TELEDYNE HASTINGS INSTRUMENTS LOW CAPACITY FLOWMETERS AND CONTROLLERS DESIGN FEATURES The Teledyne Hastings Instruments (THI) Model HFM Mass Flowmeter and HFC Mass Flow Controller represent over 55 years of experience in designing and manufacturing reliable, high quality mass flow instruments. The HFM/HFC Series flow instrument can be set up to measure and control any of a wide variety of gases under many different pressure conditions as required. The Models HFM-210 and HFC-212 were specifically designed to meet the footprint dimensions of the Tylan® FC-280 model. They are based on refinements to the existing Hastings 200 Series flow product line. The HFM/HFC Series of flow instruments is based on a modular design. At the heart of each instrument is an insulated thermo electric sensor which provides enhanced zero stability and allows installation in any orientation plane in most low pressure applications. This sensor is designed to be removable/replaceable in the field to virtually eliminate long down time due to clogging. Additionally, the HFM/HFC design features an integral filter and an easily replace-able closed loop electronics card.* The HFC also features an externally adjustable valve with easily replaceable flow orifices. All of these standard features, when coupled with the instrument’s inherent linear response to flow changes and THI’s long-proven reputation for quality, result in the finest flowmeters and flow controllers available today. Optional Features Fittings O-ring seals Enhanced response time Enhanced EMF stability High pressure rating (1000 psig) 4-20 mA converters Cleaned for oxygen service Accessories Power supplies/readouts Interconnecting cables *Note: After changing components, instruments require recalibration to meet accuracy specifications.
