Limit

The time limit parameter forces the output and running average values to the new value of
an actual flow rate change that is outside the percent limit boundaries. It thereby limits
response time to flow changes to the time limit value rather than the length of the running
average. If the number of samples selected is 100, then the response time of the system is
10 seconds. In some cases this may be unacceptable. Setting the time limit forces the
transmitter 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. A suggested time limit value of two seconds is a good
starting point for most applicable process fluids. This parameter can be configured for a
value between 0.6 and 256 seconds. The default value is 2 seconds.

An example plotting flow rate versus time is given below to help visualize the signal
processing algorithm.
