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.
