Measurement (P920 to P927)

Use these parameters to verify programmng, when performing a dynamic material level test over at least 2 empty/fill cycles for each vessel is impractical. The parameters below will display the corresponding Reading in the Parameter Value field, will set the mA output value accordingly, and will set the relay status accordingly.

Note: If measurements or simulation are desired, but the LU01 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 press (repeat five times to overcome Echo Lock, P711).

Alternatively, press ENTER to simulate a rising and falling material level. During the simulation, the LU01 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 was entered.

Press to switch to the rising (or for emptying) simulation as required. Holding the key increases (or decreases) the simulated rate of rise (or fall) to 4% of Span per second.

Press to end simulation.

During a measurement or simulation, the LU01 responds as though in the RUN mode, but the value displayed in the Reading field is affected by the Measurement Paramter selected, and the material level is displayed in the Auxiliary Reading field.

P920 Reading Measurement

Corresponds to the final reading after all programming is applied.

P921 Material Measurement

The distance in Units (P005) or % of Span (P007) between Empty (P006) and the monitored surface.

P922 Space Measurement

The distance between the monitored surface and Span (P007).

P923 Distance Measurement

The distance between the monitored surface and the transducer face.
