Abstract: ABSTRACT OF THE DISCLOSURE         A lubricating delivery system includes a positive displacement lubricant pump and fluid flow measuring means for monitoring the output of the pump.  The pump is a miniature injection pump and the measuring means includes switch means responsive to movement of the check valve provided at the output of such a pump.  Because such a system provides flow measurement by a single digital input to a programmable controller, numerous pumps may be utilized to individually supply lubricant to separate portions of a machine and all may be monitored for output flow without tying up an inordinate portion of the PC input circuitry, which is typically required to additionally control the machine being lubricated.
