Selection of the boiler drum type level indicator
The boiler is a high-temperature high-force container, which is a relatively dangerous device. Once the high temperature and high force steam leaks, it is easy to cause personal injury. The level gauge used on the boiler steam drum is a key equipment of the boiler. The liquid level in the steam drum

Density Compensation for Steam Drum Level
2019-10-23 · Drum level is frequently also measured by Eye-Hye – a device like a sight glass with relays to indicate whether each point (separated by an inch or two) has water or not.Because the temperature of the water in the Eye-Hye is colder and more dense than the water in the drum, the water in the Eye-Hye tube will be several inches lower than the level in the drum when at high temperatures.
