Install an Automatic Blowdown-Control System

2017-6-3 · With an automatic blowdown-control system, high- or low-pressure probes are used to measure conductivity. The conductivity probes provide feedback to a blowdown controller that com-pares the measured conductivity with a set-point value, and then transmits an output signal that drives a modulating blowdown release valve.
