STEAM DRUM WATER LEVEL …

The water density in the external instrument is higher than the steam drum water density. The external measurement instrument will always indicate lower than the True Drum Level. The magnitude of the level error depends on operating pressure and height of the water column. The density of boiler water decreases as operating pressure increases.

Methods of Detecting Water Level in Steam Boilers | Spirax

The differential pressure cell is installed with a constant head of water on one side. The other side is arranged to have a head which varies with the boiler water level. Variable capacitance, strain gauge or inductive techniques are used to measure the deflection of a diaphragm, and from this measurement, an electronic level signal is produced.

Boiler Water Level Control System Example | Introduction

Oct 31, 2019 · An important variable to measure and control in a continuous boiler is the level of water in the "steam drum" (the upper vessel in a water-tube boiler). In order to safely and efficiently produce a continuous flow of steam, we must ensure the steam drum never runs too low on water, or too high.
