SILOWEIGH.NETSPECIFICATIONSENSORSSENSOR SPECINSTALLATIONFAQsVIDEO/BROCHURE
SiloWeigh.Net pairs the L-Strain sensors with a computer-based display, giving capacity for 32 silos displayed as bar-graphs or a trend-graph of each individual silo.  Any computer on the local network can view the silo or tank inventory using a web browser and a cloud-based database displays all the company’s vessels through the Internet.
Most silos on legs and skirted silos use the L-Strain silo weight sensor. However, SiloWeigh can use pressure sensors to measure liquid level, load cells for high accuracy and weldable gauges for special applications.SiloWeigh II can also use any 4-20 mA analog sensor, allowing you to gain more value by recording temperature or moisture values.
The L-Strain silo weight sensor compensates for the expansion of the underlying metal, making it extremely stable on steel legs and skirts as well as being applicable to aluminum and stainless steel silos.
SiloWeigh vessel inventory systems are self-install kits. You can do it yourself from scratch, and we provide the critical tools. Read on and see how simple it really is, or ask for our installation training presentation. If you wish, we can do it all for you; just call us.
Can SiloWeigh be installed on any type of silo leg? Is there any limit to the silo size or capacity? Will it wear out in a few years? How easy is SiloWeigh to install? This page answers these questions and others.
