Steam drum level is both a critical and difficult measurement to take as control of the water level in the drum must be precise.

A water level that is too high can result in water carryover into the steam piping. A level that is too low can expose the generating tubes (down comers), preventing the water in the drum from cooling the furnace tubes properly and possibly damaging them. Several factors make this measurement difficult to obtain. The steam drum itself may not be perfectly level, and even at steady state conditions, considerable turbulence in the drum can cause the level to fluctuate. Constantly changing rates of water inflow and steam outflow add to the potential for measurement error.

Our solution provides accurate and reliable measurements of liquid level even when the operating environment includes mechanical vibration and high turbulence.

The Emerson Rosemount™ Level Transmitter - Guided Wave Radar provide an alternative for steam drum level measurement as they offer a number of important advantages over differential pressure and level technology. These transmitters measure level in a way that is completely independent of liquid density, so the complexity of density compensation is not required. Further, these transmitters are able to measure level at temperatures up to 400°C and pressures up to 345 bar. They provide accurate and reliable measurements of liquid level even when the operating environment includes mechanical vibration and high turbulence.
