How SiloSpi Silo Level Sensor Works

SiloSpi is installed at the top of the silo, where it continuously measures material levels using patented sensing technology. When dust accumulates, the sensor automatically cleans itself to maintain accurate readings. Inventory data is securely transmitted to the cloud, allowing users to monitor silo levels, receive alerts, and make informed inventory decisions from any connected device.

Frequently Asked Questions

SiloSpi silo level sensor uses a time-of-flight laser sensor to determine the distance between itself and the top of the silo contents. Using calibration data obtained over 2 empty/fill cycles, it is then able to work out the tonnage of the contents of the silo.

No. The units send data over the sigfox, cellular or lora networks, meaning there is no top up of sims or Wi-Fi connection needed.

The unit is +/- 3% accurate  on silos up to 40m tall.

The minimal calibration time is two cycles of filling and emptying the silo. This allows us to get a variety of levels to use as calibration points. The more points we get the more accurate the levels will be.

There are 3 options for power – mains, battery and solar.

The lens is cleaned using our patented air jet system. The air supply in mills usually comes from existing compressed air sources and on farms it can be introduced manually by the user via a pump connected to the bottom of the silo.

Yes. There is a subscription to cover the connectivity and maintenance of the system. The amount depends on the application and the frequency of which we monitor the silo. Contact us for more information.

Yes. We can configure your silo monitor to send you a text or an email at a low level point that you choose, which you can change at any time if you wish by contacting Lvlogics support team. We can also include other people in the notification set up to assist with automatic reordering of silo contents.

We send you a link to a web app. This opens up the gauge page on your phone. You can save that link as an icon on your home page so that you will easily be able to access your data at any time.
