Free capacity and filling
Using a free capacity display, tank truck drivers and operators can determine the maximum number of litres that will fit during the upcoming fuelling process. In this way, tank truck drivers and operators prevent the tank from being overfilled and the limit indicator from being activated.
Note:
The deliberate filling of the tank until the tripping of the limit indicator is not permitted!
Application example:
The mechanical level gauge type FSA-W determines the filling height according to the float principle in centimetres, which it then displays. Using an electronic interface, the measured value is relayed via a connection cable to the SmartBox 2 digital display unit, where it is converted into the set output value and shown on the display. A reserve tank is controlled by a potential-free relay contact.
