CLEARWATER — A privately held Missouri company has acquired ONICON Inc., a Clearwater-based manufacturer of energy measurement systems and metering devices, says Marvin Feldman, president of ONICON, in a statement.
Harbour Group, based in St. Louis, bought the Pinellas County company for an undisclosed price, Feldman says. “Partnering with Harbour Group and benefitting from their global resources will enable us to fortify our leading position in the HVAC market and enhance our position in additional markets."
Founded in 1987, OMICON produces devices such as BTU meters and turbine, electromagnetic, ultrasonic, thermal mass, and vortex flow meters for use in water-based heating and cooling systems, as well as products for gas and compressed air applications.
