Water Columns and Standpipes are primarily used to support Water Gage Glasses. Water Columns are available in cast iron models for applications to 250 PSI (17 Bar) and steel models for applications up to 3000 PSI (207 Bar). Water Columns generally include conductivity probes for High & Low Alarms and Low Water Cutout functions. Standpipes support Water Gage Glasses, the same function as a Water Column, without probes. A Water Column or Standapipe provides the proper support for mounting a Water Gage Glass and assures stable observation of the drum level. An Electrolev Column may serve as Water Column to support a Water Gage Glass. This combination forms a “LevelMax” System for remote and local level indication in one assembly.
