Patent
System and method for a mass flow controller
TL;DR: In this article, a system and method for controlling a mass flow controller to have a constant control loop gain under a variety of different types of fluids and operating conditions, and for configuring the controller for operation with a fluid and/or operating conditions different from that used during a production of the mass flow controllers is presented.
Patent
Method and apparatus for providing a determined ratio of process fluids
TL;DR: In this article, a fluid flow control system that includes a fluid inlet to receive a flow of process fluid and a plurality of fluid outlets is presented, where the first fluid outlet provides a first predetermined portion of the flow, and the at least one second fluid outlet provided the remaining portion.
Patent
Flow sensor signal conversion
TL;DR: In this paper, a method of obtaining at least one representation of a characteristic function of a sensor from a test fluid during calibration of the sensor according to a sensor model has been proposed.
Patent
Multi-gas flow device
TL;DR: In this paper, a system and method of characterizing or controlling a flow of a fluid is provided that involves a sensor conduit and a bypass, where a plurality of fluids may be utilized in the flow control device based on characteristic information of the device generated during calibration thereof.
