Parameters
2.4.2. Fill Rate
Defines the maximum rate at which the reported sensor value
1)
is allowed to
increase. Allows you to adjust the SITRANS LR250 response to increases in the
actual material level. Fill Rate is automatically updated whenever Response
Rate is altered.
Enter a value slightly greater than the maximum vessel-filling rate, in units per
minute.
2.4.3. Empty rate
Defines the maximum rate at which the reported sensor value
2)
is allowed to
decrease. Adjusts the SITRANS LR250 response to decreases in the actual
material level. Empty Rate is automatically updated whenever Response Rate
is altered.
Enter a value slightly greater than the vessel’s maximum emptying rate, in units
per minute.
1)
The value produced by the echo processing which represents the distance from sen-
sor reference point to the target (see Sensor Mode (2.2.2.) on page 79 for an illustra-
tion).
