Milltronics AIRANGER DPL PLUS - MEASUREMENT RESPONSE

MEASUREMENT RESPONSE
The DPL+ Measurement Response (P003) to material level changes is designed to exceed the most
demanding installation requirements.
The Measurement Response setting automatically adjusts various parameters affecting the DPL+ response to
material level changes as follows:
* Scan Delay (P727) is globally set for all Point Numbers to the value associated with the
fastest Measurement Response (P003) selected for Point Number 1or 2.
If any of these parameters are independently altered, a Measurement Response parameter alteration
automatically changes the independently altered value.
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 DPL+ 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 DPL+ 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...Distance Measurement (less than 60 m).
EXAMPLE 4...Dual Point Differential.
EXAMPLE 5...Dual Point Average.
EXAMPLE 6...Tripper (Equipment Position Monitoring, greater than 60 m).
