Adjustment and functions
9.5.4. Setting the flow rate range
associated to the 4...20 mA output
The 4...20 mA output provides an electrical current, the value of
which reflects the flow rate measured by the device.
• The signal may be inverted, i.e. the flow rate value associated
to the 20-mA-current is lower than the one associated to the
4-mA-current.
• The current output gives a 22-mA-current when the device shows
an operating error.

FILT
The "Filter" function is used to attenuate the display and 4...20 mA
output, if any, fluctuations when the flow rate varies in the process.
Ten attenuation levels, from 0 (means no attenuation) to 9 (maximum
attenuation of the fluctuations) are available.
