Abstract: A method and apparatus are provided for measurement of VOC emissions. The apparatus includes at least one memory including computer program code, and at least one processor. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to receive a plurality of electronic pulses based on a flow of a volatile organic compound-containing liquid through a measurement unit. The at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to generate metadata based on the received plurality of electronic pulses, store the generated metadata, and display the stored metadata. The metadata includes information relating to one of a flowrate, a total amount, and a total elapsed time of dispensing the volatile organic compound-containing liquid.
