SiloWeigh.Net silo inventory system

SiloWeigh.Net pairs the L-Strain sensors with a computer-based display. Its capacity is 32 silos displayed as bar-graphs or a trend-graph of each individual silo.  Any computer on the local network can view the silo/tank/bin inventory using a web browser.  A cloud-based database displays all the company’s vessels through the Internet.
