TELEDYNE HASTINGS INSTRUMENTS DESIGN FEATURES The Teledyne Hastings Instruments (THI) Model HFM Mass Flowmeter and HFC Mass Flow Controller represent over 60 years of experience in designing and manufacturing reliable, high quality mass flow instruments. 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. 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 replaceable 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 THIs’ 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 with integral Flow Totalizers & Alarm Set Points Interconnecting cables *Note: After changing components, instruments require recalibration to meet accuracy specifications.
