| High Flow Samplers capture all of the emissions from a leaking component to accurately quantify leak emissions rates. The left photograph shows leak measurement using a high volume sampler. Leak emissions, plus a large volume sample of the air around the leaking component, are pulled into the instrument through a vacuum sampling hose.
High volume samplers are equipped with dual hydrocarbon detectors that measure the concentration of hydrocarbon gas in the captured sample, as well as the ambient hydrocarbon gas concentration. Sample measurements are corrected for the ambient hydrocarbon concentration, and a mass leak rate is calculated by multiplying the flow rate of the measured sample by the difference between the ambient gas concentration and the gas concentration in the measured sample. High volume samplers are equipped with special attachments designed to ensure complete emissions capture and to prevent interference from other nearby emissions sources. High volume samplers measure leak rates up to 8 standard cubic feet per minute (scfm), a rate equivalent to 11.5 thousand cubic feet per day (Mcfd). Leak rates greater than 8 scfm must be measured using bagging techniques or flow meters. A single operator can measure as many as thirty components in an hour using a high volume sampler, compared with two to three measurements per hour using traditional techniques.
