Meterra vs. Gallagher water monitoring: an honest comparison
Gallagher has been making farm equipment since 1938 (they invented the electric fence), and their US catalog includes a satellite and cellular tank monitor. Meterra is a water-monitoring specialist. If you're weighing the two, the question isn't whose brand is bigger; it's what the water side of each actually offers. This is our honest take: where Gallagher's heritage, dealer network, and lower yearly fee genuinely win, and where a dedicated water platform pulls ahead on reporting, reach, sensing, and automation.
Two honest starting points
First, respect where it’s due. Gallagher is an 85-plus-year, family-owned company that invented the electric fence, sells in over 100 countries, and backs its US customers with a nationwide dealer network, territory managers, and a repair center in Missouri (per gallagher.com, July 2026). If you’re outfitting a ranch with fencing, weighing, and EID anyway, they are a serious one-stop vendor, and most of this page is about the water monitoring line. One exception gets its own section below: fence monitoring, where the two lineups genuinely cross.
On the US store, that line is now one monitor: the Tank Level Monitor ($399.99, dual satellite and cellular, 2-year warranty), with a posted subscription of $99 a year per device covering both networks. The older satellite-only Satellite Liquid Monitoring System no longer has a US store page, though Gallagher’s product page still uses that name for the line and the store still sells its 26.2 ft sensor cable and mounting plate (all checked September 2026).
Meterra’s entire business is the water side: 4+ years in the field, 2,000+ devices, and a fourteen-product ecosystem of tank, trough, dam, and silo levels on two sensing technologies, flow, rain, weather, soil, fence, and power monitoring, plus cameras and pump & valve controllers. Every device works standalone, and all of them interconnect on one dashboard.

Where Gallagher has the edge
Being fair, here’s what Gallagher genuinely does better today:
- The brand and the dealer network. Eighty-five years, dealers nationwide, territory managers who’ll walk your place, and a US repair center. If you want to buy where you buy your fence chargers and talk to a local human, that’s a real advantage a direct-ship specialist doesn’t match.
- A lower yearly fee. Gallagher posts $99 a year per device, covering both satellite and cellular. Meterra’s plan is $10 a month ($120 a year) after the bundled 3 months. We discount annual plans, but on the posted rates, Gallagher’s recurring fee is lower.
- A longer warranty. Their Tank Level Monitor carries a 2-year warranty to Meterra’s one. We answer with a 60-day money-back guarantee they don’t list, but on pure warranty length, Gallagher wins, plainly.
- One vendor for the whole ranch. Fencing, virtual fencing, weighing, EID, Miraco waterers made in Iowa: if consolidation matters, the water monitor rides along with an ecosystem nobody else has.
- Dual satellite + cellular in one box. The Tank Level Monitor carries both radios on one subscription, which is a tidy design for a property that straddles coverage.
Where Meterra is the stronger choice
- A posted reporting interval. Meterra’s cellular sensors report every hour and alarm the moment a threshold is crossed, and that’s written on every product page. Gallagher’s page describes plans from a quick daily check-in to near-instant alerts without posting a regular interval or saying which plan gets which. If fast alarms matter, ask which plan delivers them and whether the $99 covers it, and get the answer in writing.
- Automation you can order in the US. A Meterra sensor can drive a pump controller or valve controller for auto-fill, dry-run protection, and remote start. Gallagher makes connected pump controllers for overseas markets, but as of July 2026 none are listed on their US store. See water system automation.
- Reach, not just depth. The longest sensor cable on Gallagher’s US store is 26.2 ft, and a cable sensor reads only as far as its cable hangs. Meterra’s Dam Level Monitor is rated to ~330 ft (100 m) of water column and stocks cable in 10, 50, and 165 ft, with any length built to order up to about 330 ft. Length buys more than depth. The cable carries the reading back to dry ground, so the sensor can sit out in the middle of the pond, at the inlet that silts up, or on the side of the dam you can’t drive to, while the communication box stays on the bank. A shallow pond can still need a long cable, and dams, fire reservoirs, and deep storage are beyond a tank cable’s reach entirely.
- Two sensing technologies, more materials. Alongside submerged pressure (which reads true levels under ice), Meterra’s non-contact ultrasonic sensors read any material, including dry feed and grain, which a cable sensor can’t touch. Gallagher’s line covers water, diesel, fertilizer, and liquid feed.
