MEASUREMENT PARAMETERS (P920 to P923)
Use these parameters to verify Application Parameter programming, when performing a dynamic material
level test over at least 2 empty/fill cycles for each vessel is impractical.
Access the following parameters to take an ultrasonic measurement and automatically:
» display the corresponding Reading in the Parameter Value field.
» set the mA output value accordingly.
» set the relay status accordingly.
» transmit the corresponding point data to the BIC-II (if used).
If measurements or simulation are desired, however DPL+ operation
has not been verified, disable all associated process control equipment
before accessing the following parameters.
To take an ultrasonic measurement, access one of the following parameters and...
(repeat 5 times to overcome Echo Lock, P711).
Alternatively, to simulate a rising and falling material level. During the simulation, the DPL+ will
operate as though the material level was repeatedly cycling from full to empty to full, and so on, at a rate of
1% of Span (P007) per second. See Lock (P000) to activate control relays during simulation.
The simulation starts at level = 0, unless a specific level value was entered beforehand.
to switch to the rising (or for the emptying) simulation as required. Holding the key
increases (or decreases) the simulated rate of rise (or fall), to 4% of Span per second.
to end the simulation, when desired.
During a measurement or simulation, the DPL+ display responds as though in the RUN mode, however the
value displayed in the Reading field is affected by the Measurement Parameter selected, and the material
level is displayed in the Auxiliary Reading field.
P920 READING MEASUREMENT
The Reading corresponds to all associated programming.
P921 MATERIAL MEASUREMENT
The Reading corresponds to the distance between Empty (P006) and the material level.
P922 SPACE MEASUREMENT
The Reading corresponds to the distance between the material level and Span (P007).
P923 DISTANCE MEASUREMENT
The Reading corresponds to the distance between the material level and the transducer face.
P924 VOLUME MEASUREMENT
The Reading corresponds to the volume calculation in percent of Max Volume (P051).
as required to display in Max Volume units.
