monitoring the flow rate in the pipe

A malfunction in your process or of the flow sensor may be indicated
either by a flow rate which is too low or too high.
The parameter "FLOW-W." makes it possible to monitor the flow
rate.
• To disable the flow rate monitoring, set W- = W+ = 0.
• To disable one of the limits, set it to 0.
To be warned when the flow rate is too low or too high, enter the
flow rate range (in the units that have been chosen in the "UNIT"
parameter of the Parameters menu), outside which the device gen-
erates a warning message, "WARN LO" or "WARN HI", and turns
the device status LED to orange.
