What Tekelek does
Tekelek, founded in 1995 and headquartered in Shannon, Ireland, is now operating as Rochester Sensors Europe following its acquisition by Rochester Sensors (formerly Rochester Gauges, founded 1913). The company designs and manufactures tank level monitoring sensors and remote monitoring solutions, with a product portfolio spanning ultrasonic, radar, and pressure-based sensing technologies. Its TEK-series sensors support a broad range of communication protocols including LTE CAT-M1, NB-IoT, GSM, Wi-Fi, LoRa, LoRaWAN, Sigfox, and RF, with many products certified for hazardous locations under ATEX, C1D1, and C1D2 standards. The portfolio is complemented by the Delta Portal cloud-based monitoring platform and the Apollo Smart software solution, which together enable remote data visualization, analytics, and sensor management. With over 6 million sensors deployed across 70 countries, Rochester Sensors Europe serves industrial customers in fuels and lubricants, propane/LPG, chemicals, water and wastewater, agriculture, waste management, liquid terminals, and broader energy markets.
The company operates under a hybrid revenue model combining hardware sales (sensor devices and accessories) with recurring subscription revenue from its cloud monitoring platform. Go-to-market is sales-led and direct, leveraging the company website, dedicated sales team, and industry event participation (e.g., ILTA — International Liquid Terminals Association), with distribution further amplified through Rochester Sensors' six global locations and Amphenol Corporation's worldwide footprint. Tekelek/Rochester Sensors Europe is part of Rochester Sensors LLC, which is itself a member of Amphenol Corporation (NYSE: APH), a Fortune 500 interconnect, sensor, and antenna conglomerate. The company holds a dense set of compliance certifications (PTCRB, Verizon, Swisscom, FCC, RED, EMC, ISED, ISO/IEC 27002) and is a member of the LoRa Alliance, positioning it within the LoRaWAN IoT ecosystem.

Tekelek competitors and assessment
Company assessmentDirect peers
- Endress+Hauser: Global process instrumentation specialist with deep level-measurement portfolio (radar, ultrasonic, capacitance, hydrostatic). Closely comparable to Tekelek on end markets (fuels, chemicals, water/wastewater) and on hazardous-environment certifications.
- Enevo: Smart-waste management sensor and analytics provider, direct peer for Tekelek's TEK 839 LoRaWAN ultrasonic waste-bin sensor. Targets municipal and commercial haulers seeking to optimize collection routes via remote fill-level data.
- KROHNE: Process instrumentation specialist with a strong level-measurement line (radar, ultrasonic, guided radar). Overlaps with Tekelek in chemicals, oil & gas, and water tank monitoring with comparable hazardous-area certifications.
- BinMaster: U.S.-based manufacturer of level sensors and inventory management solutions for bins, tanks, and silos. Direct overlap with Tekelek's ultrasonic bin/tank sensors (including TEK 839 waste-bin sensor) across agri, waste, and industrial verticals.
- Vega Grieshaber (VEGA): German-headquartered manufacturer of level, switching, and pressure measurement instruments for liquids and bulk solids. Direct competitor in industrial tank level sensing with similar certification-driven go-to-market across chemicals, water, and process industries.
Broad incumbents
- Emerson (Rosemount): Diversified industrial automation major with Rosemount level and pressure instrumentation. Serves the same fuels, chemicals, and water end markets as Tekelek but as part of a much broader portfolio of valves, automation, and software.
- Honeywell Process Solutions: Process-industry incumbent offering level and pressure instrumentation as part of its broader Experion/DCS ecosystem. Overlaps with Tekelek in fuels, chemicals, and terminal-automation environments.
- Yokogawa Electric: Industrial process-control and instrumentation incumbent with level sensors sold into oil & gas, chemicals, and water. Competes with Tekelek across hazardous-location and large-tank applications as part of its broader DCS/instrument portfolio.
- Siemens (Process Instrumentation): Diversified industrial conglomerate offering SITRANS level, pressure, and weighing instrumentation alongside automation and digital industries portfolios. Competes with Tekelek on tank monitoring in process and water/wastewater markets.
Emerging players
- Sensoneo: European smart-waste-management sensor company combining ultrasonic waste-bin sensors with data analytics. Closely comparable niche competitor to Tekelek's waste-bin product line, particularly in EU smart-city deployments.
