Purpose of water column:
When steaming, boiler water is in constant, turbulent, violent motion. If a glass attached direct to the boiler, the water would oscillate up and down so rapidly that an accurate reading would be difficult at best. The construction and placement of a water column averages out these wild gyrations, providing a stable water level allows the gauge glass and other devices to yield accurate reading.
