| description | A separation column and method for separating anion and cation exchange resins in an upwardly flowing stream of water employing ultrasonic level sensing means. The sensing means include first and second transducer means for respectively sensing and receiving an ultrasonic signal in the frequency range of 1 to 5 megacycles per second. In one embodiment of the invention, the level of resin within the column is sensed when the resin interrupts transmission of the ultrasonic signal at a probe. In a second embodiment, the ultrasonic signal is directed toward the surface of the resin, and the time delay for receipt of an echo is measured. This time delay, in turn, gives an indication of the level of ion exchange resin within the column. |
