Rochester Sensors TEK 733
+ Rivio Cloud Dashboard.
The TEK 733 is a GSM ultrasonic tank level sensor from Rochester Sensors — widely deployed across fuel, water, and chemical tank fleets. If your TEK 733 sensors are already sending data, Rivio is the cloud platform that turns those readings into actionable fleet intelligence. No replacement needed — just connect.
What Is the TEK 733?
The TEK 733 is one of Rochester Sensors' most widely deployed cellular tank level sensors. Using GSM radio, it sends ultrasonic level readings wirelessly — without needing local wiring or a gateway. Thousands of TEK 733 units remain in active service across fuel, water, and industrial liquid fleets worldwide.
📶
GSM Cellular — Direct to Cloud
The TEK 733 transmits level data directly over the cellular network. No local gateway or hub required — each sensor connects independently.
🔊
Ultrasonic Level Measurement
Non-contact ultrasonic sensor mounts to the top of the tank and measures liquid level without touching the contents — works with fuel, water, chemicals, and more.
💰
Significant Installed Base
Widely deployed across industrial and commercial tank fleets, the TEK 733 is a proven platform. Rivio is the cloud software many operators have been waiting for.
☁️
Cloud Dashboard with Rivio
Rivio ingests TEK 733 data and presents it as a live fleet overview — every tank level, every fill event, alarm history, and consumption trends in one place.
How TEK 733 + Rivio Works
01
Your TEK 733 Is Already Sending Data
If your TEK 733 sensors are powered and on a network, they're already transmitting level readings. Rivio connects to that data stream directly.
02
Rivio Receives & Stores Every Reading
Rivio's ingestion layer accepts TEK 733 data and stores it in an organised cloud database — every sensor, every reading, timestamped and queryable.
03
Fleet Dashboard Goes Live
The dashboard activates immediately. See every tank in real time. Set up alarms. Filter by location, product, or fleet group. Export fill history.
Common TEK 733 Questions
Can I keep my existing TEK 733 sensors and add Rivio?
Yes. Rivio connects to existing TEK 733 data feeds. You don't need to replace sensors — just connect your account, and the dashboard populates from your active sensors.
Is the TEK 733 still supported for new installations?
Rochester Sensors still manufactures and supports the TEK 733. If you have new tanks to instrument, the TEK 733 remains a viable option. For new deployments, the TEK 811 (4G CAT-M1/NB-IoT) is the current-generation cellular model.
What happens to my data when the GSM network changes?
If your 2G/3G carrier sunsets their network, you may need to migrate to a 4G sensor. Rivio's platform makes the migration seamless — new sensors just appear in the same dashboard without any re-setup of alerts, groups, or history.
Can I mix TEK 733 and newer sensors in the same Rivio account?
Absolutely. Rivio normalises data from all Rochester Sensors models — TEK 733, TEK 811, TEK 871, TEK 880, and more — into a single fleet view. Mixed fleets are fully supported.
Where TEK 733 + Rivio Is Deployed
⛽
Fuel & Diesel Fleets
Remote fuel tank management at generators, construction sites, mining pads, and industrial depots where TEK 733 units have been running for years.
💧
Water Tank Monitoring
Municipal and commercial water storage tanks monitored with TEK 733 sensors — Rivio adds reporting, alarms, and consumption analytics.
⚗️
Industrial Chemicals
Process chemicals, coolants, and industrial fluids already monitored with TEK 733 sensors continue uninterrupted when connected to Rivio.
🚚
Road Fuel & Fleet Depots
Fleet fuel bays and road tanker depots with existing TEK 733 installations connect to Rivio for supply chain visibility and audit reporting.
🔧
Maintenance & Upgrade Planning
Rivio's mixed-fleet support means you can migrate from TEK 733 to TEK 811 sensor by sensor, at your own pace, without disrupting the dashboard.
📋
Compliance & Reporting
Automated fill history, alarm logs, and daily level reports — Rivio provides the audit trail that many compliance frameworks require.
