The ST100 Series Thermal Mass Flow Meter from Fluid Components International (FCI) is now available with FCI’s VeriCal In-Situ Calibration Verification System, combining advanced measurement capability with the convenience of in-situ calibration verification. It is first thermal flow meter to offer three different types of flow sensors to best match user applications.
The fast-response FPC-style features an integral flow conditioner for compressed air and clean gas applications. For wet or dirty gases, the unshrouded S-style facilitates easy cleaning and provides a smoothed response. The general purpose FP-style features a protective shroud and is the sensor used with FCI’s VeriCal in-situ calibration option.
The series is comprised of two core model families: ST meters measure both mass flow and temperature, and the STP family adds a third parameter of pressure which can be calibrated to measure virtually any process gas. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.07 NMPS to 305 NMPS with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale.
Designed for rugged industrial processes and plants, ST100 Flow Meters include service up to 454ºC and are available with both integral and remote 300 meters electronics versions. The ST100 is agency-approved for hazardous environments, including the entire instrument, the transmitter and the NEMA 4X/IP67 rated enclosure.
