Meters Made for Flotation Bubble Control

Fluid Components International offers the ST50 and ST100 air/gas mass flow meters for accurate measurement to control bubble production for froth flotation. According to the vendor, the ST50 and ST100 Series are calibrated for superior accuracy in FCIís NIST-approved calibration laboratory, and their thermal dispersion mass flow sensors and rugged packaging are ideal for dirty industrial environments. Designed specifically for compressed air and nitrogen flow applications, the ST50 comes with two standard calibrations. Custom calibrations are also available. The meterís all stainless steel element with Hastelloy-C tips provides protection from invasive conditions within the pipe and ensures a long service life, and its electronics are housed in a metal NEMA 4X (IP67) rated enclosure. The ST100 is claimed to be ideal for mass flow measurement within highly automated mining operations. Communication options include 4-20 mA analog, frequency/ pulse, or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485. The ST100 features a graphical, multivariable, backlit LCD display/readout. It provides local information with a continuous display of all process measurements and alarm status, as well as service diagnostics. The ST100 stores up to five calibration groups.
