The ST75 gas mass flow meter built with no moving parts is used for accurate direct mass flow measurement. It also offers a monitoring solution for fuel gases, air, compressed air, inert and other gas flows within industrial processes. The device is available in nine different sizes for direct, in-line flexible installation in line sizes from 1/4 to 2 inch [ 6 to 51mm]. ST75 features precision lithography structured platinum RTD sensors embedded in FCI’s equal mass thermowells combined with microprocessor electronics and precise actual gas calibration to outstanding flow measurement performance. ST75’s direct mass flow measurement is designed based on FCI’s proven thermal dispersion technology, thus significantly eliminates the space and expenses of any additional sensors required by inferred technologies. The module with its 100:1 turn down and flow ranges from 0.01 to 559 SCFM [0.01 to 950 NCMH], offers wide flow range, from low to high flow conditions.
