The ST100 flowmeter from Fluid Components International (FCI) is designed for measuring direct gas flow, including hydrogen, wet gas, mixed gases and dirty gases. The basic insertion style air/gas meter features a thermal flow sensing unit that measures flow from 0.25 to 1,000 SFPS. It can measure at high flow rates from 0 to 6,600 lb/hr at 29 to 87 psi. Communication options include 4-20mA analog, frequency/pulse or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485. 800/854-1993; www.fluidcomponents.com.
