Functional description

The DULCOMETER
Multi-parameter Controller diaLog DACa
is a controller platform from ProMinent. In
the remainder of this document, the term
'controller' is consistently used for the
DULCOMETER ® . The controller has been
developed for continuous measurement
and control of liquid analysis parameters.
For water treatment processes in environ‐
mental technology and industry. The con‐
troller is available in versions with one and
two measurement channels. The con‐
troller can operate together with conven‐
tional analog sensors and actuators. The
controller is equipped to communicate
with digital sensors and actuators via the
CANopen sensor/actuator bus.
