Corn starch is a final product of the corn wet milling process. It is a commodity product with both consumption and commercial uses. Corn starch is a fine dry powder prone to sticking and caking, making accurate measurement a challenge. Continuous, reliable inventory levels are critical for scheduling timely shipments to end users. Guided wave and non-contacting radar technologies are both suited. Being able to detect build-up enables appropriate maintenance to be scheduled, but non-contacting level measurement technology is particularly suitable for measurement of sticky media prone to build-up.
