Page 4: Overview
The VISY-Density (LPG) module is an extension of the VISY-Stick Advanced level sensor in the VISY-X system for the measurement of product/sump density of fuel or liquefied petroleum gas (LPG). The module is available for use in fuel tanks as "VISY-Density" and for use in LPG tanks as "VISY-Density LPG". -
Page 5: Requirements For Service Engineers
This manual contains a description of all steps needed for the implementation. Please also observe the additional instructions in the following manuals: Technical Documentation VISY-Command VI-4, art. no. 207184 Technical Documentation VISY-Stick and VISY-Reed, art. no. 207194 Requirements for service engineers The complete VISY-X system should only be installed by trained service engineers. - Page 6 When installing and servicing the sensors, the requirements of the Explosion Protection Regulations, the Industrial Health and Safety Regulations and the Equipment Safety Regulations as well as generally accepted rules of engineer- ing and these operating instructions must be observed. Observe also the the local safety and accident prevention regulations which are not stated in these operating instructions.

210 mm, the product density is determined (see Fig. 1). (9) Remove the transport locks (3 plastic pins) from the VISY-Density Module The float of the VISY-Density is protected by a transport lock, which consists of three lateral inserted plugs. The transport lock must be pulled out before oper- ating the VISY-Density. -
