Abstract
A method of determining the quantity of particulate matter suspended in a carrier gas in a pipe by measuring the frequency shift over a substantially linear range of an attenuation curve below the cut-off frequency for wave propagation, the curve being derived from measuring the attenuation of an electric field established in a conductive pipe substantially free of wave propagation.
