Trough Level Monitor: what it is and how it mounts

A sealed pressure sensor sits in the trough on a heavy-duty cable, and a small box with an internal antenna mounts on the trough or the nearest post. It reports the water level every hour and alarms when a trough runs low or empty. Built to live around livestock.

What it includes

The trough level monitor: a white communications box with the pressure sensor on a grey conduit-covered cable

  • Pressure transducer sensor on the end of the cable. It reads the depth of water above it, so it works in any trough shape and keeps reading under a skin of ice.
  • Heavy-duty conduit over the cable, so stock rubbing on it or stepping near it does not wear it through.
  • Internal antenna, with nothing sticking out for an animal to snap off.
  • Level alarms to your phone, and multiple users on the same account.

Where it mounts

Trough monitor box screwed to the edge of a concrete trough with the sensor cable running into the water
On the trough itself: box on the rim, sensor in the water.

On a fence post beside the trough, with the conduit running down into it.

Mount the box on the trough rim or on the nearest post, high enough to stay out of the mud, and run the conduit so the sensor rests on the floor of the trough. The 9 ft cable reaches from a post to the floor of a standard trough with slack to spare.

Activate it

  1. Open the first box and hold the button down for 5 seconds, or until the light flashes rapidly.
  2. The device boots for a minute or two, then connects to the cellular network and sends its first reading. That first reading can take up to 10 minutes to appear in the app.
  3. Open the device in the app, tap the pencil icon, and enter the trough’s depth so the reading shows as a level.
  4. Add a low-level alarm the same way as on the other level sensors: pencil icon, alarm bell tab, below a level %, save. See the alarm steps in the tank sensor guide.
