Abstract
A device for metering fluids includes a block provided with a channel connecting a fluid inlet in fluid communication with a fluid outlet. The device also includes a filter assembly within the channel and a fluid meter within the channel at a position downstream from the filter assembly. The device further includes a check valve assembly within the channel at a position downstream from the fluid meter. In addition, the device includes a calibration valve assembly within a channel section of the channel between the fluid outlet and the fluid meter. The calibration valve assembly is operable to move between a first position allowing passage of fluid from the fluid meter towards the fluid outlet and a second position blocking the passage of fluid from the fluid meter towards the fluid outlet.
