General

Compact, intelligent and reliable Advanced Tank Gauge. As tank gauging has evolved, the series 854 ATG servo level gauge has become an industrial standard all over the world. Very reliable, versatile and accurate automatic tank gauge with a minimum of moving parts, meeting all international standards, regulations and recommendations. The multi-functional instrument is modularly constructed. The servo 854 is equipped with a Servo Auto Test feature which further increases the safety integrity of the servo and increases the diagnostic coverage. That means that the Servo can be used in overfill protection loops to prevent spillage. What is unique about this SIL-2 solution is the fact that all installed servo 854 worldwide can be simply loaded with a software add-on that allows it to be used in SIL-2 safety rated loops. The increased diagnostics in the gauge will detect failures inside the gauge or in the application and report this to higher level systems for further action. With the added diagnostics, the safety proof-test interval can be extended to 5 years. This will significantly bring down the operational cost compared to other solutions that require a proof test to be carried out every year.

The 854 Servo level gauge has a SFF (Safe Failure Fraction) > 90% which allows it to be used in SIL-2 safety loops. If used in redundant configuration, the servo 854 ATG can be used in SIL-3 rated loops.
