TELEDYNE HASTINGS INSTRUMENTSEvery whereyou look” HFM-201 Flow Meter HFC-203 Flow Controller MEDIUM CAPACITY FLOWMETERS AND CONTROLLERS FEATURES • ±1% full scale accuracy1 • Input Power +/- 15 VDC or +24 VDC (specify when ordering) • Available flow ranges: 0-25 slm to 0-1000 slm (N2 Equivalent) • NIST Traceable Calibration Certificate APPLICATIONS • Leak testing • Flame Spray • Aerospace • Excellent Stability • Proven Reliability • Outstanding Zero Stability The Teledyne Hastings Instruments (THI) Model HFM Mass Flowmeter and HFC Mass Flow Controller represent a culmination of over 65 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. 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.
