Response Rate
Sets the reaction speed of the device to measurement changes in the target range.
Note
• Response Rate can only be set through the Quick Start Wizard, and any changes made to
Fill Rate per Minute (2.3.1.) (Page 178), Empty Rate per Minute (2.3.2.) (Page 178), or
Damping Filter (2.3.3.) (Page 178) parameters following the completion of the wizard will
supersede the Response Rate setting.
• Response Rate always displays in m/minute.
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 rapid level
fluctuations.
Calculation Factors
Note
• 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 Method of Flow
Calculation (Page 306)).