- A water platform, not a water accessory. Levels, flow, rain, weather, soil, power, and cameras on one dashboard, each device standalone but interconnectable. Gallagher’s US water line is one tank monitor.
The fence crossover: where Gallagher meets Meterra twice
Meterra also makes an Electric Fence Monitor, which puts the two companies head-to-head on Gallagher’s home turf, so here’s that comparison played straight.
Gallagher’s US remote fence monitoring is the i Series system: an i Series energizer ($1,499.99–$4,279.99 on their US store, July 2026) plus the $134.99 App Gateway and their free Devices App, with optional $389.99 zone monitors (up to six) reading voltage and current. It’s a deep system. You can even switch the energizer on and off from your phone, which Meterra’s monitor doesn’t do, and the hardware carries a 3-year warranty. (Their pages also reference subscribing to a monitoring service, with no price published as of July 2026.) Two catches, both from their own pages: remote access requires Wi-Fi at the energizer (their suggested fallback is a hotspot; no cellular option is listed on the US store), and it only works with Gallagher i Series energizers. Their any-brand fence tools are handheld testers and a visual pulse indicator, nothing that phones you.
Meterra’s fence monitor is built for the opposite situation: it clips onto the fence you already have, with any brand of energizer, reports hourly voltage history over cellular (no Wi-Fi within miles required), alarms instantly on a voltage drop, runs 3–5 years on its own battery, and shows up in the same app as your tanks, pumps, and rain gauges. Both sides post their prices: Gallagher’s i Series pieces are listed above, and Meterra’s fence monitor is $450, ships to order, and includes 3 months of connectivity, then $10/month.
The clean rule: buying a new high-end energizer anyway, with Wi-Fi in reach? Gallagher’s integrated system is the natural choice. Want fence alerts on your existing setup, off-grid, alongside your water monitoring? That’s what ours is for.
How to decide
- How fast do you need to know? If a daily check-in is fine, both work. If a failure needs to page you now, compare Meterra’s hourly data and instant alarms against the plan Gallagher quotes you, and get that plan’s alert speed and price in writing.
- Will a level ever need to trigger anything? Pump, valve, auto-fill: in the US, that’s Meterra; Gallagher’s US line is monitoring only.
- Count the whole bill. Both bills are posted now. Over three years on one tank, it’s about $629 for Meterra ($299, then $10 a month after the bundled 3 months) and $598 to $697 for Gallagher ($399.99 plus $99 a year, depending on whether the first year is included; ask them). That’s close enough that what the money buys should decide it.
- Buying the rest of the ranch from Gallagher anyway? Their dealer network and one-vendor convenience are honest reasons to lean their way; weigh them against the water-side capability you’d give up.
A note on this comparison
We wrote this because Gallagher’s name carries weight it has earned over 85 years, and anyone comparing tank monitors deserves the water-side facts laid out straight. Everything above about Gallagher comes from their public US information (the water monitor re-checked September 2026, the rest July 2026) and may have changed since, so check with them directly. Meterra is not affiliated with or endorsed by Gallagher; “Gallagher” and “eShepherd” belong to their owners. If you want the same honesty applied to your sites, tell us what you’re monitoring and we’ll give you a straight answer, even if that answer is that the dealer down the road fits you better.
The bigger picture
One pond, one pump, one tank, one storm — zero drives.
Every device below works alone. Linked on one platform, they run the place: the tank calls the pump at the pond, the safety level decides when irrigation is allowed, and the rain gauge overrules everything the moment real rain falls. Watch the rules fire, sped up:
Sped-up example — every level, threshold, and rule shown here is the kind you set yourself in the Meterra app, and each one stays a manual button too. Devices connect over cellular independently, so the pond, the tank, and the sprinklers can be miles apart.

Frequently asked questions
Is Meterra a good alternative to Gallagher's Tank Level Monitor?
