Monitoring conductivity in boiler water is essential because it indicates the presence of dissolved solids in the water. Conductivity is a measurement of how well water can conduct an electrical current, which is affected by the concentration of ions in the water—primarily those from dissolved salts and minerals. A higher conductivity reading usually correlates with a higher concentration of these dissolved solids, which can include harmful substances like salts and contaminants that can lead to scale formation and corrosion.

In a boiler system, maintaining appropriate levels of dissolved solids is crucial for operational efficiency and longevity. High levels of these solids can result in scaling on heat transfer surfaces and negatively impact boiler performance. Therefore, monitoring conductivity serves as a way to assess the overall water quality in the boiler, ensuring that it remains within acceptable limits to prevent damage and maintain efficiency.

This focus on dissolved solids distinguishes conductivity monitoring from other aspects like pH level assessment, temperature measurement, or hardness determination, which relate to different characteristics of water quality. Each of those other methods serves its purpose, but they do not directly provide the same insight into dissolved solids as conductivity measurements do.
