Current Output; Pulse Output - Burkert 8025 Manuel Utilisateur

Adjustment and functions
5.3.4.

Current output

This function makes it possible to modify the default flow rate range associated to the
4-20 mA current range. Usually the minimum valu of the flow rate range is associated to the
4 mA current and the maximum value of the flow rate range to the 20 mA current, for ins-
tance the flow rate range 0 to 180 l/min corresponds to the 4-20 mA current range.
The current output can however be inverted by inverting the flow rate range. Associate the
maximum value of the flow rate range to the 4 mA current and the minimal value of the flow
rate range to the 20 mA current: The flow rate range 0-180 l/min, for instance, then corres-
ponds to the 20-4 mA current range.
The units and number of decimal digits are those set within the "UNIT" function.

If you do not want to adjust another parameter, go to the "END" parameter of the Set-
tings mode and press the "ENTER" key to save the settings and go back to the Read
mode.

Pulse output

This function makes it possible to input the volume of liquid corresponding to a pulse.

Choose the unit then input the volume.
Example: a pulse is emitted every 5 m
