Advice please 4-20 distance measure sensor 8-10 m but not laser

I can't use my favorite IFM laser distance meters for safety reasons. I tried to look for ultrasonic but didn't find models with 8-10 m distance. Please, advise the model or other type of 4-20 sensors that can measure a distance up to 8-10 m. I think even 6 m will be okay as the last chance. It is needed for solid and bulk materials.
