Meterra vs. Trough D Tech: an honest comparison

Two companies that post their prices

Most of this market hides its pricing behind a quote form. SensorTech does not, and neither do we, which makes this the rare comparison you can actually check line by line instead of taking somebody’s word for it. Credit where it is due: they put the number on the page.

Everything below about SensorTech comes from their own site, read on 22 August 2026. Prices change, so check theirs before you decide.

What Trough D Tech is

SensorTech, LLC is based in Kansas and sells a consumer-facing D Tech line alongside a longer-standing industrial tank monitoring range called Level Devil. Trough D Tech is the livestock water product in that line.

From their product page: a submersible hydrostatic pressure sensor, monitoring water troughs, stock tanks, and water well tank configurations, with notifications by mobile-friendly web, text, and email when water is low. Made in the USA. Listed at $349.99, with a required $72 annual cellular data plan, and a carrier choice at checkout of Verizon or AT&T/T-Mobile.

That is the same sensing technology Meterra uses on a trough. Not a similar one. The same one: a sealed sensor sitting in the water reading the depth of the column above it.

The price, both ways, over five years

Both companies post enough to do the arithmetic, so here it is on one trough.

	Trough D Tech	Meterra Trough Level Monitor
Hardware	$349.99	$399
Connectivity	$72/year, required	3 months included, then from $10/month
Year one	$421.99	$489.00
Five-year total	$709.99	$969.00

Theirs is cheaper, by about $259 over five years on a single trough. Buying three troughs does not flip it, and neither does buying ten, because the gap scales with the count. If your decision is purely the cost of watching one trough, the honest answer is that SensorTech will do it for less money, and you should weigh that seriously.

Meterra’s annual plans are discounted below the $10/month figure used above, which narrows the gap without closing it. We have used the posted monthly rate rather than a number we have not published.

Where SensorTech genuinely wins

• Price. Said once above, and it does not become less true further down a page.
• Carrier choice. Verizon or AT&T/T-Mobile, picked at checkout. Meterra runs on Verizon NB-IoT. If Verizon does not reach your watering point and AT&T does, that decides it, and nothing else on this page matters.
• A cheap, replaceable battery. Their store lists a D Tech replacement battery at $10.99, which is a sensible way to build a field device.
• Made in the USA, stated on their product pages.

Where the difference actually shows up

What happens if it does not work out

This is the one we would want to know first as a buyer.

Meterra sensors carry a 60-day money-back guarantee alongside a one-year warranty. Put one on the watering point that has caused you the most trouble, run it for two months, and if it has not earned the next sensor, send it back for a full refund.

SensorTech’s published refund policy warrants their products against defects in material and workmanship for 12 months. On refunds it is explicit, in their words: “At no time will SensorTech, L.L.C. refund monies paid for equipment or services.” (Refund policy, read 22 August 2026.)

Both are legitimate. A no-refunds policy is common in agricultural hardware and it is not a mark against the product. But it does mean the $421.99 is spent the moment you activate it, and ours is not. On a device you have never held, that difference is worth real money.

When the water is not all troughs

Most places we work on do not have one kind of water. There is a supply tank at the yard, a few troughs down the run, and a dam or a pond somewhere out the back. Those want different sensors, and this is where the two catalogues diverge.

A trough and a dam both want something in the water reading depth. A clean supply tank usually does not: put a probe in it and you have introduced something to foul, corrode, and pull out for cleaning, in the water you actually use. Meterra’s answer is the $299 Tank Level Sensor, non-contact ultrasonic, reading the surface from above with nothing submerged at all, alongside the submerged pressure sensors for troughs and dams. Three sensors matched to three jobs, one account, one app, one bill.

SensorTech’s D Tech trough product uses submerged pressure sensing, and their product page lists stock tanks and well tank configurations among its uses. Their separate Level Devil range covers single and multi-tank installations with a wider set of sensing and connectivity options, including satellite and Ethernet, and relay outputs that can drive pumps and alarms. It is a capable range. It is also a different product family from the $349.99 trough monitor, so if you are pricing a mixed property, price the family you would actually end up buying rather than assuming the D Tech number carries across.

Sites with no signal at all

Carrier choice solves a marginal-coverage problem. It does not solve a no-coverage problem. For watering points with no usable cell signal from anybody, Meterra offers low-orbit satellite, at more cost and with less consistent coverage than cellular. We confirm coverage at your specific points before anything ships, and we would rather tell you a site will not work than sell you a sensor that cannot phone home.

So which one should you buy

Buy Trough D Tech if you are watching troughs and stock tanks, the count is not going to grow into other kinds of water, your service is AT&T or T-Mobile rather than Verizon, and the lowest five-year number is what decides it. On those terms it is the better buy and we are not going to pretend otherwise.

Buy Meterra if you want to try one before committing to a fleet, if your water comes in more than one shape and you would rather have the right sensor on each than one sensor stretched across all of them, if you want nothing submerged in a supply tank you drink from, or if a watering point has no cell coverage and needs satellite.

We have been in the field over four years with more than 2,000 devices in service, and the fastest way to find out which of those two paragraphs is yours is to put one sensor on your worst watering point. Ours comes back for a refund if it does not convince you. That is the whole argument, and it is the reason we are comfortable printing their price next to ours.
