filling is completed to 'D'. The parameter ‘I’ is the switch point for lower speed and ‘H’ is the target
volume. ‘E’, ‘F’ and ‘G’ are alarm and emergency shutoff values.

As a rule, valves don't close directly and completely. It comes to vibrations if the liquid is suddenly
stopped. The vibrating amount of liquid is measured. If the oscillation amplitude is in a
programmable area for a predefined number of measuring, then the filling is regarded as ended.

In addition to the described functions alarm and emergency off functions can be programmed. The
individual phases of the filling process, changes of state and the filling results can be sent by the
device automatically. The Krohne configuration program represents a good summary of the
possibilities for the BATCHCONTROL 5014C.
If the possibilities shouldn't suffice, then customer specific functions can be down loaded in the
device.
