Solar powered thermal mass flow meters

Fluid Components International introduces its FCI Model ST75V solar-powered Flow Meter with built-in Vortab flow conditioner. It features a no-moving parts thermal dispersion mass flow-sensing element, and provides direct mass flow measurement of the gas at this site. Its non-clogging sensor design operates over a wide flow range with low-flow sensitivity. The integral Vortab flow conditioner provides a fully developed flow profile in just seven total pipe diameters. The ST75V Flow Meter is compatible with solar power systems that provide 24Vdc power without any special modifications. It has a rugged NEMA 4X/IP67 rated enclosure, and features an inline-style flow body providing accuracy to  ±1% of reading with flow ranges from 0.04 to 560 SCFM (0.07 to 950 NCMH), depending on pipe size, and repeatability of  ±0.5 percent of reading. It is suitable for line sizes from 0.25 to 2 inches (6 to 51 mm) diameters.
The ST75V Flow Meter's flow element is constructed with a 316L stainless steel body and Hastelloy C-22 thermowell sensors to resist corrosion. It is approved for use in hazardous/explosive oil/gas production environments and carries global approvals that include: FM/CSA, Class 1, Div 1, Groups B, C, D; Class 1, Div II, Groups A-D, ATEX/IECEx Zone 1, II 2 G Ex d IIC T6 ...T3, II 2 D Ex tD A21 IP67 T90 °C...T300 °C.
