The silo inventory system based on weight

SiloWeigh tells you the contents of any silo, feed bin, tank or storage vessel as a continuous inventory value. Better than silo level measurement, SiloWeigh measures the actual weight of the vessel and contents to give a true picture of the amount on hand, and it costs less than the best level sensors.
For low cost vessel and silo weight display, you can’t beat the value of SiloWeigh Basic. Designed for farm feed bins and similar applications where a very basic display is adequate. SiloWeigh Basic uses L-Strain sensors with a simple weight indicator to show the current weight of the vessel contents, without all the extra features.
SiloWeigh II Pro pairs the L-Strain sensors with a touch-screen display, to measure silo level by weight. Capacity is 6 vessels displayed as bar-graphs or a trend-graph of each individual vessel. A special display shows weights of past deliveries to detect shortages.
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.

The accurate inventory system for silos, bins, tanks and storage vessels that you can install yourself

SiloWeigh measures silo inventory by weight. The silo software can handle up to 32 vessels.
Identify and stop delivery shortages

SiloWeigh gives you the ability to check every delivery, even weeks ago, against the delivery ticket.  Consequently it puts you in command of the situation.  You can use SiloWeigh II Pro and SiloWeigh.Net silo and bin weighing systems to measure delivery amounts by use of the history recording feature.  It’s not admissible in a court of law but it’s good enough to tackle your supplier or trucker. 2019 article on weather filter and divided silos. Read 2020 article: “How to avoid bursting your silo”. Dec. 2020 article: “Round/square divided, stacked and shared frame silos”.

SiloWeigh is the only system with an advanced weather filter. This eliminates most of the daily variations due to weather, giving you a more accurate and more stable reading as a result. It doesn’t prevent fast performance either. During fills and fast discharge periods it switches to a faster response to minimize delay. Note that the Basic model does not have this feature.

Never run out of material again

The silo software lets you easily see the levels in your silos, tanks or other vessels.  It gives you visual warning at Reorder and Low levels, plus audible warnings if you need them, to prevent loss of production and missed deadlines as a result.

Eliminate the risk of overfilling

You can forget about blown filters and the ensuing environmental hazards.  They are a thing of the past.  Due to SiloWeigh’s High and Overfill alarms, you see immediately when the levels are exceeded and audible warnings alert the truck operator.  You can add a pinch valve also, if you wish to positively prevent an overfill.
L-Strain sensors are temperature compensated. They cancel the effects of the structure’s expansion with temperature while measuring the compression due to load.  Typical accuracy ±1 to 2% of full scale when all four legs are gauged. Skirted silos - expect ±5% of full scale . . . Read more
  • Mount the legs on load cells for higher accuracy (0.1%) (see Applications page).
  • It’s an all-weather system. Sensors, wiring and junction boxes meet NEMA-4, IP66.  You can set up the dust and splashproof industrial touch screen display system in a convenient indoor location.
  • Replace the cable with radio connection when it’s inconvenient, or for long runs of up to 10 miles.
  • It has no moving parts, giving long life and reliability.
  • Safe installation – no need to climb the silo.
“We monitored and found that SiloWeigh works extremely well in all our silos and is the most effective inventory management system.  We have no hesitation in recommending it for anyone wanting a precise inventory figure at any time.” Salman H. Said, Synaxis Readymix, Dubai.

General purpose weight indicator used in CraneWeigh and also in SiloWeigh Basic for silo and bin weighing

For a low cost silo and bin weighing system, you can’t beat the value of SiloWeigh Basic.  Designed for farm feed and grain bins, and similar applications where very basic silo monitoring is adequate, SiloWeigh Basic uses the same L-Strain sensors as our touch screen and Internet-based systems but replaces the advanced silo software with a simple weight indicator.  This shows the current bin or silo inventory without all the extra features.  Note that this indicator does not have the Scale-Tron Weather Filter and as a result the overall accuracy will be poor. Expect errors of 5 to 10% or even more. If you need better accuracy, even for one silo, we recommend either SiloWeigh II Pro or SiloWeigh.Net. The system includes an indoor, NEMA-12 indicator with universal voltage power adapter; its bracket can be bolted to any surface.  Controls include Zero and Tare buttons which can be used to measure fill and discharge values.

SiloWeigh II shows silo level measurement by weight for up to 6 vessels as bar-graphs or trend-graph

For one to six vessels and local display, SiloWeigh II Pro is your ideal choice for silo inventory.  You get a touch-screen display showing up to 6 vessels as bar-graphs or a zoomable trend-graph.  This shows you the previous 14 days of data.  It is packed with extra features such as delivery measurement, hard-wired alarm outputs and our advanced weather filter.  No other manufacturer offers this filter, which keeps your readings steady throughout hot sun and snowstorms while responding instantly to fills and discharges.  Without it, you can get jumps of 20% to 50% and more, lasting several hours.

You will find SiloWeigh II Pro silo level measurement system extremely simple to use, with multi-lingual English, French and Spanish menus.  Other languages are available on request.  You can also use analog liquid pressure (for level) and temperature sensors to extend the usage: liquid tanks, level where the vessel has no legs, temperature for recording curing cycles and moisture when used with the Aqua-range of sensors.  And it handles divided silos, stacked silos or silos on a shared frame.  No other manufacturer can do this.

If you can’t use all six of SiloWeigh II’s display channels, add  liquid tank volume, temperature measurement or moisture measurement.  They all give you a better ROI. Read more in latest update.

No complaints at this point.  The system is working great and has helped us identify some significant gaps between what we should be receiving and what we actually did receive”  Chris Allensworth, Nestle, Jonesboro, NC. Nov 2018
