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.

1.3 Notes on safety conventions and symbols
In order to highlight safety-relevant or alternative operating procedures in the manual, the following
conventions have been used, each indicated by a corresponding symbol in the margin.
Safety conventions
#Warning!
A warning highlights actions or procedures which, if not performed correctly, will lead to personal
injury, a safety hazard or destruction of the instrument
"Caution!
Caution highlights actions or procedures which, if not performed correctly, may lead to personal
injury or incorrect functioning of the instrument
!Note!
A note highlights actions or procedures which, if not performed correctly, may indirectly affect
operation or may lead to an instrument response which is not planned
Explosion protection
0Device certified for use in explosion hazardous area
If the device has this symbol embossed on its name plate it can be installed in an explosion hazardous
area
-Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous areas. Devices located in and wiring
entering areas with the designation “explosion hazardous areas” must conform with the stated type
of protection.
.Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas. Devices located in
safe areas still require a certificate if their outputs run into explosion hazardous areas
Electrical symbols

A terminal to which or from which a direct current or voltage may be applied or supplied
&Alternating voltage
A terminal to which or from which an alternating (sine-wave) current or voltage may be applied or
supplied
)Grounded terminal
A grounded terminal, which as far as the operator is concerned, is already grounded by means of an
earth grounding system
*Protective grounding (earth) terminal
A terminal which must be connected to earth ground prior to making any other connection to the
equipment
