Know every dosing tank's level — across every site.

The tank that has to be there

A dosing or supply tank only earns its keep when the product is in it. Run one dry and the process it feeds misses its dose — a treatment plant falls behind, a line runs on nothing, a customer gets a call. Watch it too conservatively and you burn trips and hours refilling tanks that were still half full. Both failures come from the same root cause: you can’t see the level until you’re standing in front of it, and the tanks are usually the hardest things to get in front of.

Remote level monitoring removes the guesswork. The right sensor on each tank or pond reports the exact level continuously, alarms before it runs low — or climbs too high — and puts every point across every site on one screen. You stop dosing by calendar and start dosing by data.

Two sensing options — matched to the liquid

Meterra measures these tanks and ponds two ways, and the right one depends on the liquid and the vessel:

• Submerged pressure — built for the hard cases. A sealed sensor sits in the tank and reads the depth of liquid above it. It’s engineered for extreme environments — it holds up in aggressive, even acidic media that would wreck an ordinary probe — and because it reads from below, it keeps reporting the true level straight through ice. For most demanding liquids, and for any open pond that freezes, this is the stronger tool. It’s the same technology behind our Dam and Trough sensors.
• Non-contact ultrasonic — the simple, lower-cost option. A unit mounts above the tank and reads the surface without touching anything, so nothing sits in the product. It’s easier to fit and cheaper to run, and it suits enclosed dosing and supply tanks you’d rather keep sealed — which is exactly what Waste Water Innovations chose, below.

In plain terms: for liquids, the pressure sensor is usually the best answer; ultrasonic is the easy, economical one. We match the sensor to your media, your tank, and your climate.

Reading a freeze-prone pond — before it overflows

Open evaporation and waste ponds — common across Utah and the Mountain West — freeze over in winter, which is exactly when the reading matters most. An ultrasonic sensor reads the surface from above, so once the pond ices over it measures the ice, not the water beneath, and can miss a level climbing toward the top. A submerged pressure sensor reads the depth from below the ice and keeps reporting the true level, with a high-level alarm before a lined pond overflows — a spill that turns into a costly cleanup and a reportable environmental incident. For any pond that freezes, that below-the-ice reading is the difference between a warning and a mess.

Case study — Waste Water Innovations

Waste Water Innovations (WWI) supplies the biology that makes treatment plants work better: blends of enzymes and live bacteria that are dosed into wastewater systems so the resident microbes break down waste faster and more naturally. That product lives in bulk tanks at the sites it serves — and a tank that runs dry means a plant misses its dose.

Troy at WWI used to manage those tanks the only way he could: by driving to them. His six active tanks are spread across Hawaii, Idaho, Montana, Utah, and Colorado, so every one was a trip, and every refill was a guess based on expected run-time. The guess was usually wrong in one of two costly directions — he’d arrive to find a tank already empty, meaning the plant had been short on product, or still holding weeks of solution, meaning a long trip for nothing.

He fit each tank with a Meterra ultrasonic Tank Level Sensor — the non-contact, lower-cost option that suited his sealed tanks, reading the level from above with nothing to fit inside the vessel. Now Troy sees the exact level of all six tanks — depth, volume, and percentage — from his phone, and refills on real data instead of a calendar. The wasted drives are gone, and so are the surprise empties: each tank gets topped up when it actually needs it, not before and not too late.

What Meterra monitors

• Dosing and metering tanks — bioaugmentation product, polymer, coagulant, and treatment chemical feeding a process, watched so the feed never runs dry.
• Bulk chemical and supply tanks — the drums, verticals, and yard tanks you reorder against, tracked on data instead of a dipstick; a pressure sensor for the aggressive stuff, ultrasonic for the rest.
• Evaporation and waste ponds — open ponds and lagoons, watched with a submerged pressure sensor that reads beneath ice and alarms before an overflow.
• IBC totes and portable tanks — the same sensor works on a tote you move between sites.
• Multi-site networks — dosing or supply points spread across a region, all reporting to one dashboard grouped by location.

The whole network on one screen

The advantage compounds the moment you have more than one tank. Every sensor reports into one account, so a tank in Hawaii and a tank in Colorado sit side by side on the same dashboard — live level, volume, percentage, and the drawdown trend that tells you when each one will need a refill. Set a low-level alarm per tank and the network tells you where to go next, instead of you driving to find out. Every reading exports to CSV for your records.

Built for a remote site

There’s rarely power or a network where these tanks sit. Meterra doesn’t need either: the sensor runs on battery or solar, installs in about 15 minutes with no wiring or electrician, and reports over Verizon NB-IoT cellular — with satellite for sites that have no cell coverage at all. Confirm coverage at the location and it’s monitoring from the day it’s mounted.

A note on scope

Meterra monitors the level in the tank — depth, volume, percentage, trend, and alarms. It doesn’t dose, meter, or certify the product, and it doesn’t replace your process controls or required testing. What it does is make sure you always know how much you have and when to refill, so the equipment and people downstream of that tank never get surprised.

Getting started

Start with the tank that’s cost you the most — the one that ran dry, or the one on the longest drive. Tell us how many dosing or supply points you run and where they sit, and we’ll confirm coverage and map a setup that puts every tank on one screen.
