High Calibration Point
Distance from Sensor Reference Point to High Calibration Point: usually process full
level.
Value
Low Calibration Point
Distance from Sensor Reference Point to Low Calibration Point: usually process
empty level.
Value
Response Rate
Sets the reaction speed of the device to measurement changes in the target range.
Notes:
• Response Rate can only be set through the Quick Start Wizard, and any
changes made to Fill Rate per Minute (2.3.1.) or Empty Rate per Minute (2.3.2.)
parameters following the completion of the wizard will supersede the Response
Rate setting.
Response Rate
•
Options
Use a setting just faster than the maximum filling or emptying rate (whichever is
greater). Slower settings provide higher accuracy, faster settings allow for more level
fluctuations.
Calculation factors:
Notes:
• The following five parameters will display in the wizard based on the PMD
selected above.
• These parameters are used in the flow calculation formula (see full Operating
Instructions for details).
Flow Exponent
(PMD = EXPONENTIAL DEVICES)
The exponent for the flow calculation formula.
