5 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.
Typical applications:
n Potable water treatment
n Waste water treatment
n Industrial and process water treat‐
ment
n Swimming pool water treatment
Standard equipment:
n One measuring channel with 14 freely
selectable measured variables (via
mV or mA input)
n PID controller with frequency-based
metering pump control for 2 metering
pumps
n Two analog outputs for measured
value, correcting value, or control var‐
iable (dependent on the optional
equipment)
n Two digital inputs for sample water
error identification, pause and param‐
eter switching
n Two relays with limit value function,
timer and discontinuous control, 3-
point stepper control (dependent on
the optional equipment)
n Measured variables and language
selection during commissioning
n Temperature compensation for the pH
and fluoride measured variables
n 22 operating languages
n Saving and transfer of device para‐
metrisation using an SD card
n Retrospective upgrading of the soft‐
ware function using activation key or
firmware update
n Disturbance variable processing
(flow) via frequency
n Measured value trend display via the
controller display
Optional accessories:
n Second, complete measuring and
control channel with 14 freely select‐
able measured variables (via mV or
mA input)
n PC configuration software
n Data and event logger with an SD
card
n Disturbance variable processing
(flow) via mA
n Compensation of the pH influence on
chlorine measurement
n 3 additional inputs, e.g. for level moni‐
toring
n PROFIBUS
®
-DP *.
n Modbus-RTU
n Visualisation via LAN/WLAN web
access
