⚠ SJE Rhombus alarms weren't built for fleet operations
Replace Your SJE Rhombus Tank Alerts
With Rivio.
SJE Rhombus makes reliable on-site alarms — but they don't give you fleet visibility, real-time levels, or automated scheduling. Rivio replaces Tank Alert®, Xpert Alert®, and Xpert Alert® WiFi systems with a cellular monitoring platform built for operators managing dozens or hundreds of tanks.
Replace Every SJE Rhombus Alarm Type
No matter which SJE Rhombus alarm you're using, Rivio replaces it with a smarter, cellular-connected alternative.
📶
Xpert Alert® WiFi Indoor Alarm→Rivio Cellular Tank Monitor
Ditch the WiFi dependency. Rivio connects over LTE cellular, works outdoors, and provides continuous level readings — not just alarms.
🔔
Tank Alert® AB / AB Duo→Rivio Smart Alert Monitor
Replace basic audible/visual alarms with a monitor that sends data to the cloud and automates your pump scheduling.
📊
Tank Alert® XT / 4X→Rivio Multi-Input Monitor
Rivio supports multiple sensor inputs with continuous level data, fleet dashboards, and route optimization built in.
📡
Xpert Alert® RF Alarm→Rivio LTE Monitor
The RF alarm sends signals to a nearby receiver. Rivio sends data directly to the cloud over cellular — no base station needed.
SJE Rhombus Alarms vs. Rivio Monitoring

Why Operators Choose Rivio Over SJE Rhombus
📡
Cellular-First Design
Every Rivio monitor connects via built-in LTE. Install at remote sites, rural properties, or anywhere with cell coverage — no WiFi setup.
🖥️
Fleet-Wide Dashboard
See every tank in your fleet on one screen. Filter by fill level, location, or urgency. No more site-by-site alarm checking.
📅
Automated Pump Scheduling
Rivio predicts when each tank needs service based on fill rate data and automatically schedules pump-outs for your team.
📊
Continuous Level Data

🛠️
Built by Operators
Rivio was founded by people who ran tank routes. We built what we wished we had — not another alarm box.

SJE Rhombus Replacement FAQ
Which SJE Rhombus products does Rivio replace?
Rivio replaces the Xpert Alert WiFi, Xpert Alert RF, Tank Alert AB, Tank Alert AB Duo, Tank Alert XT, Tank Alert 4X, and Tank Alert EZ alarm systems for tank monitoring applications.
Is Rivio more expensive than SJE Rhombus alarms?
SJE Rhombus alarms have a lower upfront cost but provide no remote monitoring, no data, and no automation. Rivio's ROI comes from eliminating emergency dispatches, optimizing routes, and preventing overflows.
Can I reuse my existing float switches?
In many cases, yes. Industry-standard float switches — including SJE Rhombus MilliAmpMaster floats — are often compatible with Rivio transmitters. We verify during the assessment.
Does Rivio work at sites with no WiFi or internet?
Yes. That's Rivio's core advantage. Built-in LTE cellular connectivity means your monitors work at remote sites, rural properties, and locations with no internet service.
How many tanks can Rivio manage?
There's no limit. Rivio scales from a handful of residential tanks to enterprise fleets with thousands of monitors across multiple regions — all on one dashboard.
What data does Rivio provide that SJE Rhombus doesn't?
Continuous tank levels, fill rate trends, predicted pump-out dates, historical analytics, compliance reports, route optimization, and automated scheduling — none of which SJE Rhombus alarms provide.
From Alarms to Intelligence
SJE Rhombus alarms tell you something went wrong. Rivio tells you what's happening, what's about to happen, and what to do about it — across your entire fleet.
