A flash photography method for the measurements of the fluid flow dynamic of a fluid dispensing system

In this paper, we present a flash photography method for the measurements of the fluid flow dynamic of a fluid dispensing system. A fluid dispensing system is one of the key processes to deliver fluid materials to various positions in assembly parts of several manufacturing industries. A dispensing process is a complicated dynamic process and time-dependent. The parameter identification of a fluid dispensing model by using with measurement values of the accumulated final volume is usually employed. This technique may not provide the satisfactory results. To improve the accuracy of the parameter identification, the fluid flow measurements based on the flash photography methods is proposed. The experiments with various fluid levels inside a syringe were carried out to evaluate the performance of the proposed system. The pressure dependent fluid flow rate curve constructed from the measurement values is presented, to identify the parameters associated with the model. The measured parameters are consistent with the fluid properties reported in the literature.
