WebMaster®ONE
WebMasterONE is the most advanced online cooling tower
and boiler controller in the water treatment industry. The
flexible multi-I/O platform allows you to control multiple
cooling towers, boilers, closed loops, and condensate lines
with just one controller. An extensive assortment of integrated
communications and data handling features are included
that enable water treatment professional to provide more
effective water management services to their customers.

Metering Pumps
The E-Class is the most innovative and comprehensive
metering pump product line in the world. Over 50 years of
pump experience and a commitment to superior mechanical
design has led to development of many industry firsts, including
360 stroke-per-minute technology, IP67 waterproof construction,
and the world’s highest capacity solenoid metering pumps.
Sensors (Select 2 in alphabetical order for WDEC)
N t= tNo sensorttt
Four conductivity ranges may be selected to configure the controller over a wide
range of applications. Choice of measurement units is µS/cm, mS/cm, ppm and
% concentration. The non-contacting, toroidal sensor technology is immune to
thin coatings and the contamination and calibration problems that direct contacting
sensors are prone to.

Summary of Key Benefits
Dual Input Reduces Cost
WDEC can accept two electrodeless conductivity sensor inputs, allowing one controller to take the
place of two, reducing cost and space requirements, and simplifying installation.
Versatility for a Broad Range of Applications
Choose PEEK sensors for higher temperature, more aggressive chemical applications, or CPVC sensors
for lower temperature, less aggressive chemical applications. Both are available for in-line or submersible
applications. On/Off and Time Proportional control modes are menu selectable.

The WEC/WDEC410 Series Single and Dual Input Electrodeless Conductivity
Controllers measure conductivity of a solution via an encapsulated, noncontacting sensor to control replenishment pumps and alarms. They may be
installed in a variety of very harsh chemical control applications, including oily
cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated
chemicals up to a conductivity of 1000 mS/cm.

Ideal for Harsh Environments
The rugged, NEMA 4X enclosure, combined with Walchem’s electrodeless conductivity sensors, provides
a waterproof system with no metallic parts exposed to wet or corrosive environments.
Built-in Safety Features
Programmable output limit timers prevent run-away chemical addition. Digital Interlock Input may be
used from a flow switch or level input to prevent chemical addition based on a stagnant sample, or
control of an empty tank. The alarm relay notifies plant personnel of alarm conditions as soon as they
occur.
Simple, Integrated Data Collection
Download stored data from the controller to a USB stick with the press of a button. Use the data to
simply and easily validate system performance, document compliance, and reduce liability. The data and
event logs show conductivity and temperature values, as well as accumulated chemical feed and alarm
relay activation times.
