1 Introduction The VISY-Density module is an extension of the level sensors VISY-Stick Advanced / Flex for measuring the product / sump or in the LPG version for measuring the product density of liquefied petroleum gas (LPG). The VISY-X system (Volumen Information SYstem) provides highly precise and continuous level measurements for all commercially available fuels including LPG in up to 16 tanks.
1.2 Safety instructions The VISY-X system is optimised for use in petrol stations and can be used for all commer- cially available fuels and liquefied petroleum gas. It serves to measure and evaluate the filling levels in tanks. Use the system exclusively for this purpose. Observe and follow all product safety notes and operating instructions.
2 VISY-Density and VISY-Density LPG The VISY-Density module is available for use in fuel tanks as "VISY-Density" and for use in LPG tanks as "VISY-Density LPG". 2.1 Design and construction VISY-Density and VISY-Density LPG differ in the module length and the measuring range...
VISY-Setup software application. 3.1 Scope of delivery VISY-Density and optional additional floats are supplied in a box separated from the level sensor. It must be mounted on the probe tube of the level sensor on site. The module and probe are...
4th With the VISY-Stick Advanced, slide the spacer onto the probe tube 5th Slide the VISY-Density module with the designation in direction of the probe head onto the probe tube 6th Slide the water float (option) with the top marking in the direction of the probe...
8th c) For VISY-Density LPG: mount the module at the lower end of the probe tube 9th Remove the transport locks (3 plastic plugs inserted laterally) from the VISY- Density Module 3.2.2 VISY-Density with VISY-Stick Flex VISY-Stick Flex must not be bent during assembly apart from the straightening when installed in the tank.
8th Using an Allen key, turn the setscrews of the weight in the groove of the probe tube until the stop is reached. 9th Depending on the application, fix VISY-Density at the appropriate height of the probe tube with the 2 setscrews (see Figure 1: VISY-Density and VISY-Density LPG:...
An existing VISY-Stick Advanced, VISY-Stick Advanced LPG, or VISY-Stick Flex level sensor can be retrofitted with a VISY-Density module. The level sensor must be updated on-site with the calibration data of the VISY-Density module with the aid of a PC/laptop.
VISY-Density module is more than 215 mm 4th c) For VISY-Density LPG: mount the module at the lower end of the probe tube The VISY-Density module must not be fixed to the corrugated hose of the VISY-Stick Flex probe.
The level sensor must not be programmed in the installed state or in the potentially explosive environment. Plug the FAFNIR USB adapter into a free USB port on the PC (the PC must have Internet connection to install the drivers), see also: ...
Before installation, move the floats down as far as possible on the probe tube to prevent them from falling and being damaged when the probe is erected. The transport lock of the VISY-Density module (3 plastic plugs inserted laterally) must be removed before installation.
5.2 Return shipment Before returning any FAFNIR equipment, the Return Material Authorization (RMA) from FAFNIR customer service is required. Please contact your account manager or the custom- er service to receive the instructions on how to return goods. The return of FAFNIR equipment is possible only with authorization by the FAFNIR customer service.
