Reliability study oval wheel meters and turbine meters demonstrates SIL 2

ZUG, Switzerland – – 1 december 2008 – – Risknowlogy®, a leading provider of risk, reliability, safety and certification solutions, announced today that it completed a reliability study on two different Vortex flow sensors of the VA series. The sensors are used for stationary measurements including in particle and condensation laden pressurized air gases.

Risknowlogy has performed a qualitative and quantitative reliability study on the meters. The reliability study consisted of a failure mode and effect analysis and markov study to quantify the functional safety attributes of the sensors. The results of the study are explained an a technical report including functional safety data sheets(tm). The functional safety data sheets(tm) hold the most important functional safety properties like SIL level, SFF, failure rates, MTTFs, MTTFd, and Diagnostic Coverage.

The following models have been addressed in the study: The two flow sensors are the VA40 … ZG7 and the VA40 … ZG8. For more information on the different meters we refer to the data sheets available on www.hoentzsch.com. The functional safety data sheets will be made available on the Functional Safety List.
