⚠ Still walking to a wall-mounted LED display to check tank levels?
Replace the SJE Level Monitor™ CL
with Remote Monitoring.
The SJE Rhombus Level Monitor™ CL shows tank levels on a local LED bargraph — but you have to be standing right in front of it. Rivio sends real-time tank levels to your phone, tablet, or computer over built-in cellular (LTE) so you can monitor every tank from anywhere.
🚨
The Level Monitor CL is a local-only device — no remote access, no alerts to your phone, no cloud data. Rivio gives you all of that over cellular.
What Is the SJE Level Monitor™ CL?
The Level Monitor™ CL is a wall-mounted indoor display that uses SJE's C-Level™ floatless sensor to show tank level on a 10-segment LED bargraph. It includes an adjustable local alarm — but has no remote connectivity of any kind.
🔋
Local Display Only
Tank level is shown on a 10-segment LED bargraph mounted on a wall. You have to physically walk to the display to check levels — no phone, no app, no remote access.
🏠
Indoor Only (NEMA 1)
Rated for indoor use only. Cannot be installed outdoors at the tank site. The display must be mounted inside a building near a 120V outlet.
🔇
No Remote Alerts
The alarm is an audible buzzer and light on the unit itself. No text messages, no email alerts, no push notifications — if you're not there, you won't know.
📏
Limited Tank Depth Range
The C-Level™ CL40 sensor covers tanks 12″–40″ deep. The CL100 covers 25″–100″. Deeper tanks or non-standard configurations aren't supported.

Why Operators Upgrade from the Level Monitor CL
📱
Check Levels from Anywhere
See real-time tank levels on your phone, tablet, or computer — no more driving to the site just to read an LED display.
🔔
Get Alerts Before Problems
Rivio sends text and email alerts when tanks reach thresholds you set. The Level Monitor CL only buzzes locally — if nobody's there, nobody knows.
📈
Fill Rate Trends & History
Track how fast tanks fill over days, weeks, and months. Predict pump-outs instead of reacting to alarms.
🖥️
Manage Every Tank in One Dashboard
See all your tanks fleet-wide in a single view. The Level Monitor CL shows one tank at a time on one wall-mounted display.
🌧️
Works Outdoors & Off-Grid
Rivio monitors install at the tank — indoors or outdoors. No 120V outlet required at the display location, no NEMA 1 indoor limitation.
📅
Automated Pump Scheduling
Rivio uses fill rate data to automatically schedule pump-outs, eliminating guesswork and unnecessary truck rolls.
How the Upgrade Works
01
Tell Us About Your Tanks
Share your tank count, depths, and locations. We'll recommend the right Rivio sensor for each site — no matter how remote.
02
Install at the Tank
Pre-configured Rivio monitors arrive ready to mount at the tank. Power on and they connect automatically via cellular — no WiFi, no wiring back to a building.
03
Monitor from Anywhere
Your cloud dashboard shows real-time levels, fill trends, and alert history for every tank. Set custom thresholds and let Rivio handle the rest.
Level Monitor CL Replacement FAQ
Can Rivio replace the SJE Level Monitor CL?
Yes. Rivio replaces the Level Monitor CL with a fully remote system. Instead of an LED display on a wall, you see tank levels on your phone or computer from anywhere — plus alerts, trend data, and automated scheduling.
Does Rivio use a C-Level™ sensor like the Level Monitor CL?
Rivio uses its own sensor technology that handles a wider range of tank depths and types. Unlike the C-Level™ sensor, Rivio's sensors transmit data over built-in LTE cellular — no cables running back to a wall display.
Can I still see tank levels on-site?
Yes. While the Level Monitor CL shows levels on a local LED bargraph, Rivio lets you pull up real-time levels on your phone from the tank site or from 1,000 miles away.
Do I need 120V power like the Level Monitor CL?
Rivio monitors are designed for flexible installation. They don't require a 120V outlet at a wall-mounted display location. Talk to us about power options for your specific site.
What tank depths can Rivio monitor?
The Level Monitor CL is limited to 40″ or 100″ depending on the C-Level™ sensor model. Rivio monitors handle a much wider range of tank sizes and depths — contact us for your specific requirements.
How is Rivio different from just adding WiFi to the Level Monitor CL?
The Level Monitor CL has no connectivity at all — it's a standalone display. Rivio uses built-in LTE cellular, so it works at remote sites with no WiFi, no internet, and no router. You get a full cloud dashboard, not just a local LED bargraph.
Stop Walking to a Wall Display
Upgrade from the SJE Rhombus Level Monitor™ CL to Rivio and check every tank from your phone. Real-time levels, smart alerts, fill-rate trends, and automated scheduling — powered by cellular, not a wall-mounted LED.
