Rochester Sensors TEK 871
+ Rivio Fleet Dashboard.
The TEK 871 is Rochester Sensors' ATEX-certified intrinsically safe cellular ultrasonic sensor (a combined TEK 822 + TEK 865 solution), rated UL913 C1D1 Zone 0 for the most demanding hazardous liquid environments. Pair it with Rivio for a complete cloud monitoring solution — live levels, GPS, and automated fleet reports over LTE.
What Is the Rochester Sensors TEK 871?
The TEK 871 combines the TEK 822 ultrasonic sensor and TEK 865 data logger into a single intrinsically safe cellular unit — ATEX certified and rated UL913 Class I Division 1 Zone 0. It's designed for fuel tanks, chemical vessels, and any application where ignition risk demands the highest safety rating.
🔥
ATEX / Intrinsically Safe — UL913 C1D1 Zone 0
The TEK 871 carries the highest hazardous area certification available — Class I Division 1 Zone 0. Suitable for continuous presence of flammable gases, fuel storage, and chemical tanks.
🔗
Combined Sensor + Data Logger
The TEK 871 integrates the TEK 822 ultrasonic sensor with the TEK 865 data logger in one unit — simplifying installation and reducing wiring complexity.
📡
Cellular LTE CAT-M1/NB-IoT/2G
Built-in LTE transmits readings directly from the hazardous area to the cloud — no intermediate hardware required. Same low-power cellular platform as the TEK 811 series.
🔊
Non-Contact Ultrasonic Measurement
Measures without touching the liquid — no contamination, no corrosion, no moving parts. Suitable for fuel, solvents, acids, and other aggressive chemicals.
How TEK 871 + Rivio Works Together
The TEK 871 handles hazardous-area sensing and cellular transmission. Rivio handles the cloud, mapping, job detection, alerts, and reporting.
01
TEK 871 Senses in the Hazardous Zone
The intrinsically safe sensor measures level inside fuel, chemical, or flammable-liquid tanks — transmitting safely from Class I Division 1 environments over LTE.
02
Rivio Processes & Classifies
Rivio adds GPS position, job state classification (idle, pumping, loaded, discharge, complete), and equipment context to every reading.
03
Live Dashboard for Your Whole Team
Dispatchers and managers see every asset on a live map — fill %, GPS, job state, and alerts — from any device, without being on-site.

🚛
Fuel Tanker Trucks
C1D1 rating makes the TEK 871 appropriate for fuel transport vehicles. Pair with Rivio for live fill level, GPS, and delivery confirmation.
🏭
Industrial Liquid Hauling
Chemical tankers and industrial liquid haulers benefit from intrinsically safe sensing with full cloud fleet visibility.
📡
Remote Site Monitoring
Monitor fuel and chemical tanks at unmanned remote sites over LTE — get alerts before you run out or overflow.
📋
Compliance & Audit
Automated run logs with time, volume, and GPS provide a complete audit trail for regulatory reporting without manual record-keeping.
TEK 871 + Rivio FAQ
What is the difference between the TEK 871 and TEK 811?
The TEK 871 is ATEX intrinsically safe (UL913 C1D1 Zone 0) — rated for environments with continuous flammable gas presence. The TEK 811 is C1D2 — rated for less severe hazardous areas. Rivio integrates with both.
Is the TEK 871 the same as TEK 822 + TEK 865?
Yes. The TEK 871 is a combined unit that integrates the TEK 822 ultrasonic sensor and TEK 865 data logger into one intrinsically safe cellular package.
What applications is the TEK 871 appropriate for?
Fuel storage, petroleum hauling, chemical processing, solvent tanks, and any Zone 0 location where intrinsic safety is required. If your environment mandates C1D1, the TEK 871 is the right sensor.
Does Rivio handle the cloud dashboard for TEK 871 data?
Yes. Rivio receives the TEK 871 data stream and provides a live fleet dashboard, GPS map, job state classification, volume logging, alerts, and run history.
Can I monitor both TEK 871 and TEK 811 sensors in one Rivio account?
Yes. Rivio handles mixed sensor deployments — you can have TEK 871-monitored fuel tanks and TEK 811-monitored wastewater trucks all visible in the same dashboard.
