Photon Control”sFocus Probe is an optical flowmeter that provides highly accurate dataindependent of gas composition or contamination of the sensingelements. Using laser beams to measure the velocity of naturallyoccurring particulates, the flowmeter is specifically developed forflare and biogas applications with highly variable flowrates and a widerange of pipe diameters. Designed with no moving parts andfeaturing a high turn-down ratio of 1000-to-1, the flowmeter is immuneto pipe vibration and acoustic noise. The flowmeter is alsointrinsically safe and compliant with ASME Code Section VIII, DivisionI.
