APPARATUS FOR CONTINUOUSLY MONITORING LIQUID LEVEL CONDITIONS IN A LIQUID-VAPOR SEPARATING DEVICE |
摘要 |
An apparatus 100 for providing information concerning a condition of a vessel such as a steam drum 12 which segregates steam and liquid from one another includes a liquid contact assembly 102, a signal generator element 130, and a housing 112 and a conduit 114 for enclosing the signal generator element 130 in a substantially leak proof manner within the vessel space. The liquid contact assembly 102 is disposable at a first vessel location in the steam drum 12 and has a vibration component 108 operable to vibrate at natural frequencies which vary as a function of a predetermined characteristic of the liquid at the first vessel location and a support component 110 for supporting the water contact assembly 102 in contact with the liquid at the first vessel location. The signal generator element 130 generates a signal indicative of a natural frequency of the vibration component 108.
