Boiler and Cooling Water Monitoring
Routine measurements help treatment teams manage concentration, corrosion risk and chemical-treatment performance.
Why digital measurement matters
Conductivity and TDS are commonly used to assess cycles of concentration and blowdown. pH indicates acid or alkaline condition. ORP assists oxidising-biocide monitoring. Dissolved oxygen is important where oxygen corrosion or aeration performance is relevant. Portable meters support plant rounds, while online meters and controllers provide continuous process visibility.
Recommended measurement workflow
- Define the decision the result must support.
- Identify the parameter, expected range and required resolution.
- Select a suitable meter, sensor and calibration standard.
- Collect a representative sample or confirm the online installation point.
- Calibrate, rinse and condition the sensor according to the manual.
- Allow the reading to stabilise and record temperature and calibration status.
- Investigate unexpected trends and confirm critical results when necessary.
Sampling
Use clean containers and representative locations. Avoid aeration or contamination where it could change the parameter.
Calibration
Use fresh standards, appropriate calibration points and a frequency suitable for the importance and stability of the measurement.
Maintenance
Clean sensors carefully, store them correctly and replace consumable membranes, electrolytes or electrodes when performance declines.
