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.
