The merger combines the companies' experience in process instrumentation and cloud-based monitoring to create a comprehensive provider of flow, level and asset monitoring solutions.
No financial details were disclosed, and the companies said their respective executive structures will remain. Privately held, the combined company will operate under the Hawk brand.
One benefit of the merger is the establishment of a manufacturing base in the Americas, according to Hawk president Jack Evans.
"By combining Hawk's award-winning measurement technology together with Flo-Corp's measurement monitoring solutions within a subscription-based platform, we are increasing our ability to provide unmatched customer support, innovative technologies and system solutions," he said.
Flo-Corp's Les Richards added that the merging of the companies could be likened to a joining of like-minds and philosophies - both with a clear goal of increasing capabilities and providing any available need for level measurement, flow, process data collection, remote information distribution and fibre-based sensing solutions.
"This merger will further facilitate a broader product portfolio, technical knowledge, and support infrastructure," he said.
"Together we will lead the way in providing industry required solutions, reliably and simply."
Hawk Measurement Systems was established in Melbourne, Australia in 1988. Flo-Corp began as a distribution company in 1989.
