SmartBox 4 NB-IoT

is an electronic remote level gauge for a non-pressurised tank with a liquid operating medium including data transmitter


The integrated modem transmits tank information, such as filling levels and critical conditions (minimum filling level, system malfunction, e.g. burner malfunction, leakage notification, etc.), via the NB-IoT radio standard.

Function:
The tank content is determined by the selected probe and relayed to the display unit by means of a 4-20 mA signal. After entering the tank data in the display unit upon start-up, the conversion of the measured values is carried out automatically and is displayed on the display unit.

The right solution for:

  • the monitoring of tank and consumer units
  • the remote transmission of tank contents and data

The data is communicated:

  • to the Internet database www.smart-inspector.com for the full monitoring of the system. If configured appropriately, this resource can carry out measures independently, such as ordering fuel or deploying technicians.

Required for operation:
An NB-IoT data card is included. The invoicing of user fees of the Smart-Inspector Internet database (www.smart-inspector.com) for the system hosting, administration, backup and processing of tank data is carried out by a third-party provider. A registration form is enclosed with the appropriate products.

  • display unit with 2-line LC display
  • the measured data is shown on the digital display unit optionally as litres, percentage by volume or as the filling height in centimetres
  • display of the maximum permitted discharge volume (free capacity display)
  • menu language and display in German, English, French or Spanish

  • supply voltage: 230 V AC 50 Hz
  • type of protection: IP54
  • interface: optionally upgradeable for 4–20 mA, 0–5 V, M-Bus, H-protocol, for example
  • event notification input, e.g. for reporting a system malfunction
  • 1 relay with normally closed and normally open contact maximum 250 V AC - maximum 3.5 A

  • For more components, refer to accessories and add-ons.

Special solutions for EX protection zones or temperature measurement, or other tank heights, media or service tanks available on request.

When selecting the level probe, the tank height and density value of the operating medium must be taken into account. This is the only way to select the correct measuring range. Please also ensure that the level probe is suitable for the medium in use.
