Zero cut off (m/s)
The instrument has an automatic ZERO CUTOFF that is calculated to 0.05 m/s. The maximum flow is calculated when the
instrument is programmed and is displayed when sensor set and mode of operation are displayed (See 3.10 - Read Flow - Attach
sensors).
KROHNE cannot guarantee measuring flows below this range because of instabilities in measuring,
but it is possible for the user to cancel any cut-off altogether.
This also allows the user to not see or record any flow that they may not want to. For example it may be that the user may not
want to measure flows below 50 LPM in a 50mm pipe which is equivalent to 0.42 m/sec, in which case 0.42 m/sec would be
entered into the instrument and nothing would be recorded below that level. The maximum cut off 1 m/sec.
