The water level height indicated by the primary water level gauge is higher than the actual water level height of the steam drum (B) A. Be high. B. Be low. C. equal. The pressure inside and outside the drum is the same. Because the temperature inside the drum is high and the density of the medium is low, the liquid level is higher than the water level gauge.
