The HFM/HFC Series of flow instruments is based on a modular design. At the heart of each instrument is an insulated thermal transfer sensor which provides enhanced zero stability. The HFC also features a two-stage, pilot-operated control valve. The instrument’s inherent linear response to flow changes and THI's long-proven reputation for quality, result in the finest flow meters and flow controllers available today. Instruments are normally calibrated with the appropriate standard calibration gas (air), then a gas conversion factor is used to adjust the output the intended gas. Special calibration for other gases, such as oxygen, helium and argon, are available u
