ABSTRACT:
An improved flowmeter apparatus and method for accurately determining the liquid flow rate in a conduit and the mass flow rate of selected pollutant components entrained in the flow stream characterized by injecting at least two trace materials into the flow stream at a plurality of locations and, after allowing adequate time for the trace materials to reach a downstream sampling location, collecting a plurality of samples of liquid from the flow stream containing the trace materials. By comparing the concentrations of the trace materials found in the sample, the degree of mixing of the trace materials in the flow stream, and hence the accuracy of the flow stream flow rate and pollutant component mass flow rate measurements, can be evaluated. Other injecting methods for more thoroughly mixing the trace materials with the flow stream are also disclosed.
