Rate Exception Control
Definition
•
Rate Exception Control is a method of quickly detecting a distur-
bance and changing operation from gravimetric to volumetric until
the disturbance has been eliminated.
•
Formula for determining when the HI 2160RC
PLUS
detects an REC
condition.
ROCSP x REC x 0.1 = DEV
ROCSP = Rate of Change Set Point (Desired Flow Rate)
REC = Rate Exception Control Level
DEV = Acceptable Deviation.
If the instantaneous "Rate of Change" (Flow Rate), exceeds the
acceptable deviation an REC condition will exist.
•
Example:
ROCSP = 5 pounds per minute
REC = 2.0 (20%) (Default Level)
