Feed bin level sensor for poultry farms

Henlytics puts a radar level sensor on the roof of each feed bin and shows how full every silo on the farm is on your phone, with an alert when a bin drops below the level you set. Nobody climbs a ladder or knocks on the side of a bin to guess what is left.

  • 76 to 81 GHz radar, no contact with the feed
  • Alert at the level you choose
  • Every bin on one screen
Two radar level sensors, one with a threaded mount and one with a flange mount

An empty bin is a feed order placed too late

Feed deliveries are booked days ahead. The level that matters is the one you see before the truck needs to be called.

Birds off feed for a few hours set the whole house back

When a bin empties overnight, the feed lines run dry and every bird in the house goes without until someone notices in the morning.

A low-level alert on the phone turns that into a delivery call made in daylight, with feed still in the bin.

Knocking on a bin is a guess, and climbing one is a risk

Feed bridges and cones hang up, so the sound on the outside of the bin or a look through the hatch often says more feed is left than there is.

A radar on the roof measures the distance to the feed surface from above, on every reading, without anyone going up a ladder.

A farm with several houses needs one picture of its feed

Seeing every bin side by side is what lets the farm order one full truck instead of topping up whichever bin someone checked last.

The same screen shows the air quality and fan status of each house, so feed is not a separate system to open.

How a bin gets onto your phone

  1. A radar on the bin roof

    The sensor mounts on the roof of the bin and points down at the feed. It does not touch the feed and has no moving parts inside the bin.

  2. Wired to the house controller

    It connects to the Genesis controller of the nearest house, the same controller that reads the air quality sensors, and reports over the cellular network.

  3. A level you choose

    Set the alert level for each bin to match how long a delivery takes to arrive, so the alert comes while there is still time to order.

The radar level sensor

An industrial radar built for powders and solids as well as liquids, so dust inside a feed bin does not blind it.

Questions farmers ask

Does a radar level sensor work in a dusty feed bin?

Yes. The RLM-120 is a high-frequency radar made for solids and powders as well as liquids, and dust in the air of the bin does not stop the measurement the way it can with ultrasonic sensors.

Where is the sensor mounted on the bin?

On the roof of the bin, pointing down at the feed, away from the fill pipe so the stream of feed during a delivery does not cross the beam.

What does the app show for each bin?

The level of each bin as measured by the radar, with its history, so you can see how fast each bin is emptying. You set the level at which an alert goes to the phone.

Can one controller read the bins and the house sensors?

Yes. The radar connects to the Genesis controller of the house it feeds, alongside the ammonia, CO2 and climate sensors, so a bin does not need a controller of its own.
