Yaphank, NY, USA - COSA is excited to announce our partnership with Photon Control located in Burnaby, British Columbia. Photon Control has focused much of its research and development efforts to produce a line of optical gas flow measurement products for flare gas measurement. These flow meters are ideally suited for low-pressure applications with widely variable flow rates. Their flow measurement products use light to measure, analyze or control. These products work in the harshest, most demanding environments because light is immune to temperature extremes, electro-magnetic interference, sound, mechanical forces, etc.
