What ONICON Inc does

ONICON Incorporated, founded in 1987 and headquartered in Largo, Florida, designs and manufactures highly accurate flow meters and energy measurement systems for commercial HVAC and adjacent industrial applications. The company is structured as a privately held U.S. corporation, operating within the TASI Measurement division as a portfolio business, and employs between 101 and 250 people.

ONICON's product portfolio spans the principal flow measurement technologies: electromagnetic flow meters (FT-3500 insertion, FT-3000 inline), turbine flow meters (F-1000 series featuring a patented non-magnetic impedance sensing method with sapphire jewel bearings and tungsten carbide shafts), ultrasonic flow meters (F-4300 clamp-on, FT-4600 wetted inline), vortex steam flow meters (F-2000), and thermal mass flow meters (F-5400). These are paired with a BTU/energy measurement line — System-1000, System-40, System-20, and System-10 — that calculates thermal energy from flow and temperature data, plus D-100 flow displays and the FP-4400 portable clamp-on ultrasonic meter for field validation. Hardware differentiation is anchored in factory-configured products, NIST-traceable calibration, hot-tap insertion designs that avoid system shutdown, and native support for the dominant building automation protocols (BACnet, Modbus, Johnson Controls Metasys N2, Siemens Apogee P1). Underlying sensor and circuit know-how is protected by a granted U.S. patent on the electronic turbine rotation sensing system.

The company runs a sales-led, quote-based go-to-market model using a North American regional sales representative network accessed through a 'Find Your Rep' portal, with direct manufacturer support for enterprise customers. Revenue is generated predominantly through one-time hardware sales with adjacent professional services for technical support, calibration, and warranty. Target customer segments include commercial buildings, data centers and mission-critical facilities (primary), university and institutional campuses, and industrial process applications requiring measurement of liquids, steam, gases, and compressed air. The company has executed two acquisitions — Seametrics and Fox Thermal Instruments, both in 2016 — that broadened its measurement portfolio beyond HVAC, and continues to invest in product renewal, with EcoVadis Gold sustainability recognition in 2025 supporting institutional-customer procurement preferences.
