Mass Flow Measurement and Control
Hastings 200 Series With LFE – High Capacity Flowmeters

– Inherently Linear Response
– Excellent Rangeability
– Modular Construction
– ± 1% Full-Scale Accuracy
– Range ? 25 to 15,000 slm (Air Equivalent)


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? and a wide choice of elastomer seals make this flow meter compatible with most gases. Used in conjunction with the standard HFM-200 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.
