I may be getting another. - We took a risk and tried this device which we certainly do not regret. There are many bad review complaining about the guts springing out and after installing this unit, I can understand how this happens. Was easily to install, easy to calibrate, works great for our needs! This is much like setting an old manual clock! What you need to know about the face cover being difficult. The plastic cover is quite right, thin and feels like it may be a bit brittle. It has a small rubber gasket around it just under the outer lip and tiny latching grooves that hold it on well. *What you need to be careful with is don't be too rough and manly when taking the cover off. It can be temperamental but was just fine for us. It was simply to hold up beside the drums and note the position of empty and full from the small black needle that swings back and forth. It was not difficult to carefully move the green (full) and red (empty) hands around either. We installed in the center of a bung plug to make removal, cleaning, replacement or work effortless by simply unscrewing the plug. Works great! Review: Good for rain or potable water barrels. - This works good in my potable well water barrel with a pump to my ice makers which avoids city water usage. Guage is working well but the water is not moving much. No real stress on the float line. ## Features - TANK GAUGE: Always know how much water is in your tank with this easy-to-read, tank-top tank gauge - KNOW YOUR WATER LEVEL: The easy-to-read dial features Empty and Full indicators to reveal at a glance how much water you currently have - EASY TO INSTALL: A single hole in the tank is all that's required for installation, then a simple adjustment of the hands on the dial will calibrate it perfectly for your tank height - SUITS MOST TANKS: The Tank Gauge is suitable for all vented aboveground and below ground tanks up to 8 feet in height - EFFECTIVE WATER MANAGEMENT: Monitor your rainwater collection system efficiently with clear visual indicators that help you track water usage and plan refills accordingly ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004VMFYBI | | Best Sellers Rank | #72,406 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #96 in Rain Gauges | | Brand | Rain Harvesting | | Brand Name | Rain Harvesting | | Customer Reviews | 4.1 out of 5 stars 286 Reviews | | Item Dimensions | 4 x 2 x 4 inches | | Item Highlight | Tank-Top Water Level Monitoring Device, For Rain Water Catching Systems | | Item Weight | 8 ounces | | Item dimensions L x W x H | 4 x 2 x 4 inches | | Manufacturer | Rain Harvesting Pty | | Material | Plastic | | Material Type | Plastic | | Model | TATG02 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | TATGO2 | | Thread Style | Npt | | Unit Count | 1 Count | ## Product Details - **Brand:** Rain Harvesting - **Item Highlight:** Tank-Top Water Level Monitoring Device, For Rain Water Catching Systems - **Item Weight:** 8 ounces - **Item dimensions L x W x H:** 4 x 2 x 4 inches - **Material:** Plastic ## Images ![Rain Harvesting Tank Gauge - Image 1](https://m.media-amazon.com/images/I/71JV+yOzA4L.jpg) ![Rain Harvesting Tank Gauge - Image 2](https://m.media-amazon.com/images/I/81fCoxxhEtL.jpg) ![Rain Harvesting Tank Gauge - Image 3](https://m.media-amazon.com/images/I/81Gdoz6c77L.jpg) ![Rain Harvesting Tank Gauge - Image 4](https://m.media-amazon.com/images/I/71DQQc3jwRL.jpg) ![Rain Harvesting Tank Gauge - Image 5](https://m.media-amazon.com/images/I/81kekBGA6PL.jpg) ## Questions & Answers **Q: Can this be installed on an angle as the roof of my tank is pitched? Thanks.** A: I think it would work just fine. The float that runs the dial is hanging from a string. As long as the angle is not too steep and you position the direction of the gauge so that the string is not too crooked on the spool it should work. It is not that expensive and would be worth a try. It is cheaper to order it directly from the company. **Q: what is the diameter of the float hole needed** A: The hole needs to be 32 mm or ~1.25" min. **Q: How shallow a tank does it work for? Would 2ft work?** A: it could but i use it for a 2500 gallon water tank **Q: What is the diameter of the gauge base and the distance between screw holes?** A: The base of the gauge is 3" in diameter, and the screws are 2 1/8" apart. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than imagined!

Guage is working well but the water is not moving much. No real stress on the float line. ### ⭐⭐⭐⭐ Just what I needed. *by �***� on December 27, 2012* I have an underground cistern; my method of checking has been to lift the heavy cement cover and look down. When my well went dry, and I started hauling water, I went from checking once every few weeks to checking at least twice a week. This thing's a godsend. It's sort of flimsy; the plastic indicators and front piece seem fragile and the slight string to the float is way too thin, in my opinion; I'd feel more comfortable if it were a bit heavier. Still, it was easy to guess where to set the arms, and after about a month of use, I'm very happy with it. When I fill up my cistern, the gauge follows the level perfectly. I have it set on top of the overflow pipe; if it survives the Colorado winter, I'll be pleasantly surprised. For the price (and compared to what meager other offerings I could find online) this gauge is a steal. 2014.08.20 Update - Ordered a replacement for initial one, because the string/twine holding the bobber became frayed. With an old plastic liquor bottle covering the gauge, shows no wear. Knocked off a star for the string. ## Frequently Bought Together - Rain Harvesting Tank Gauge, Tank-Top Water Level Monitoring Device for Rain Water Catching Systems - Leaf Eater Advanced Rain Harvesting RHAD100 Both 3" and 4" Compatible - Rain Harvesting TATS12 Water Tank Screen Filter - Standard - 16 in. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/6583132-rain-harvesting-tank-gauge](https://www.desertcart.be/products/6583132-rain-harvesting-tank-gauge) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-06*
