Abstract
A high pressure volumetric fluid metering device for controlling the flow of fluid from a high pressure fluid supply source to a process line includes a modulator configured to pump a predetermined volume of high pressure fluid at a predetermined flow rate and an oscillator in fluid communication with the high pressure fluid supply source. The oscillator is configured to selectively direct high pressure fluid from the high pressure fluid supply source toward the modulator and further configured to direct the predetermined volume of high pressure fluid pumped out of the modulator toward an oscillator outlet. The metering device further includes a differential pressure regulator configured to substantially maintain the pressure differential across the modulator and oscillator.
