Fluid Components International (FCI)’s ST100 Series Thermal Flow Meter features repeatability in measuring NH3 under harsh operating conditions. It has a standard wide flow turndown ratio of 100:1 (up to 1000:1 based on application), and the ability to measure mass flow, instead of volumetric flow. The ST100 Meter can be factory calibrated to measure almost any popular process gas as well as mixed gases. The technology is suitable for use in wet and dirty gas applications, having no small ports prone to fouling. The basic insertion-style air/gas meter features a thermal flow sensing element that measures flow from 0.25 up to 1000 SFPS with accuracy of ±0.75% of reading, ±0.5% of full scale. Whether the output required is 4-20 mA analog, frequency/pulse or advanced bus communications, the ST100 Series meets integration needs.
