Styrofoam extrusion-Thickness and Density Measuring Device

Hi all,

Im currently working on a project that requires me to continuously measure the density and thickness of a sheet during an extrusion Styrofoam process.

I have researched sensors and have found some that will do the job but of course they are in the $10k range. These however only measure the thickness. I cant seem to find some that measure the density. I have no experience in this field. Does anyone know of a company that makes a density measuring device that would work for this?

Thanks

Would an ultrasound device work?
