Work conducted under Phase III has demonstrated the feasibility of using ESR and NMR techniques for on-stream coal flowmetering and analysis and has resulted in the development of an Evaluation Model which incorporates both ESR and NMR detectors to sense pneumatically transported coal flowing through a 3/8-inch pipe. Sensory data required to satisfy equations for flowmetering and analysis have been made available in the instrument. A computer program to perform the data processing and to compute the relevant coal parameters from the sensed ESR and NMR data has been developed and used in the integral microcomputer of the instrument. Laboratory data has verified the operation of the instrument and the computer program has provided readouts of selected properties of three types of coal on the digital panel meter.
