What does an automatic blowdown controller monitor?

An automatic blowdown controller is specifically designed to monitor water conductivity in a boiler system. The primary purpose of monitoring water conductivity is to assess the concentration of impurities in the boiler water. High levels of dissolved solids can lead to scaling and corrosion, which can adversely affect the boiler's performance and efficiency.

By measuring water conductivity, the controller can determine when the dissolved solids concentration exceeds a predetermined level. This information allows for timely blowdown actions to remove a portion of the concentrated water, maintaining water quality and preventing damage to the boiler. Automated systems can optimize blowdown rates, ensuring that the boiler operates efficiently while minimizing water and energy waste. In this context, monitoring water conductivity is crucial for effective boiler management and long-term operational reliability.
