Note
Operation under special atmospheric conditions
Ultrasonic measurement requires that the sound wave travel through the atmosphere in a
consistent manner. Applications with atmospheric conditions different from air (including, but
not limited to gas layer stratification, very high
methane or CO
2
concentrations), should be
properly assessed to ensure safe reliable use in the event of measurement errors due to
sound wave velocity changes. Please contact your local Siemens representative for
assistance.
