Rochester Sensors TEK 811
+ Rivio Fleet Dashboard.
The TEK 811 is a cellular LTE (CAT-M1/NB-IoT/2G) ultrasonic level sensor — UL 121201 C1D2 certified. Pair it with Rivio and every reading streams to a live fleet dashboard. See tank levels, GPS position, and job state for every truck or fixed asset, from any device.
What Is the Rochester Sensors TEK 811?
The TEK 811 is a cellular ultrasonic level sensor built for hazardous and non-hazardous liquid tank applications. It transmits level readings over LTE (CAT-M1/NB-IoT/2G) and carries UL 121201 Class I Division 2 certification.
📡
Cellular LTE Built In
The TEK 811 uses LTE CAT-M1, NB-IoT, and 2G fallback — no Wi-Fi or separate modem required. Readings transmit directly from the sensor over the cellular network.
🏷️
UL 121201 C1D2 Certified
Rated for Class I Division 2 hazardous locations. Suitable for fuel, chemical, and industrial liquid storage where flammable vapors may be present.
🔊
Ultrasonic Non-Contact Measurement
Ultrasonic technology measures level without touching the liquid. No moving parts, no corrosion risk, and works across a wide range of liquid types.
📏
Standard Range for Most Tanks
The TEK 811 standard variant covers typical above-ground and truck-mounted tank depths. A long-range variant (TEK 811 LR) is available for taller vessels.
How TEK 811 + Rivio Works Together
The TEK 811 handles the sensor layer. Rivio handles the cloud, dashboard, GPS, job state tracking, and alerts.
01
TEK 811 Reads the Tank
The ultrasonic sensor measures liquid level continuously, transmitting readings over LTE from the tank — no cables to the cab required.
02
Rivio Receives & Processes
Rivio ingests the sensor stream alongside GPS position and engine data. Job states (pumping, loaded, discharge, complete) are automatically classified.
03
Your Team Sees Everything Live
Dispatchers, managers, and customers see live tank levels, GPS maps, run history, and automated reports — from any browser or mobile device.

Septic, grease, chemical, food-grade, wastewater, holding tanks — Rivio works wherever the TEK 811 is deployed.
TEK 811 + Rivio FAQ
Does Rivio work directly with the Rochester Sensors TEK 811?
Yes. The TEK 811 transmits level data over LTE, and Rivio ingests that data stream alongside GPS and engine telemetry to build a complete picture of each truck or tank.
Do I need any additional hardware beyond the TEK 811?
Typically a Rivio SiteSense gateway is added to bring in GPS and engine context. For fixed tanks, the TEK 811's built-in LTE may be sufficient depending on your setup — we'll scope it during onboarding.
What liquid types is the TEK 811 rated for?
The TEK 811 is UL 121201 C1D2 certified, making it suitable for use in environments with flammable vapors. It works with wastewater, chemicals, fuel, and non-hazardous liquids.
Can Rivio monitor both trucks and fixed holding tanks?
Yes. Rivio handles both mobile fleet assets and stationary holding or storage tanks. The dashboard shows all assets in one unified view.
Is the TEK 811 the same as the TEK 811 LR?
No — the TEK 811 LR is a long-range variant with an extended measurement range for taller vessels. Rivio integrates with both. See our TEK 811 LR page for details.
