Page 1/15 Overview1 OverviewThe VISY-Density (LPG) module is an extension of the VISY-Stick Advanced level sensor inthe VISY-X system for the measurement of product/sump density of fuel or liquefiedpetroleum gas (LPG). The module is available for use in fuel tanks as "VISY-Density" andfor use in LPG tanks as "VISY-Density LPG".The VISY-X system (Volume Information System) provides highly precise and continuousfilling level measurements for all commercially available fuels and liquefied petroleum gasin up to 16 tanks. The product temperature and the water level are gauged simultaneously.The VISY-X system comprises:• VISY-Command (evaluation unit)• VISY-Setup (software for configuring the VISY-Command)• VISY-Stick (filling level sensors)• Additional environmental sensorsVISY-Density (LPG) can be used only with the sensor VISY-Stick Advanced fromdevice number 40,000 onwards.To operate the VISY-Density (LPG) module, interface VI-4 with firmware 4.06or higher is required. The firmware version is displayed after the reset buttonof the VI-4 is pressed. The first three digits of the 7-segment display show theversions in succession (e.g. 4 – 0 – 6). For firmware below 4.06 please contactour service department for an update.To install the VISY-Stick Advanced probe with the VISY-Density module, there are 2 poss i-bilities:In fuel tanks the filling level sensor can be installed without any difficulty via a screw-inunit with external thread and also via the pipe installation (riser).Installation in LPG tanks is only possible with screw-in units.The sensors have to be connected with the VISY-Command evaluation unit which is to bemounted inside the petrol station building. Before operating, the VISY-Command must beconfigured using a PC or notebook and the VISY-Setup software application.The VISY-Command collects data from the sensors and transmits this to a higher-levelsystem (e.g. POS) on request.1.1 In this manual …… you are guided through the installation and commissioning as well as retrofitting of theVISY-Density module. |
