8.2 Intended use
The DID is designed for online monitoring of water quality
parameters and offers control functions for these parameters.
The DID must be used in accordance with the instructions given
in this manual. The values mentioned in this manual must be
observed.
8.3 Functional principle
The CU 382 control unit has a display and 7 operating buttons on
the front. The operating software starts automatically when the
CU 382 is powered-on.
The CU 382 control unit collects and displays readings from all
sensors via a digital bus connection. The CU 382 control unit
includes a PID (Proportional-Integral-Derivative) controller. With
the PID controller and dosing units, a closed control loop can be
set up.
The hydraulic part of the DID manages the complete water flow
from the inlet to the outlet. This includes filtration, pressure
reduction, flow restriction and flow control. The DID comprises
specifically designed flow cells for mounting of the sensors and
appropriate sampling.
