What Rochester Gauges does

Rochester Gauges, now operating as Rochester Sensors following an October 2025 rebrand and acquisition by Amphenol Corporation (NYSE: APH), is a US-headquartered industrial sensor manufacturer specializing in liquid level measurement for fuels, gases, chemicals, water, and specialty liquids. Founded in 1913 and headquartered in Coppell, Texas, the company employs 501-1000 people across manufacturing and sales facilities in the US, Mexico, Belgium, the UK, Ireland, and China, serving 14 end-market verticals including agriculture, LP gas/NH3, cryogenics, on-highway truck and bus, marine, mining, power generation, railcar, refrigeration, and recreational vehicles.

The company's technology portfolio spans nine sensing modalities — guided wave radar, free space radar, capacitance, angle position, reed switch, ultrasonic, swing float arm, spiral float, and hydrostatic pressure — supported by nearly 200 issued patents accumulated over more than 100 years of operation. Key product lines include the e-Dial digital gauge indicator for propane transport and bulk storage, the TEK-series radar monitors (TEK 880 cellular, TEK 920 PulseWave BLE), the SureSense capacitive propane sensor, the 6200/6300/9800/9830/9840 series industrial gauges, and TLL-series capacitive liquid level sensors. The company holds IATF 16949:2016 certification at its Texas and Mexico facilities (December 2023) and FCC certification for its cellular tank monitor.

Rochester Sensors generates revenue primarily through hardware sales of sensors, gauges, and wireless monitoring devices sold direct to OEMs and industrial customers through four regional sales networks, plus through the Digi-Key global distribution marketplace for smaller-volume and individual buyers. Pricing is quote-based and not publicly disclosed. The company has pursued a multi-year inorganic growth strategy through acquisitions of FPI Sensors (2019), Fozmula (2019), Concept Technology, and Tekelek Europe (May 2023), and is now positioned within Amphenol's global sensor and interconnect platform following the October 2025 acquisition.
