Rochester Sensors TEK 898
+ Rivio Fleet Dashboard.
The TEK 898 is an ATEX intrinsically safe cellular pressure level sensor (C1D1 approved), designed specifically for underground and enclosed tanks — fuel, oil, chemicals, and water. It uses a submerged pressure probe instead of ultrasonic or radar, making it ideal for tanks where a top-mounted sensor isn't possible. Pair it with Rivio for a complete cloud monitoring solution.
What Is the TEK 898 Pressure Sensor?
Unlike ultrasonic (top-mounted) sensors, the TEK 898 uses a submerged pressure probe to measure liquid levels from the bottom up — making it the right choice for underground storage tanks, enclosed vessels, and applications where top access is restricted. ATEX certified, C1D1 compliant.
🧭
Pressure-Based — Bottom-Up Measurement
Submerged pressure sensor measures hydrostatic head from inside the liquid. No top-access required. Ideal for underground storage tanks (USTs).
🔥
ATEX / C1D1 Intrinsically Safe
Certified for hazardous liquid environments including fuel, oil, solvents, and flammable liquids in underground or enclosed tanks.
📡
CAT-M1 / NB-IoT Cellular
Transmits level data over LTE from underground or partially buried installations using an external antenna option for improved signal in below-grade locations.
🔌
External Antenna Option
For underground installations, the TEK 898 includes an external antenna option so the cellular signal isn't blocked by the tank or soil above.
How TEK 898 + Rivio Works
01
Pressure Probe Measures from Inside
The submerged cable-connected probe measures hydrostatic pressure at the tank bottom — calculating level without needing any access to the top of the tank.
02
LTE Sends Data to Rivio
Using CAT-M1/NB-IoT and an external antenna if needed, the TEK 898 transmits level readings from below ground to Rivio's cloud in near real-time.
03
Rivio Shows Your Full Fleet
Every underground or enclosed tank appears on the Rivio dashboard with live level, low-stock alerts, fill history, optional GPS, and delivery reports.

Where TEK 898 + Rivio Is Deployed
⛽
Underground Fuel Storage (UST)
The most common TEK 898 application — underground gasoline, diesel, and kerosene tanks at retail fuel stations, depots, and industrial sites.
🛢️
Oil, Waste Oil & Lubricants
Monitor oil and lubricant storage in underground or enclosed tanks — waste oil collection pits, hydraulic fluid reservoirs.
⚗️
Chemical & Coolant Tanks
Submerged pressure probes for chemical tanks where top-mounting is not feasible. Compatible with a wide range of liquids.
💧
Water & Wastewater
Level monitoring for underground water storage, holding tanks, and lift station wet wells where a surface-mount sensor can't be used.
🏭
Industrial Fixed Tanks
Fixed facility liquid tanks where access is from the side or bottom rather than the top — manufacturing, energy, and process industries.
📋
Compliance & Audit Trails
Automated level logs for underground storage tanks meet EPA and state regulatory requirements for UST monitoring programs.
TEK 898 + Rivio FAQ
Why use a pressure sensor instead of ultrasonic?
When you can't access the top of the tank — underground storage, side-entry only tanks, or sealed vessels — a submerged pressure probe is the practical choice. The TEK 898's probe goes in through a dip tube or access point.
Is the TEK 898 approved for underground fuel tanks?
Yes. The TEK 898 is ATEX / C1D1 certified for flammable liquids including gasoline, diesel, and kerosene — suitable for regulatory UST monitoring programs.
How does the external antenna work underground?
The TEK 898 has an external antenna port. A cable runs the antenna to a surface-mounted position for better LTE signal from underground installations.
What liquid types is the TEK 898 compatible with?
Fuel (gasoline, diesel, kerosene), oil and waste oil, lubricants, coolants, additives, and water. Chemical compatibility depends on the probe cable material — consult Rochester Sensors for specific chemicals.
Can I monitor multiple underground tanks with one Rivio account?
Yes. Every TEK 898 unit shows up as a separate asset in Rivio. You can monitor dozens of underground tanks across multiple sites in one dashboard.
How does Rivio help with delivery scheduling for USTs?
Rivio's low-level alerts and fill history let your team predict when each tank will need a delivery, eliminating manual dipstick checks and preventing runouts.
