Hazardous area
Hazardous area
An area with a potentially explosive atmosphere. Trained personnel can
install and use an instrument in this area. The instrument must be ordered
with the appropriate options. The device requires approvals (ATEX, IEC Ex,
FM, CSA, NEPSI etc.) related to site specifications. You can find more data

Interface level
This is a display option. It is the height from the bottom of the tank (user-
defined) to the interface (or tank height - interface distance). See the

Measurement pulse
The instrument transmits a short, low-powered electrical pulse or wave
transmitted down a guide to the process. The process (or the probe end if
in TBF measurement mode) reflects the pulse back to the instrument.
