  • Description
  • How it works
  • The Farmo Water Tank Level Monitor uses a Hydrostatic pressure sensor to measure the depth of water in real-time and send alerts and data to your phone or dashboard wherever you are in the world.

    Water depth is measured every 15 minutes and edge processing technology will send real time alerts when water levels drop below your trigger point. Periodic reports are sent every 8 hours by default. (NB-IoT version only, LoRaWAN is fixed period reporting only.)

    The device requires a Farmo subscription which covers all data charges, dashboard and alerts. The SIM card, stainless steel bracket and magnet are all included.

    The 7000mAH LiSoCl2 battery will last for over a year before needing to be replaced.

    The choice of options includes NB-IoT (works anywhere you get mobile reception) or LoRaWAN (cheaper annual subscription but needs a gateway). We explain the choice of technologies in detail on the following page: How to choose the right technology for your farm.

    Available with 1.8m or 3.0m cable length.

  • How it works

    A hydrostatic pressure sensor measures the gravitational force of liquid pressure which is converted into depth via the formula P = ρgh where:

        • P is the hydrostatic pressure in Pascals (Pa)
        • ρ (rho) is the density of the fluid in kilograms per cubic meter (kg/m³)
        • g is the acceleration due to gravity, which is approximately 9.81 m/s²
        • h is the depth of the fluid in meters (m)

    A hydrostatic level sensor will accurately measure the depth of the liquid unaffected by the shape of the containing vessel.

    The raw sensor data is depth (m) but most customers prefer to see a percentage measurement. So we apply the formula Depth/Tank Max= Percentage. To use this feature you need to enter the "Tank Max" depth for each tank.
