What FPI Sensors does
FPI Sensors, operating under the legal name Rochester Sensors and formerly known as Rochester Gauges, is a U.S.-based manufacturer of float level switches and liquid level sensor technology founded in 1997 and headquartered in Coppell, Texas. The company is a wholly-owned subsidiary of Amphenol Corporation (NYSE: APH) following an acquisition that positioned it within a global interconnect manufacturer's portfolio. Its product portfolio spans multi-level float switches, single point and side-mount float switches, high-temperature float switches, continuous 4-20mA loop-powered level sensors, guided wave radar liquid level transmitters, leak detection sensors, and combined level/temperature switches, with quick-connect mounting options for fast OEM integration. The core technology is electromechanical and electromagnetic sensing — float-actuated switching, guided wave radar for continuous measurement, and analog 4-20mA signaling — with no disclosed AI/ML or software-defined sensing components.
The company serves OEM manufacturers across industrial, fluid power, automotive, and tank monitoring applications, addressing use cases such as liquid level detection, continuous level measurement, fuel and water level sensing, leak detection, and combined level/temperature monitoring. Distribution runs through a dedicated Quick Turn division that handles quote-based direct sales via phone (1-800-852-9984) and email ([email protected]), with no retail or third-party distributor channel. The company holds UL, cUL, IATF 16949, hazardous locations, and Florida DOT certifications, supporting OEM qualification into regulated industrial and automotive supply chains. Pricing is not publicly disclosed and is handled through direct quote rather than published price lists. The operating footprint is North America, with no disclosed international offices or distribution outside the United States.