For the water side of your operation, that's exactly the comparison to make. Gallagher's US water monitoring is one monitor, the $399.99 Tank Level Monitor with dual satellite and cellular (per their US store, September 2026), inside a catalog built around fencing, weighing, and EID. Meterra is the reverse. Water monitoring is the whole business, with tank, trough, and dam sensors on two sensing technologies, flow, rain, weather, and power monitoring, plus pump and valve controllers, 4+ years in the field, and 2,000+ devices in service. Buying fencing and scales too? Gallagher's one-vendor story is real. Building out the water system itself? That's Meterra's ground.
What's the main difference between Meterra and Gallagher water monitoring?
Focus and reach. Gallagher's current US monitor carries satellite and cellular in one unit, runs a cable sensor into the tank, and costs $99 a year per device for both networks (per their US store, September 2026). Meterra defaults to Verizon NB-IoT cellular with hourly data and instant alarms, adds satellite only where a site needs it, and spans a fourteen-product ecosystem from shallow troughs to 330 ft dams, including controllers that let a sensor run a pump. On speed, Gallagher describes plans from a daily check-in to near-instant alerts and promises alarms within 15 minutes, but doesn't post a regular reporting interval.
Does Gallagher offer remote pump control in the US?
Not on their US store as of July 2026. Gallagher sells wireless pump controllers in some overseas markets, but the US water management catalog lists monitoring hardware, mechanical valves, and waterers only, with no connected pump or valve control. Meterra sells both a pump controller and a valve controller in the US, driven directly by the sensors, so a tank level can start a pump or close a valve on its own. If automation is in your plans, check what's actually orderable in the US before deciding.
Which is cheaper, Meterra or Gallagher?
Close, and on the yearly fee Gallagher is lower, so honesty requires saying so. Gallagher's Tank Level Monitor is $399.99, and its subscription is $99 a year per device, covering satellite and cellular (per their US store, September 2026); the page doesn't say whether the first year is included. A Meterra Tank Level Sensor is $299 with 3 months included, then $10 a month, about $389 in year one and $120 a year after that (we also discount annual plans). Over three years that's about $629 for Meterra and $598 to $697 for Gallagher, depending on whether their first year is included. The bigger difference is what the money buys, one monitor versus an ecosystem with automation.
How often does each system update?
Gallagher's Tank Level Monitor page (September 2026) describes subscription plans ranging from a quick daily check-in to near-instant alerts, and its new-product page promises alarms within 15 minutes when levels change. Neither page posts a regular reporting interval or says which plan includes which speed. Meterra's cellular sensors post hourly data to the app with instant alarms when a threshold is crossed. For a slow-moving storage tank, a daily check-in can be enough; for catching a stuck float or a burst line, ask Gallagher which plan gives you the fast alerts and whether the $99 covers it.
How do the warranties compare?
Gallagher's Tank Level Monitor carries a 2-year warranty (per its US store page, September 2026), longer than Meterra's 1-year, and credit where due. Meterra pairs its 1-year warranty with a 60-day money-back guarantee, so you can run a sensor on your worst tank for two months and return it for a refund of the full product price if it doesn't earn its keep. We didn't find an equivalent money-back guarantee for Gallagher's water monitor on their site (September 2026). Longest coverage goes to Gallagher; lowest-risk trial goes to Meterra.
How does Gallagher's fence monitoring compare with Meterra's Electric Fence Monitor?
They solve different fence problems. Gallagher's i Series system (per their US store, July 2026) monitors voltage and current in up to six zones and can even switch the energizer from your phone, but it works only with Gallagher i Series energizers ($1,499.99–$4,279.99) and requires Wi-Fi at the energizer for remote access. Meterra's Electric Fence Monitor clips to any brand's fence and energizer, reports over cellular with hourly history and instant voltage-drop alerts, and shows up in the same app as your water sensors. Both companies post their prices. Gallagher backs its fence hardware for 3 years; Meterra's Electric Fence Monitor is $450 with 3 months of connectivity included (then $10/month), ships to order, and carries a one-year warranty. Buying a new i Series energizer with Wi-Fi in reach? Theirs. Monitoring the fence you already have, off-grid? Ours.
Are Meterra and Gallagher affiliated?
No. This is an independent comparison written by Meterra, based on Gallagher's publicly available US information (water-monitor facts checked September 2026, the rest July 2026). "Gallagher" and "eShepherd" are trademarks of their owners, used here only for honest comparison. Specs and prices change, so confirm current details with each company before you buy.
