Water analyzer WA

Reliable boiler operation is dependent on good water  For sample preparation, flow coolers for boiler water
quality. The water analyzer continuously measures and and boiler feed water, as well as control valves for
monitors: switching and distributing each individual medium
 pH value of the boiler water  Flow rate indicator for visual inspection
 pH value, oxygen content and conductivity of the
boiler feed water The electronic component consists of:
 pH value and conductivity of the condensate or  Control unit including touch panel
steam accumulator water content  Power supply
 Electronics for the measuring modules
All data is transmitted to the system control SCO via  Communication processors for data exchange
the bus system. This means that all the key water between the water analyzer WA and system
parameters, including the conductivity of the boiler control SCO
water and that of the individual condensate flows, are
therefore available in the system control SCO. Benefits at a glance:
Demand-based control and monitoring tasks can be  Increase in operating safety thanks to continuous
performed fully automatically. If specified limit values monitoring of the water values
are exceeded, all parameters are transferred to the  Automated monitoring with constant measurement
fault message memory of the system control SCO. of the pH value, oxygen content and conductivity
Continuous logging of the data is also possible. The  Savings on chemicals thanks to needs-based dosing
data can be transferred via the bus system to a higher- of additives
level control centre, where it can be further processed.  Increased system efficiency through reduced desalting
losses and saving of exhaust vapour energy
Functions of the water analyzer are:  A water analyzer can monitor up to three boilers
 Infinitely variable control of the dosing system for  All the measured values can be transmitted via
oxygen binding agents Ethernet to the system control SCO or to the
 Infinitely variable control of the dosing system for customer's control centre, where they can be fully
alkalisation visualized
 Control of the exhaust vapour valve incl. visualiza-
tion of the exhaust vapour energy saved in kWh

Construction
The water analyzer consists of an analysis component
and an electronic component, both of which are
housed at the factory in two interconnected, wall-
mounted casings.

Equipment level
The analysis component contains the measuring
modules:
 pH control for measuring the pH value of the boiler
feed water and of the boiler water content for a
maximum of three boilers
 O 2 control for measuring the O 2 content of the
boiler feed water
 Conductivity sensor for measuring the conductivity
value of the boiler feed water
