Wireless tank monitoring. Know every level from your phone.

One wireless sensor for every tank on the place

You know the routine. You drive out to check a tank, it’s fine, and the morning is gone. Or you skip the drive, and that’s the week a line lets go and the tank you were counting on runs dry. The Meterra Tank Level Sensor ends that trade for $299, three months of connectivity included. It sits on top of the tank, reads the surface with ultrasonic sensing, and sends the level to your phone every hour. The moment a tank runs low or a leak starts pulling it down, your phone knows before your boots do.

It’s built for the way ranches and farms actually work. No power at the tank? It runs for years on its own battery. No Wi-Fi for miles? It connects itself over the cellular network and starts reporting on its own. And because it simply measures the distance to a surface, one unit reads water, diesel, liquid fertilizer, even dry materials like grain and feed. One sensor covers nearly everything you store. That is exactly how wireless tank monitoring should be built, and after more than four years in the field with 2,000+ devices in service, we’ve had the time to get it right.

It earns its keep well past the fence line, too. The same sensor watches bulk chemical and dosing tanks at treatment and industrial sites, where you want the vessel sealed, the cost down, and operators refilling on a reading instead of a drive-by. One honest limit: for harsh, acidic, or freeze-prone liquids, our submerged pressure sensor is usually the better tool, and we’ll steer you to it. Here’s what both technologies look like in hand, on a real job:

And the reading can do more than sit on your phone. Pair the sensor with a pump controller and the tank runs its own refills: pump on at 40%, off at 95%, with no control wiring between them. That’s the heart of water system automation, and it’s how systems whose buried float-switch wiring has failed get their automation back.

What it fits, and what it doesn’t

The honest version, so you can rule it in or out before you spend anything.

It fits a tank with a top opening and a clear path down to the surface: poly, steel, or concrete, upright or squat, one tank or fifteen. The measuring range runs from roughly 10 inches out to 23 feet, which is the distance from the sensor down to the surface it has to read. That covers the great majority of farm, yard, and supply tanks, IBC totes, cisterns, and rainwater storage. Because it measures a distance rather than dipping into anything, the same unit reads water, diesel, liquid fertilizer, bulk chemical, and dry material like grain or feed.

It does not fit four situations, and we would rather say so here than after you have paid:

• Deeper than about 23 feet from the sensor to the surface. Past that the reading is out of range and the job wants submerged pressure sensing, which is built to a cable length that matches the site. The ultrasonic vs. pressure guide covers the trade, and we scope the length with you.
• No top access, or something in the way. The sensor needs a mounting point above the liquid and an unobstructed path to the surface. A fill pipe, a baffle, or a ladder in the beam’s way is a problem to solve before install, not after.
• A tank that freezes over. Once a lid of ice forms, an above-water sensor reads the ice, because the ice is now the surface. On a stock tank the answer is a tank heater; on open water that ices over, the answer is the submerged sensor that keeps reading beneath it.
• Harsh, acidic, or freeze-prone liquids. Our submerged pressure sensor is usually the better tool, and we will steer you to it rather than sell you this one.

If you are not sure which side of that line your tank falls on, send the dimensions and a photo and we will tell you. We would rather lose the order than sell the wrong sensor.

What it replaces

Most tanks already have some way of telling you what is in them. Here is what each one actually gives you, and what changes when the reading goes wireless.

• A stick, or climbing up to look. Accurate enough, and free, but it only reports when you are standing there. You get one reading a day at best, and none at all on the days you did not make the drive.
• A sight gauge on the side. Same limitation as the stick, plus it has to be read in person and it tends to cloud, foul, or freeze. A wireless tank gauge gives you the same number hourly from wherever you are, along with the direction it is moving.
• A float switch. A float tells you the level crossed a point. It does not tell you the level, the trend, or how fast it got there, and floats stick. That last part is the single most common failure we hear about, which is why we wrote a guide on what a stuck float valve looks like.
• A hardwired level transmitter. These are accurate and they feed a control system properly, but they need a signal run and usually a power run back to a panel, which is a trench and an electrician. A wireless level transmitter skips both: the sensor runs on its own battery for 3+ years and reports over cellular, so the cost of adding the fifteenth tank is the same as the first. Where an existing control system does need the reading in its own language, that is a 4-20 mA or Modbus bridge rather than a trench.

The pattern in all four: the old methods tell you a level when you go and ask. This one tells you when something changed, which is the only version that helps at 2 a.m. or on the far side of the property.

The whole bill, in writing

$299 buys the sensor with three months of connectivity in the box; after that, plans start at $10/month per device. That is the entire cost, posted right here, backed by a 60-day money-back guarantee and a one-year warranty, and shipped from US stock within 1-2 business days. If you’re comparing vendors, get every total in writing before you spend a dollar. A vendor who’s proud of the total posts it, and ours is posted. If another column genuinely comes back better for your tanks, buy it. We’re comfortable saying that next to our price.

Or see it on real systems first: the customer installs page shows this sensor on an Arkansas stock tank and on dosing totes across five states.
