A century of measurement, now wireless.
Rochester Sensors has been building level gauges since 1913. The company combines that mechanical heritage with modern wireless telemetry — radar, ultrasonic, pressure, capacitive and BLE — through a single product family used in more than five million field deployments.
110+ years in level measurement
Founded in 1913 and headquartered in Texas, Rochester Sensors is one of the longest-established gauge and sensor manufacturers in the world. Float arms, dial gauges, capacitive probes, ultrasonic, radar and pressure — Rochester builds all of them in-house.
European manufacturing in Shannon, Ireland
Rochester operates sales, engineering and manufacturing sites across the US, Mexico, Belgium, UK, China and Shannon, Ireland. Shannon is the European hub for sales and product support — meaning local stock, local lead times, and EU-supported product development.
130+ products, one connected family
The Rochester range covers everything from a 6318 BLE retrofit dial on a propane tank to a TEK 880 ATEX radar on an oilfield chemicals fleet, and from a TLL155 cut-to-length capacitive probe inside a diesel generator to a TEK 766 LoRa ultrasonic on a remote water tank.
Platform-agnostic by design
Rochester devices feed data into Rochester's own Delta cloud platform (MS Azure-based) — or any third-party platform of your choice. Multi-connectivity is built in: 2G/3G, LTE CAT-M1, NB-IoT, LoRa, Wi-Fi, and BLE. Battery lives of 5–10 years are typical, and batteries are user-replaceable.

From tank to dashboard, on one product family.
Every Rochester deployment runs on the same four-step pattern. The hardware varies — radar, ultrasonic, pressure, dial, capacitive — but the workflow is the same whether you're monitoring 5 tanks or 50,000.
Sense
Choose the right measurement technology for your tank: radar for harsh fuels and chemicals, ultrasonic for general liquids, pressure for tall vessels, BLE dial for retrofit on existing Rochester gauges, capacitive for diesel.
Connect
Pick the network: NB-IoT or CAT-M1 cellular for nationwide reach, LoRa for private gateways and remote sites, BLE for short-range gateway pairing, Wi-Fi for fixed-site indoor use. Multi-connectivity is built into the product family.
Configure
Use the Rochester Universal BLE app to commission devices on-site — hold a magnet on the logo for two seconds to wake Bluetooth, then configure reporting schedule, alarm thresholds and fill/drain rates. No laptop, no cables.
Visualise
Push data into Rochester's Delta cloud (MS Azure-based) for ready-made dashboards, or send it to any platform you already use — Rochester is platform-agnostic. TITAN supports integration into your existing telemetry stack.
Five million devices, in every corner of the tank world.
Rochester Sensors hardware is deployed across oilfield chemicals, fuel distribution, propane, industrial gases, water utilities and fire protection. A small sample of the deployment patterns TITAN supports through the European range.
An 80,000-tank chemicals fleet, monitored at scale.
A major North American oilfield chemicals operator needed to monitor stock levels on tens of thousands of remote totes and tanks. Site visits were costly, deliveries were either too early or too late, and hazardous-area certification was non-negotiable.
TEK 880 radar sensors deployed across the fleet — C1D1-certified, invasive or non-invasive, with private-labelled enclosures. Data routed into the customer's own platform alongside Rochester's Delta cloud as a backup view.
Real-time inventory across the fleet, route-optimised deliveries, and a unified hardware standard across multiple chemical product lines. Cost-per-tank monitoring became competitive with the displaced platforms.
Fire-suppression tanks and open reservoirs.
A fire-protection operator needed continuous level monitoring on water storage tanks distributed across multiple sites. Manual dipping was the only existing method; tanks that failed compliance checks did so silently.
TEK 811 ultrasonic sensors on cellular for the smaller tanks, TEK 880 radar for the larger reservoirs. Alarm thresholds set at compliance minimums; SMS and email alerts wired into the site's facilities team.
Compliance reporting moved from quarterly site visits to live dashboards. Any tank falling below threshold triggers an alert within minutes. Same hardware is now under evaluation for the operator's underground tanks (TEK 898 pressure variant).
Refined-fuels distribution across a national footprint.
A fuel distributor managing thousands of customer-site tanks — forecourts, depots, farms and lubricant stores — needed accurate level data to optimise delivery scheduling and reduce run-outs.
A mixed deployment: TEK 880 radar for the bigger fuel storage tanks, TEK 822 cellular loggers for the lubricant and additive ranges with mechanical dial gauges, and 6318 BLE dials for retrofitting older Rochester mechanical-gauge install bases.
