Fluid Components International (FCI) presents its ST100 Series Thermal Mass Air/Gas Flow Meter in a remote mountable configuration, well suited for applications in hazardous areas or hard-to-reach locations.

The ST100’s remote transmitter, with optional digital display, can be mounted up to 300 meters away from the flow sensor using an interconnecting cable, providing additional safety in hazardous factory areas where combustible or toxic gases might be present near the electronics. FCI’s ST100 offers outstanding flow sensing performance to deliver high adaptability and value, the company states. It is available with 4-20 mA analog, frequency/pulse, alarm relays or digital bus communications such as HART, Fieldbus, Profibus or Modbus. The ST100 Flow Meter can easily be adapted to changing needs or future upgrades with a plug-in card replacement that can be changed out by plant technicians in the field.

Universal Flowmeters Measures Any Process Gas

ST100 Series Flow Meters can be calibrated to measure virtually any process gas including dirty, wet and mixed gases. The basic insertion style air/gas meter measures flow from 0.25 to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale.

Rugged and Versatile

ST100 Series Flow Meters are designed for rugged industrial process and plant environments, including service up to 850ºF (454ºC). The ST100 is agency approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67 rated enclosure. Instrument approvals (submitted and pending) include: FM and FMc: Class 1, Division 1, hazardous locations, Groups B, C, D, E, F, G; ATEX and IECEx: Zone 1, II 2 GD Ex d IIC T4.
