Abstract
The accurate control and determination of small rates of displacement of fluids are of interest in many experiments. Such problems are of particular importance in nonequilibrium investigations involving diffusion, flow of fluids, and other studies in which time is a primary variable. A relatively simple device for the predetermination and control of the rate of displacement of fluids at atmospheric and elevated pressures is described. It is believed that the rate of displacement may be maintained at a prescribed value with an uncertainty of not more than 0.05 percent and the error in the actual value of the rate is not more than twice as great.Keywords
