Electrode system control unit

Type EL 1

It is advantageous to use, in particular, to signal the achievement of the set levels of the liquid level, as an input member of a downstream control system that further processes and controls the respective aggregates. The EL 1 type does not include a memory member and immediately supplies with an adjustable time delay information about flooding or stripping of the independent electrodes 11, 21.

Type EL 2

It is advantageous to use for direct control of the unit, for example, pumps with two different modes of operation:

Mode 1 = draining liquid from the tank.

Mode 2 = pumping liquid into the tank
