2 INTRODUCTION
2.1 PRELIMINARY REMARKS
The 9092 Chlorine Analyzer is used for automatic, continuous measurement of dissolved free
chlorine (Cl2) in aqueous media. The analyzer is used for process monitoring and control, and to
provide an alarm when limits are exceeded. Applications might include process water treatment,
drinking water treatment and water management in swimming pools.
It should be noted that the free Cl2in pH depend value (see figure) relates to hypo-chlorous acid
(HOCL Hypochlorite) and it’s anion.
An acidic environment is preferable, because the hypochlorite ion HOCL acts significantly less
micro-bicidal than hypochlorite and hypo-chlorine-free. Important for the correct implementation
of the disinfection process is an accurate, exact stoichiometric dosage of the required chlorine. By
measuring the presence of residual chlorine, the required concentration surplus for a safe
disinfection can be maintained.
Monitoring free chlorine levels is also important because chlorine can react with organic
substances and ammonia, whereby the amount of available free chlorine fore killing bacteria can
be reduce considerably. Furthermore, in the reaction of chlorine with organic compounds
secondary products are formed, which can be hygienically dangerous (Chloramine).
2.2 WORKING PRINCIPLE
During the measurement of the dissolved chlorine, the sample flows through a coaxial designed
measurement cell by a gold measuring electrode. The electrochemical sensor functions is a
potentiostatic mode with an open three-electrodes system (no Membrane). Consequently, exact
and reliable measurements can be accomplished at pressures and in areas where pressure spiking
take place. This sturdy and reliable measurement system makes it possible to operate accurately
even under harsh conditions.

3 INSTALLATION
3.1 RECEIVING
The Waltron 9092 Chlorine Analyzer is assembled and fully tested for proper performance.
Before proceeding with analyzer installation, it is recommended to:
Check that the box and analyzer have not been damaged during transportation.
Take extreme care during analyzer unpacking and moving.
Be careful not to misplace accessories during unpacking. Refer to the packing list
included.
3.2 ANALYZER HANDLING
Take extreme care when lifting or moving the analyzer. Before moving the analyzer, it is
recommended to manually empty all of the hydraulic parts of any liquids.
3.3 LOCATION AND MOUNTING
It is recommended to install the analyzer in a suitable position:
The location is to be clean, covered and properly enclosed to provide the analyzer with
good ventilation and low dust concentration.
Operating environmental conditions are: temperature between 5 and 50°C at max 80%
relative humidity. If the temperature is below 5°C, the analyzer should be installed in a
heated cabinet.
Place the analyzer close to the sample point to achieve the minimum response time; the
sample should be homogenous and representative.
The drain line should be properly dimensioned and positioned at a downward slope to
allow the drain of analyzed sample (by gravity).
WARNING!
The sample drain of the analyzer must be at ambient
pressure with no restriction or counter pressure.

3.6.1 TRANSMITTER ENCLOSURE
The electronics are housed in the transmitter enclosure which has a protection rating of IP67. In
order to maintain that level of protection, all communications and power cables passing through
the transmitter enclosure must use the appropriate cable glands.
To gain access to the terminal block connections for power and communications, the lower panel
on the front of the transmitter can be removed by unscrewing the six screws holding the panel in
place.
