Overview
Conductivity meters are used to measure the conductivity of boiler water, boiler feedwater and condensate so operators can track water quality and dissolved solids more accurately. That information supports boiler water treatment decisions, TDS monitoring, feedwater checks and wider boiler house instrumentation calibration. Spirax Sarco conductivity measurement solutions combine sensing and temperature compensation to give clearer readings across the operating conditions typically seen in steam boiler systems. A key practical advantage is that the conductivity sensor can be checked in operation without removing it from the boiler, helping reduce maintenance disruption. These products are commonly paired with automatic TDS blowdown controls where measurement needs to feed directly into continuous blowdown management rather than isolated manual testing.
Related boiler water control routes
Conductivity measurement becomes more useful when it drives a broader water quality strategy. Move into TDS blowdown controls when the measurement should feed automatic blowdown rather than manual checking alone. Use sample coolers when representative water sampling is also needed for on-site verification.
If the project is expanding into a wider instrumentation platform, continue into boiler level controls and the surrounding boiler controls.
Continue your boiler water control selection
Conductivity measurement is usually one part of a wider boiler water control approach. The next step is often automatic blowdown, safe sampling or broader control instrumentation.
Turn measurement into automatic control
Move into TDS blowdown controls when conductivity measurement needs to drive automatic boiler blowdown rather than manual checking alone.
Support safe manual water sampling
Use sample coolers when the job also requires representative boiler water sampling for on-site testing without flash steam affecting safety or accuracy.
Build a wider boiler instrumentation package
Review level controls when the wider boiler instrumentation scope also includes water level control, alarms and feedwater management.
