boiler water level gauge falling tube heat

Reasons why the water is bouncing in the gauge glass and ...

Jun 25 2014 · When the steam bubbles condense the water in the boiler falls to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. This usually turns on the low-water cutoff or the automatic water feeder. You wind up with nagging water level problems in the boiler. This type of problem is built into the boiler design and it's tremendously
