2.3 Designated use
2.3.1 Application
Tankvision is a dedicated tank inventory management system.
Components:
• Tankvision Tank Scanner NXA820
scans parameters from tank gauges and performs tank calculations
• Tankvision Data Concentrator NXA821
summarizes data from various Tank Scanners NXA820
• Tankvision Host Link NXA822
provides data to host systems (such as PLC or DCS) via Modbus
The above mentioned components are 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 Application
Endress+Hauser 7
3Application
3.1 Inventory control
By using Tankvision to monitor the tank level and stored volume of valuable liquids
remotely, owners or operators of tank farms or terminals for petroleum products and
chemicals (liquids) can visualize the volumes or mass of the stored medium in real time. The
data can be used to plan the inventory and distribution. The data can also be used to manage
tank farm operations like pumping or transferring products.
Tankvision has its unique concept using network technology. Without using proprietary
software, the users can visualize and manage their valuable liquids stored in the tanks by a
web browser.
Tankvision is a flexible and cost effective solution due to its scalable architecture. The
application coverage goes from small depots with only a few tanks up to refineries.
3.2 Application areas
• Tank farms in refineries
• Ship loading terminals
• Marketing and distribution terminals
• Pipeline terminals
• Logistic terminals for tanks storing products like crude oils, refined white and black
products, chemicals, LPGs, fuels, biofuels, alcohols

4.2 Tank Scanner NXA820
• The Tank Scanner NXA820 connects multiple tank gauges:
from up to 15 tanks via one field-loop. The Tank Scanner NXA820 supports different field
protocols (Modbus EIA485, Sakura V1, Whessoe WM550).
• The measured values are transmitted by the network and visualized on HTML pages.
• The Tank Scanner NXA820 can be used stand-alone for small tank farms, but also be
integrated into a large system for use in refineries.
• The Tank Scanner NXA820 is equipped with a full set of tank inventory calculations. The
calculations are based on various international standards such as API, ASTM, IP and many
others. Measured values are used to calculate volume and mass.

4.3 Data Concentrator NXA821
• The NXA821 Tankvision Data Concentrator is the enhanced solution for large tank farms
and refineries. The Data Concentrator is required if:
The plant contains more than one field loop (each of which has its own Tank Scanner
NXA820) and tanks of more than one Tank Scanner NXA820 are to be grouped
• The Data Concentrator collects the data of several Tank Scanner units and enables
reconciliation and totalization of the tank data of many or all tanks in structured groups.
• Alarms and events from all connected Tank Scanners NXA820 can be shown in a common
screen. Any tank of the system can be assigned to any tank group, regardless of the Tank
Scanner it is linked to. This ensures the highest possible flexibility for the plant or tank
farm.
• An alarm pop-up shows alarms of all connected Tank Scanners NXA820 even if the web
browser is closed.
• Direct serial printer connection for report printing (W+M certified acc. PTB)
• 90 tanks (more on request) can be allocated to each Data Concentrator NXA821. Each of
these tanks must have been allocated to a Tank Scanner NXA820 beforehand.
• Tanks from up to 6 different Tank Scanners NXA820 (more on request) can be integrated
in this way.
