HFM-200 LFE
Low Pressure Drop, Large Flow Rates!
The HFM-200 LFE Series by Teledyne Hastings can be configured and accurately measure gas flow in a broad array of applications. Featuring reliability and stability, the 200 Series is chosen by users for its very stable performance with varying ambient conditions. A wide choice of elastomer seals make this flow meter compatible with most gases.
The HFM-200 LFE meter has flow ranges from 0-10 sccm to flows of 0-15,000 slm; provides analog outputs, and is constructed of stainless steel. The full scale range is specified by the end user. A NIST traceable calibration certificate is standard. Cleaning for oxygen service is available. Our laminar flow elements (smooth, threaded or flanged) are available in various sizes from 3/8″ up to 8″. Low pressure drops at full scale flow.
