“…Nuclear absorption (Price et al, 1976;Prezewlocki and Nizegarodcew, 1973;O'Fallon et al, 1976), electrical conductivity (Babh and Etkin, 1974;Merilo et al, 1977), electrostatic transfer (Soo and Cheng, 1970; King, 1973), light absorption (Litchfield, 1977;Soo et al, 1964), Coriolis force (Micro Motion Inc., 1978), and acoustic absorption (Epstein and Garhart, 1968; Raptis et al, 1976) have all been proposed or tested. Argonne National Laboratory is now performing an extensive study to develop instrumentation and process control for fossil demonstration plants (LeSage and O'Fallon, 1977). Part of this study deals with the measurement of coal/gas flow rates.…”

A halogen lamp light source coupled with a photodetector and op/amp pickup has been successfully employed to measure coal-air loadings and flow steadiness for values of loadings to 4.0 kg of solids/kg of air. Pittsburgh seam coal and Montana Rosebud coal have been employed in the test flows. The reduction in the signal from the op/amp is directly proportional to the solid flow rate as measured by weighing the solids flowing over a specified time period. Using a mechanical filter for flow steadiness, loadings of coal were found to be measurable with an average variation of 20%. By employing an RC filter on the signal, the signal frequencies above 1 Hz were damped permitting coal loadings to be then measured with an average variation of 10% after calibration. The meter represents an inexpensive technique to obtain instantaneous solid/gas loadings.
