Are there any good ways to measure the foam level?

Thread Content

Our company produces PVF resin using stainless steel reactors. The raw materials are flammable and explosive liquids. When the reaction takes place, a lot of foam is generated, and the viscosity of the liquid increases. This foam needs to be kept under control; at appropriate times, cold water is used to cool the jacket in order to prevent the foam from increasing. Currently, this process is monitored manually, but in the future we plan to implement a DCS system to eliminate the need for human intervention. So far, we haven’t found any good solution to this problem. The solution I’ve come up with now is to use an image recognition system to monitor the foam level, based on the principle of mimicking the response of human eyes and brain. I was wondering if any of the experts here have any good methods for measuring the level of this foam-containing liquid. . . Thank you! ! This post was last edited by mywlyx on 2009-3-13 17:01]
