DESIGN FEATURES
The Teledyne Hastings Instruments (THI) Model HFM Mass Flowmeter represents a culmination of over 55 years of experience in designing and manufacturing reliable, high quality mass flow instruments.
The HFM 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 design features an integral filter and an easily replaceable closed loop electronics card.*
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.
Model HFM-200 with LFE
THI Model HFM-200 Flowmeters with an LFE offer the user fast, accurate measurement of high-capacity gas flows, in ranges from 25 slm up to 15,000 slm.
Our laminar flow elements (smoothed, flanged, or threaded) are available in various sizes from 3/8” up to 8”. Used in conjunction
with the standard HFM Flowmeter, these units can be combined to measure full-scale flows up to 15,000 slm and feature a typical pressure drop of 4.5” of water at full-scale flow.
*Note: After changing components, instruments require recalibration to meet accuracy specifications.
