Abstract
A liquid level measuring system for the steam drum of a steam generator employs a plurality of bubblers spaced along the length of the drum to obtain a level profile. The steam pressure to the bubblers is supplied by tubes connected to the steam/water inlet space which has a pressure significantly higher than the steam space in the drum. Horizontal pressure taps on each bubbler transmit the pressure to pressure cells external to the drum where the bubbler pressure is compared to the pressure in the steam space. These reading can then be converted to liquid level readings.
