2.3 Designated use
2.3.1 Application
The Tankvision Gauge Link is a tank gauging protocol converter to allow integration of third
party gauging equipment into the Tankvision system. The Tankvision Gauge Link is available
with a range of different field bus interface options. Most field bus interfaces will support
connection of a number of gauges in a “multi-drop” or bus configuration. The number of
gauges which may be configured in the Tankvision Gauge Link is limited to 32, which should
be adequate for most typical tank gauging field busses, however electrical and / or protocol
limitations may reduce this number. The functionality which obtains will be determined by
that offered by the connected gauge(s) and the interface / protocol.
Connection to the host system is via EIA/TIA-485 (formerly RS-485) Modbus. This is
primarily intended for “one-to-one” connection with the Tankvision Tank Scanner or similar
device.
The Tankvision Gauge Link must only be used in “safe” areas where there is no hazard from
the presence of potentially explosive or flammable atmospheres.
The Tankvision Gauge Link has not been assessed in respect of functional safety.
Accordingly it is not intended to be used as a safety critical component or part of a safety
critical system or in the implementation of any safety function.
