Abstract: Method and apparatus for optimizing the overall production efficiency of any pumping well based on accurate measurements of the time-averaged rate that fluid exists the wellhead. The improved apparatus includes temperature compensated, hermetically sealed electronic sensors that accurately measure the instantaneous rate of both pulsating and steady-state flow, and devices for processing measured flow-rate information to ascertain the performance of downhole equipment and fluid reservoirs. The apparatus is self-calibrating on any well, and automatically compensates for normal changes in both downhole equipment and reservoir performance that typically limit the operation of conventional well-control devices. The apparatus may be easily installed at ground level without major changes to existing wellhead equipment, and readily adapts to the efficient control of pumping equipment utilized with any other type of fluid reservoir.

Abstract: A lubrication fitting having a unique fluid flow control device mounted in an opening to prevent flow of fluid therethrough at all times except when specifically actuated to permit fluid flow therethrough. Upon actuation, the fluid flow control device automatically permits flow of lubricant into a reservoir, while at the same time automatically prevents flow of fluid out of a reservoir unless additionally actuated specifically for the purpose of withdrawing fluid from the reservoir. The fitting has a closure plug that has external threads that threadably engage the internal threads in a recess in the fitting. The recess in the fitting communicates with a passage in the fitting to form a continuous passage through the fitting for a lubricant being forced into a reservoir. The fluid flow control device is constructed so as to provide an essentially leak-free junction with the dispensing source of lubricant and may include a magnet to attract and remove ferrous metal particles from the lubricant.
