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.

L-Strain, advanced silo weight sensor
Gives accurate measurement on silo leg or skirt with little change as the structure heats and cools. A stress sensing section measures the compression due to weight and a compensating section corrects the errors due to thermal expansion in the structure.
Silo Weight Sensor can be applied to steel, aluminum and stainless structures . . . Read more
Typical accuracy ±1 to 2% of full scale when all four legs are gauged.
Mount with bolts through holes drilled in the leg on its neutral axis, where you do not weaken the structure with these holes.
On round legs, weld flat surfaced tabs in place as sensor mountings.
All-weather. Sensors, wiring and junction boxes meet NEMA-4, IP66.
Connect by cables and junction boxes to the DJB (digital junction box).
Single digital cable from all silos to an indoor location up to 1 km (3000 ft) away.
Radio connection when it is difficult to run cable.

Liquid level sensor
Allows you to use SiloWeigh on tanks. The combination of a pressure sensor and SiloWeigh indicator can show either the level in the tank or the volume in gallons, liters etc. It is important that the tank is symmetrical in the vertical direction. As a result, accuracy is excellent.
Attach to a T-adapter in the main or spare outlet . . . Read more
Submersible version is available when T-adapter cannot be used.
High accuracy, typically 1/2 to 1%.
The expansion of the liquid with temperature does not affect the reading.
Additional equipment necessary for petrochemicals and other combustible liquids.
Up to four sensors to one DJB for SiloWeigh.Net.
Up to two sensors with SiloWeigh II Pro at no extra cost.
Low-cost addition to SiloWeigh II or SiloWeigh.Net, easy to justify.
To give the ultimate in accuracy, use load cells, the ultimate weight sensors, under the silo or vessel. Shown here is a shear beam load cell assembly supporting the leg of an agricultural type silo.
When accuracy is more important than minimizing cost . . . Read more
Typical accuracy ±0.02 to 0.1% of reading when all legs are mounted on load cells.
Load cell mounts are available up to several hundred tons per leg.
You need to lift the vessel in most cases, in order to fit these load cell mounts.
Alternatively, you can stabilize the silo while cutting the leg to fit a new bottom plate and the load cell mount.
Connect up to 8 load cells to the DJB’s four inputs.

Temperature recording
Connect our TempTron temperature probe and start recording temperature of your mix. Add it to your batch reports to gain insight into concrete curing problems, or just monitor the temperature of your product inside your silos. Adding temperature to SiloWeigh II or SiloWeigh.Net is easy, costs very little extra and improves your ROI. Or anything else that needs recording and has an analog sensor.
Weldable gauges
For special applications, use the original SiloWeigh silo weight sensor when bolt-on sensors cannot be used. Examples are where there is lack of room or other physical limitations.
These sensors require surface preparation for their application . . . Read more
Accuracy slightly better than the L-Strain sensors, depending on the application.
Requires special care, good eyesight and a steady hand during welding.
Two levels of waterproofing – silicone gauge covering plus outer plastic shell.
