Rate Parameters (P700 and P701)
These parameters determine how material level changes are reported.
P700 Maximum Fill Rate
Adjusts the SITRANS LR 300 response to increases in the actual material level (or an
advance to a higher Fail-Safe Material Level, P071).
Enter a value slightly greater than the maximum vessel-filling rate. This value, in Units
(P005) or % of Span (P007) per minute, is automatically altered when Maximum Process
Speed (P003) is altered.
P701 Maximum Empty Rate
Adjusts the SITRANS LR 300 response to decreases in the actual material level (or an
advance to a lower Fail-Safe Material Level, P071).
Enter a value slightly greater than the vessel’s maximum emptying rate. This value, in
Units (P005) or % of Span (P007) per minute, is automatically altered when Measurement
Response Speed (P003) is altered.
