Title: Innovations of James MacAllen Chalmers
Introduction
James MacAllen Chalmers is a notable inventor based in Danville, CA (US). He has made significant contributions to the field of gas flow control, holding a total of 7 patents. His work focuses on improving the accuracy and efficiency of gas flow measurement systems.
Latest Patents
One of Chalmers' latest patents is a method and apparatus for in situ testing of gas flow controllers. This innovative approach utilizes a rate of drop in pressure upstream of a gas flow controller (GFC) to accurately measure the flow rate through the GFC. The method allows for the measurement of gas flow through various controllers in production without the need for sophisticated pressure regulators or special components. Provisions are included to ensure that pressure changes during measurement do not disrupt the constant flow of gas through the GFC under test. A pressure regulator is coupled to a gas source, with the GFC positioned downstream. A pressure transducer measures the pressure in the volume between the pressure regulator and the GFC, and techniques are provided for increasing the pressure in this volume.