A single hardware partner across all product categories. Lubricant range delivery scheduling improved measurably; smaller fuel-store tanks moved from manual phone-based ordering to inventory-triggered top-ups.
Six verticals, one product family.
Rochester Sensors hardware is deployed across the world's tank-based industries. TITAN supports the European customer base across these six sectors with stock, integration help and platform-agnostic data delivery.
Fuels & Lubricants
Petrol, diesel, motor oils, hydraulic fluids and additives. Forecourts, depots, fleet stores, bowsers and on-vehicle tanks.
LPG & Propane
Bulk LPG storage, customer-site propane, industrial gases. Mechanical dial gauge + cellular logger combinations, or full radar.
Water & Utilities
Non-potable water, fire-suppression tanks, open reservoirs, irrigation storage, treatment works.
Chemicals
Industrial cleaning chemicals, oilfield chemicals, agri-chemicals, cleaning agents. Encrypted A-variant available where data security matters.
Agri-Food
Bulk feeds, agricultural water, on-farm fuel and lubricant stores. Silos, IBC totes, mobile tanks and static bulk storage.
Waste & Industrial
Waste oil, effluent storage, industrial process tanks, cryogenic and refrigerated storage. Generator diesel tanks and standby fuel.
Rochester Sensors questions, answered.
Is Rochester Sensors the same as Tekelek?
The "TEK" product range (TEK 766, 811, 822, 880, 920) was originally a Tekelek line and is now part of Rochester Sensors following acquisition. Older product datasheets, images and packaging may still show Tekelek branding — they are the same products, supported under the Rochester Sensors name through TITAN.
Are Rochester Sensors ATEX-certified for hazardous areas?
Yes — most flagship Rochester sensors are intrinsically safe and certified for hazardous environments. The TEK 880 radar and TEK 822 cellular logger are Class 1 Division 1 / ATEX rated for Zone 0; the TEK 811 ultrasonic is C1D2; the 6318 BLE Dial holds C1D1 / IECEx / ATEX / UKEX / CSA certifications. TITAN can advise on the right certification level for your site.
What battery life can I expect?
Typical battery life is over five years on cellular-connected products, and over ten years on radar and LoRa variants. Batteries are standard-format and user-replaceable in the field, so the device lifetime is not capped by the battery.
Do I need to use Rochester's cloud platform?
No. Rochester offers the Delta platform (built on Microsoft Azure) as an optional dashboarding service, but the hardware is platform-agnostic by design. Data can be routed to any third-party telemetry platform you already use — TITAN supports integration into common SCADA, fleet and IoT platforms.
What's the difference between the TEK 880 and the TEK 920?
The TEK 880 is the flagship cellular radar sensor — ATEX / C1D1, NB-IoT / CAT-M1 directly to a cellular network, up to 10-year battery. The TEK 920 is a newer pulse wave radar with Bluetooth Low Energy output; it's designed to pair with a separate cellular gateway or local receiver, giving radar accuracy in a smaller, lower-cost format. Choose the 880 for a one-piece cellular install, the 920 where you want to separate the sensor and the comms layer.

What is a cellular router?
An IoT cellular router is the line of communication between device and network. Cellular routers offer features such as Ethernet, Wi-Fi, serial ports, VPN security and link back-up, all of which provide a reliable connection.
These devices leverage cellular WAN connections to allow the IoT system to operate without a hard-wired connection like fibre or DSL.
Industrial Cellular Router Applications
Industrial routers are designed to handle harsh environments and withstand a wide temperature range. Robustel routers are rugged and provide reliable connectivity for various IoT applications. Our solutions can be customised and deployed across a range of industries including:
• Mining and oil and gas.
• Precision agriculture
• Digital signage.
• Smart city applications like street lighting and wastewater management.
• M2M routers for in-vehicle solutions like public transport.
• Management of energy grids and power stations.
• Intelligent parking.
• Smart city management.
Benefits
For many industries, the benefit of a cellular internet router is simple – cellular connectivity means you don’t have to run ethernet cables, fibre optic cables or any other wired connection to access the internet. However, there are more benefits, including:
Reliable. Industrial cellular routers can operate in harsh environments where wired internet is unreliable or unavailable for industries like farming, oil and gas, energy and mining. That keeps the line of communication open, avoiding costly delays and disruptions.
Fail-over. A cellular gateway can provide fail-over redundancy for critical applications, in case the wired connection fails.
Secure. Robustel’s routers support multiple VPN, providing a private network for the transmission of sensitive data.
Remote operating capabilities. Remotely configure your device to monitor and control your devices from any location.
