Froth height level sensor

PDF Version Also Available for Download.

Description

A single sensor, comprised of a tube located near the foaming liquid, and another well away from the first, are used to determine the existence of foam in the vicinity of the probe. Two sensors a known distance apart can be used to locate the froth assuming a uniform froth density. The present invention utilizes the pressure differential existing between process chamber ambient pressure and the froth pressure to determine the existence of a froth and its location. Where froth density is not constant, multiple sensors at differing heights with respect to each other, or a single movable sensor, are ... continued below

A single sensor, comprised of a tube located near the foaming liquid, and another well away from the first, are used to determine the existence of foam in the vicinity of the probe. Two sensors a known distance apart can be used to locate the froth assuming a uniform froth density. The present invention utilizes the pressure differential existing between process chamber ambient pressure and the froth pressure to determine the existence of a froth and its location. Where froth density is not constant, multiple sensors at differing heights with respect to each other, or a single movable sensor, are used. Information derived using the multiple or movable sensor yields unambiguous froth density and height data.
