A field study was conducted to evaluate two commercially available beta gauge instruments for measuring particulate mass concentrations in stationary source emissions. Performance of the instruments was compared with a manual method of measurement at a ferrite rotary-kiln calciner, at a slurry cement kiln with an electrostatic precipitator, and at an oil-fired boiler. Tests were conducted over a 168-hour period to establish instrument accuracy, calibration error, drift and system reliability. Descriptions of the instruments, test programs and test sites are presented together with a detailed summary of the experimental data. The accuracy of the beta gauge instruments was strongly dependent upon the sampling characteristics of the extractive probes. The instruments tested were not capable of correctly measuring the particulate concentration in the stack, nor of operating continuously for a 168-hour period. In the case of the cement kiln, the particle concentration measured by the beta gauge instruments correlated well with the concentration determined from the filter catch portion of the manual method, but not with the fiber plus probe catch. Particle deposition in the probe of the beta instruments was as high as 86% (average) for the cement plant emissions.
