摘要： A system for delivering a desired mass of gas, including a chamber, a first valve controlling flow into the chamber, a second valve controlling flow out of the chamber, a pressure transducer connected to the chamber, an input device for providing a desired mass to be delivered, and a controller connected to the valves, the pressure transducer and the input device. The controller is programmed to receive the desired mass from the input device, close the second valve and open the first valve, receive chamber pressure measurements from the pressure transducer, and close the inlet valve when pressure within the chamber reaches a predetermined level. The controller is then programmed to wait a predetermined waiting period to allow the gas inside the chamber to approach a state of equilibrium, then open the outlet valve at time=t0, and close the outlet valve at time=t* when the mass of gas discharged equals the desired mass.

摘要： A flow measurement calibration system and method is presented that actively regulates the pressure of the fluid being tested. A piston is slidably mounted to an inner wall of a chamber, which has a fluid inlet port for receiving an inflow of fluid into the interior of the chamber. The piston moves through the length of the chamber in response to fluid pressure exerted by the fluid flowing into the chamber. A piston actuator imparts motion to the piston, in response to command signals from a controller. The controller is responsive to the output of a pressure sensor, which senses the fluid pressure, and a position/velocity sensor, which senses the position and velocity of the piston. The controller commands the piston actuator to dynamically adjust the position and velocity of the piston so that the fluid pressure remains substantially constant at a desired setpoint.

摘要： A pressure control system remotely controls pressure within one or more remote zones, each respectively connected to an enclosure through a conduit, by controlling flow of a fluid into and out of each enclosure. The pressure of the fluid is measured within each enclosure. An estimated pressure within each zone is computed, as a function of the measured pressure in the enclosure and known characteristics of the conduit and the zone. For each zone, an inlet proportional valve and an outlet proportional valve of each enclosure is operated so as to control the input flow rate of the fluid into the respective enclosure and the output flow rate of the fluid out of the enclosure as a function of a pressure set point and the estimated pressure, thereby regulating pressure within the zone in accordance with the pressure set point.

摘要： A system for dividing a single flow into two or more secondary flows of desired ratios, including an inlet adapted to receive the single flow, at least two secondary flow lines connected to the inlet, an input device adapted to receive at least one desired ratio of flow, at least one in-situ process monitor providing measurements of products produced by each of the flows lines, and a controller connected to the input device and the in-situ process monitor. The controller is programmed to receive the desired ratio of flow through the input device, receive the product measurements from the in-situ process monitor, and calculate a corrected ratio of flow based upon the desired ratio of flow and the product measurements. If the product measurements are not equal, then the corrected ratio of flow will be different than the desired ratio of flow.
