    Tank Gauge Cistern Tank Level Monitor 

    We have used several cistern gauges in our years of installing rainwater harvesting systems, and, time and again, we find ourselves returning to this little guy -- the Tank Gauge Tank Level Monitor -- when we want a reliable cistern gauge (one that doesn't depend on electricity or batteries for its use).

    This Tank Gauge is a water level indicator that is simple and easy to install.  Suitable for all vented tanks up to 100" in height.  Features an easy-to-read display dial and utilizes a weight float, suspended on a string line to provide accurate readings. Gauge is fitted to the tank via two screws provided.

    Monitoring your rainwater made easy!

    The Tank Gauge is a rainwater tank level indicator which ensures you are able to tell how much water is in your tank at a glance.

    • Quick and easy to install - simple DIY product
    • Seals directly to the tank
    • Suitable for all existing and new tanks
    • No batteries or wiring required
    • Easy to read dial face with 'empty and full' indicators

    1. Uncomplicated and Easy to Install

      This was so easy to install and works great. Need to order a new one, as the level indicator hand fell off after about 9 months of use. For the price and the ease, will gladly order another one. on 9th Sep 2020

    2. Simple, low-tech, but it works

      This is my second gauge--both exactly alike. The first one lasted about 2 years in our so. Texas sun. Easy to install and accurate. on 30th Jul 2020

    3. Great Product

      Flawless functioning.
      Thank you-

    4. Uncomplicated and Easy to Install

      We first ordered a wireless monitor from another company but with our tank shape it was not going to work. Finally found this less expensive and simple solution and so far it's been working great! on 6th Jan 2020

    5. Recently installed, so far no problems

      The product appears adequate in quality. The installation was easy. The ONLY issue I have is probably more my issue, than an issue with the gauge, for most people. I bought this so I would not have to get out of my truck as I drive by my cistern, to tell where the water level is. At a distance, it is difficult to differentiate the black pointer that indicates current level, from the black "hash marks" on the dial. I always carry binoculars in my truck, so I simply use those, my eyesight may be the real "rate limiting step" in this issue. I MAY try and paint the pointer a different color if my binoculars become a hassle. on 2nd Jan 2018

    6. Just bought a second one

      Simple and effective for a quick check on water levels in cisterns. Easy to install, intuitive, nothing to break and little to wear out. Bought another after first one worked so well. Basic and well designed.

    7. Does it's job

      This is the second one I have purchased. I am using it on my underground cistern to monitor the tank level. The first one after about a year the spring inside of it came loose and did not work anymore. Since it is simple and does not need electric, I thought I would have better luck with another one. Only time will tell. on 15th Mar 2017

    8. Works perfect

      I have a concrete cistern under my garage. Now I no longer have to remove the man hole cover . on 26th May 2015

    9. Great Product

      Our cistern level has always been a mystery and since this is our primary way for water for the house it was essential to know how full or empty it truly was. Not being as high-tech or fancy as other tank gauges I was a little skeptical about the product but the price made me say "Eh, it's worth a shot". It has performed flawlessly and the empty and full indicators are VERY easy to adjust according to your specific tank. We no longer have to guess if our water level is low now. WONDERFUL PRODUCT on 28th Jul 2014
