1)
Ultrasonic measurement requires that the sound wave travel through the atmosphere in a
2)
consistent manner. Applications with atmospheric conditions different from air (including,
but not limited to gas layer stratification, very high methane or CO
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.
A high accuracy configuration consists of the device using XRS-5 transducer, TS-3
3)
temperature sensor, and a lower calibration point of 3 m or less.
Achieved with a 100 μs shot width

Memory card functions support
Only the supplied microSD card is supported for backup, restore, logging, and firmware
