a length of pipe mounted onto a vessel that supports the flange.

in programming, variables that are given constant values for specific purposes or
processes.
a wave that departs from an initial level for a limited duration of time, and returns to the
initial level.
when configuring SITRANS Probe LU with Step 7, the Probe LU has a virtual "rack" to

distance between a transmitter and a target.
the closeness of agreement among repeated measurements of the same
variable under the same conditions.
one transmit pulse or measurement.
a pipe that is mounted inside a vessel parallel to the vessel wall, and is open to the
vessel at the bottom.

which echoes are determined to be valid.
having a frequency above the human ear's audibility limit: about 20,000 hertz.
difference between a current measurement and the benchmark value separating the
startpoint and endpoint of, for example, device lifetime. If the current value is less than
the benchmark, it indicates a 'wear' . This does not have to be measured in time: it could
be, for example, the percentage loss of a protective coating.
