Conductivity, sometimes expressed as ppm TDS (parts per million total
dissolved solids), is the method used to monitor mineral concentration. Many
industrial boilers use periodic grab sample conductivity measurements and
manual setting of the blowdown rate. This results in large swings in mineral
content between grab sample measurements caused by changes in boiler
load, make up water quality, etc. that can cause periods of scaling, corrosion
or excessive blowdown.
A much improved strategy uses a continuous on-line conductivity measurement and automatic blowdown
control to maintain consistent mineral concentration and minimize corrosion and scaling under all
conditions. The Mettler Toledo Boiler Conductivity Sensor with its high temperature/pressure rating allows
continuous measurement directly in the blowdown line without the expense of a sample cooler or cooling
water flow for samples up to 250 psig (17 bar) at 392 °F (200 °C).
The Mettler Toledo Boiler Sensor combined with a M300 transmitter, provides a
continuous, accurate conductivity measurement with readout in µS/cm, mS/cm or
ppm TDS. The transmitter can be located up to 200 ft (61 m) away from the sensor
and retransmit alarm, control and/or analog signals even further. Automatic
blowdown control allows close management of boiler water quality and usually
reduces the amount of blowdown, saving a significant amount of energy.
