TELEDYNE HASTINGS
INSTRUMENTS
DESIGN FEATURES
The Teledyne Hastings Instruments (THI) Model HFM Mass Flowmeter and HFC Mass Flow Controller represent a culmination of 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 a two-stage, pilot-operated control valve.
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.
