Installation Instructions

For Sealed Tanks (Drilling Required)

  1. Drill a 20mm hole into the top of the water tank lid, ensuring that the lid is open to avoid debris going into the tank
  2. If there is no water tank lid, inspection hatch, or any access to the internal of the tank, a 32mm hole can be drilled and the transducer lowered into the tank through the hole
  3. Pull the transducer cable plug back through the hole, with the stainless-steel transducer in the tank, and secure the grommet around the cable. Place rubber grommet into the hole to seal. The grommet suits both 20mm and 32mm holes
  4. Secure the plug into the Tank Level Pro, ensuring that the location tab and pins are aligned on the plug and socket
  5. Tighten the securing screw on to the socket
  6. Open the battery compartment and remove the insulation tabs to connect the battery
  7. Secure the Tank Level Pro on the outside of the water tank with inbuilt magnets or the Velcro
  8. Download the App from the iOS or Android Play Store, searching for tanklvlpro
  9. App setup is simple, but further instructions can be found by following the QR Code below

For Corrugated Tanks (No Drilling Required)

  1. Place stainless steel transducer into tank and thread plug through the corrugation in the tank roof. In some instances, the transducer plug may not fit through the corrugations, and a screw may have to be loosened, this can be re-tightened once the plug is through
  2. Follow steps 4 to 9 for Sealed Tanks

    Love love love! Awesome product! No more climbing ladders or trying to get the level by tapping the side of the tank, we can just sit inside and check the level on our phone.

    Love the product…..the water level sensors really were easy to install, would have given 5*, but one of the products did not reach down to the bottom of the bore hole. It was returned with no questions asked!!!

    This device takes the stress of “how much water do we have left?” away. After researching tank monitoring devices for about 6 months and discovering many have limitations around number of tanks, size or shape of tanks or just don’t do underground tanks I found this product. It handles any type of tank as long as you know Height and Volume, it’s also easy to install even for the not so handy. The app is easy to read and not clogged with statistics you just don’t need. I will be buying more to monitor all my different sized and shaped tanks.
