THERMAL INSTRUMENT was one of the first manufacturers of thermal flowmeters for liquids and gases, solving flow metering problems over the entire world since 1959.


THERMAL FLOWMETERS offer the advantages of a completely unobstructed flow path, with the sensors never directly in contact with the flowing medium.






THERMAL FLOW PROBES insert directly into flow stream and are ideally suited for stacks, irregularly shaped lines and square ducts. There are no apertures to become clogged with particles or distorted by heat and the ruggedly designed single probe can be hot tapped into the system.
