Device for metering fluids
First Claim
1. A device comprising:
- a block having a channel connecting a fluid inlet in fluid communication with a fluid outlet;
a filter assembly within the channel;
a fluid meter within the channel at a position downstream from the filter assembly;
a check valve assembly within the channel at a position downstream from the fluid meter; and
a calibration valve assembly within a channel section of the channel between the fluid outlet and the fluid meter, the calibration valve assembly 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;
wherein the calibration valve assembly, when in the second position, is in fluid connection with a calibration channel present within the block.

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.

16. A method comprising:
-
receiving a fluid at a fluid inlet of a fluid meter assembly, the fluid meter assembly comprising a channel through which the fluid flows; metering the fluid flowing through the channel using a fluid meter; moving a calibration valve within the channel to a first or second position; when the calibration valve is in the first position, allowing passage of the fluid from the fluid meter towards a fluid outlet of the fluid meter assembly; and when the calibration valve is in the second position, blocking the passage of the fluid from the fluid meter towards the fluid outlet and allowing passage of the fluid from the fluid meter towards at least one of;
a calibration channel and a calibration outlet of the fluid meter assembly. - View Dependent Claims (17, 18, 19, 20)
