We design and manufacture high-performance thermal mass flow meters for nearly every gas or liquid application.
Our mission is simple. We use state-of-the-art technology and features to deliver the highest performance reliability and confidence for any thermal flow meter user.
In 1959, Thermal Instrument was born in the basement of founder Fred Curran’s home. Over the last 6 decades, we’ve grown into what we are today - a leading provider of thermal mass flow meters.
After Fred Curran’s passing his son Joe Curran took over the family-run business with help from his sister Mary. Today we have 12 incredible full-time employees that continue to support our current customer base.
We focus on various mass flow meter applications. No matter the application you can count on us to already have a solution figured out.
