Rochester Sensors TEK 811 LR
+ Rivio Fleet Dashboard.
The TEK 811 LR is the long-range variant of Rochester Sensors' cellular LTE ultrasonic sensor — built for taller tanks and large liquid vessels. Pair it with Rivio to stream those readings to a live cloud dashboard, with GPS tracking and automated job reports for every asset in your operation.
What Is the TEK 811 LR?
The TEK 811 LR is Rochester Sensors' long-range cellular ultrasonic level sensor — sharing the same LTE CAT-M1/NB-IoT/2G platform and UL 121201 C1D2 certification as the standard TEK 811, but with an extended measurement range for taller vessels.
📏
Extended Measurement Range
The LR variant is designed for deeper or taller tanks where the standard TEK 811 range isn't sufficient. Ideal for large storage vessels, bulk tankers, and industrial holding tanks.
📡
Same LTE Cellular Platform
Like the TEK 811, the LR model transmits over LTE CAT-M1, NB-IoT, and 2G fallback — no additional modem or wiring required for data transmission.
🏷️
UL 121201 C1D2 Certified
Rated for Class I Division 2 hazardous locations — suitable for fuel, chemical, and industrial liquid environments where flammable vapors may be present.
🔊
Non-Contact Ultrasonic
Measures level without touching the liquid. No float, no probe, no corrosion — reliable performance across chemical, food-grade, and wastewater applications.
How TEK 811 LR + Rivio Works Together
The TEK 811 LR handles the sensor layer. Rivio adds the dashboard, GPS, job detection, alerts, and reporting layer on top.
01
LR Sensor Reads Deep Tanks
The TEK 811 LR measures level in tall or large-capacity vessels and transmits readings over LTE — no cabling back to a control panel needed.
02
Rivio Processes & Classifies
Rivio adds GPS context, detects job state transitions (pumping, loaded, discharge), and logs every event with timestamp and location.
03
Full Fleet View from Any Device
Your team sees all assets — trucks and fixed tanks — on a live map with real-time fill levels, job states, and alerts.

Who Uses TEK 811 LR + Rivio
🏭
Large Holding Tank Operators
Monitor bulk storage and holding tanks at remote sites without on-site staff. Get alerts when levels hit thresholds.
⚗️
Chemical & Industrial Facilities
Track chemical storage vessels in C1D2 environments with non-contact ultrasonic measurement and real-time alerts.
🚛
Liquid Hauling Fleets
Tanker trucks with tall or large-capacity tanks benefit from the LR range. Dispatch sees fill level and GPS on the same dashboard.
💧
Wastewater & Septic Systems
Deep septic tanks and collection sumps benefit from the LR range. Monitor levels remotely and dispatch only when tanks are near full.
🥛
Food & Beverage Processing
Track dairy, sweetener, or cooking oil storage tanks. Non-contact measurement keeps sensors clean and calibration minimal.
⛽
Fuel & Energy Storage
C1D2 certification covers fuel storage environments. Monitor bulk fuel tanks at depots or remote generator sites.
TEK 811 LR + Rivio FAQ
What is the difference between the TEK 811 and TEK 811 LR?
The TEK 811 LR extends the ultrasonic measurement range for taller or larger vessels. Both use the same LTE CAT-M1/NB-IoT/2G platform and C1D2 certification. Rivio integrates with both.
Can Rivio monitor fixed holding tanks, not just trucks?
Yes. Rivio handles both mobile fleet assets and stationary tanks. The dashboard shows all assets — trucks and fixed tanks — in a single unified view.
Does the TEK 811 LR require a SIM card?
The TEK 811 LR has built-in cellular — consult Rochester Sensors for SIM provisioning. Rivio connects to the data stream on the cloud side.
What alerts does Rivio provide for tank level monitoring?
Rivio sends SMS, email, and push notifications for configurable events: threshold levels (e.g., 80% full), device offline, pump state changes, and more.
Does Rivio work with other Rochester Sensors models?
Rivio integrates with the TEK 811, TEK 811 LR, TEK 871, and TEK 871 LR. See our individual integration pages for each model.
