SmartBox AIR Wi-Fi

is a battery-operated, electronic remote level gauge for a non-pressurised tank with a liquid operating medium


consisting of: digital display unit with a 16-digit LC display, pressure pump and compatible measuring hose with weighted sleeve

Operating media:
waste oil, diesel, FAME, fuel oil, fuel oil bio, HVO, vegetable oil, rainwater and other water-endangering, non-flammable liquids

Function:
The tank volume is determined by measuring the filling height on the basis of the pneumatic measuring principle. For this purpose, the measuring hose is inserted into the tank up to the tank bottom and filled with the operating medium according to the filling level. The hose is inserted into the tank either by being connected to an existing measuring line in the tank or by using the enclosed assembly kit in an available tank opening.

The pressure pump is activated and pumps the medium out of the hose either by a manually triggered measuring process or by cyclic automatic measurements (hourly, daily, weekly, monthly). The time required for the pressure pump to pump all the medium out of the hose corresponds to the current filling level in the tank.

After each measuring process, the tank volume is then shown on the display together with the free capacity display. The free capacity display represents the filling volume that fits into the tank during the impending filling process.

The tank volume is displayed in litres, volume percent or filling height in centimetres, depending on the individual settings. These settings, along with all the other settings, can be conveniently defined and changed via a website on a smartphone by scanning a QR code on the device.

After a single login of the device onto the local WiFi network, information such as the filling level and battery status can be retrieved using the mobile phone app updated to the hour, day, week or month, depending on individual settings. This is possible if the mobile phone is connected to any network anywhere in the world.
