The Measurement Response setting automatically adjusts various parameters affecting
the XPL Plus response to material level changes as follows:
If any of these parameters are independently altered, a Measurement Response
parameter alteration automatically changes the independently altered value.
* Scan Delay (P727) is globally set for all Point Numbers to the value associated with the
fastest Measurement Response (P003) selected for any individual Point Number.
Slower Measurement Response provides greater measurement reliability. Faster
independently set Max Fill / Empty Rates may be impeded by Echo Lock, Scan Delay
and Shot Delay values.
Application Examples
The following examples describe the use of XPL Plus programmable features, to meet the
needs of specific process measurement requirements.
It is highly unlikely that your specific installation will match one of these examples
exactly.
However, by reviewing the example (or combination of examples) that matches your
installation best, the relationship between XPL Plus features and process measurement
requirements may be more easily recognized.
EXAMPLE 1. Level (or Material Volume) Measurement for a single vessel.
EXAMPLE 2. Space (or Remaining Vessel Capacity) Measurement for a single vessel.
EXAMPLE 3. Multi-point Average
EXAMPLE 4. Distance Measurement (less than 60 m).
