The DULCOMETER
AEGIS II is a Multi-parameter
control and analysis platform from ProMinent. In the
remainder of this document, the term 'controller' is
consistently used for the DULCOMETER® AEGIS II.
The controller has been developed for continuous
measurement and control of liquid analysis
parameters in water treatment processes in industry.
The controller can operate together with
conventional analog and digital sensors and
actuators. The controller is also equipped to
communicate with some sensors using a proprietary
serial bus.
The controller relays may be used with solenoids,
chemical metering pumps and related water
treatment equipment, not to exceed 1 amp each.
(Typical)
Typical applications:
Cooling water treatment
Data and event logger
Boiler water treatment
Industrial process water treatment
Potable water treatment
Waste water treatment
pH and/or temperature compensation for
free chlorine measurement
Standard equipment:
Two serial input channels for use with CTFS
(Conductivity/ Temperature/Flowswitch
Serial), dual serial corrosion rate sensors or
DP (differential Pressure) sensors.
Eight multi-purpose digital inputs (2 NAMUR
- Intrinsically safe¹) for turbine and contact
water meters and limit switches.
One 4-20mA analog input
One analog temperature input.
Temperature compensation for the pH and
conductivity sensor signals.
Output Relays: On-Off, Time Modulated
(Pulse Width Modulation) or PID controller
using any/all of the following: line voltage
relays(2), unpowered 'dry' contacts(3), or
Solid State DC contacts(4).
Currently, 1 operating language
Saving and transfer (cloning) of controller
configuration via USB.
Upgrading of the firmware function using
USB Flash Drive
Ethernet LAN connection for remote
operation or configuration
Optional accessories:
Up to 3 dual sensor input/output driver cards
including:
Dual pH/ORP, Single pH/ORP with
temperature and 4-20mA input, Boiler
Conductivity, Conductivity/Temperature,
Dual 4-20mA Output, Dual 4-20mA input or
a Dual Serial Input driver.
A full line of ProMinent sensors as well as
signals from most 4-20mA devices are
compatible with the 4-20mA input. Sensors
include: Chlorine, Bromine, Peracetic Acid
(PAA), Toroidal Conductivity and
fluorometers.
