Sono-Vario - Moisture Level Sensor - Brochure

Sono-Vario, a more accurate way to measure moisture. The SONO-VARIO moisture level sensor uses Time Domain Reflectometry to measure the moisture of the material.Because it uses uses Time Domain Reflectometry, the Sono-Vario sensor can measure the  moisture of sand, fine aggregates and other granular materials within 0.1% and coarse aggregates up to 1.25″ (32mm) within 0.2%, which is better accuracy than other microwave methods.  You should position it in a plate where the material flows out of a hopper.  The sensor measures bulk moisture but you can calibrate it to read surface moisture in most materials.
