1.1 Designated use
Tankvision is a dedicated tank inventory system which is operated via a standard web browser. It
does not require any proprietary software.
Tankvision is based on a distributed architecture on a Local Area Network (LAN). Due to its
modular structure it can be adjusted to any application. It is ideally suited for small tank farms with
only a couple of tanks, but also for large refineries with hundreds of tanks.
Tankvision consists of the following components:
• Tankvision NXA820 (Tank Scanner)
scans parameters from tank gauges and performs tank calculations
• Tankvision NXA821 (Data Concentrator)
summarizes data from various Tank Scanners NXA820
• Tankvision NXA822 (Host Link)
provides data to host systems (such as PLC or DCS) via Modbus
1.2 Installation, commissioning, operation
The Tankvision system is fail-safe and constructed to the state-of-the-art. It meets the appropriate
standards and EC directives. However, if you use it improperly or other than for its designated use,
it may pose application-specific hazards, e.g. product overflow due to incorrect installation or
configuration. Installation, electrical connection, start-up, operation and maintenance of the devices
must therefore be carried out exclusively by trained specialists authorised by the system operator.
Technical personnel must have read and understood these operating instructions and must adhere
to them. You may only undertake modifications or repair work to the device when it is expressly
permitted by the operating instructions.
