Page 121 2, 2, 8, 6, 1 Device dashboard DSP can be turned on or off. When on is selected, the Rosemount 8750W output is derived using a running average of the individual flow inputs. DSP is a software algorithm that examines the quality of the electrode signal against user-specified tolerances. This average is updated at the rate of 10 samples per second with a coil drive frequency of 5 Hz, and 75 samples per second with a coil drive frequency of 37 Hz.

By setting the time limit, you can force the Rosemount 8750W to clear the value of the running average and re-establish the output and average at the new flow rate once the time limit has elapsed. This parameter limits the response time added to the loop.
