Solar powered thermal mass flow meters

06 Jul 2016

Fluid Components International’s (FCI) ST75V Flow Meter is compatible with solar power systems providing 24Vdc power without any special modifications. A typical solar power system supporting up to 28 meters in an oil/gas production field requires two 50W solar panels to provide 24-hour power, even during cloudy, rainy, or snowy days. The ST75V Flow Meter, with its NEMA 4X/IP67 rated enclosure, is ideal for dirty oil and gas production field installations. It 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. The instrument 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. The ST75V meter’s transmitter outputs include dual 4-20mA analog outputs, which are user assignable to flow rate and/or temperature, a 0-500 Hz pulse output for totalized flow and a serial RS-232C I/O port. The optional digital display/readout is a two-line LCD displaying flow rate and totalized flow or flow rate and temperature. In applications with difficult access or display readability, the ST75V’s transmitter is also available to be remote mounted up to 50 feet (15m) away from the flow element inserted in the pipe.
