Versions of the VISY-X system
Two versions of the VISY-X system are available which differ in different data transmission
technology:
(1)
The wired version
(2)
The wireless version / radio system
2.1
Wired version
In most cases, data is transferred between the sensors and the VISY-Command central unit via
cable. This cable is also in charge of the voltage supply of the sensors. The wired version of the
VISY-X system is the standard version.
2.2
Wireless version / radio system
If no free cable ducts are available at the petrol station, it is possible to instead opt for the
wireless tank gauging system. In this case, the benefit of installing the wireless system is that it
does not entail any excavation work.
In the wireless system, the sensors are connected to a transmitter and powered by a battery.
The radio version of the central unit is equipped with a receiving module.
The radio system consists of the additional components:
•
VISY-RFR (radio frequency receiver, receiver installed in VISY-Command … RF)
•
VISY-RFT (radio frequency transmitter, transmitter with battery)
The installation procedure for the wireless system is described in the following technical
documentation:
VISY-RF III radio system, art. no. 350272
