摘要： A method and apparatus for gas detection uses a sensor such as an electrochemical (EC) cell and includes a feedback control loop to control a pump to establish a first predetermined gas flow rate to the EC cell. The concentration of the gas at the first predetermined flow rate is measured. If the detected concentration exceeds a predetermined Alert value at the first flow rate an Initial Warning without remedial action is generated, and, the system then changes the gas flow rate before an Alarm is indicated. An Alarm is signaled only if the system verifies the first measurement. Preferably the first flow rate is set to optimize the measurement accuracy of the EC cell being used, and the second flow rate is lower than the first. Verification of an Alarm at the first flow rate may be conducted quickly by a quick-reaction process. The controller may periodically cycle the flow rates between the first and second rates for better accuracy and faster verification times.

摘要： There is provided a pinch valve system for controlling a fluid flow in a fluid flow path. The pinch valve system has an elastic sleeve member having a pair of outwardly extending elliptical folds on the circumference. The sleeve member is novel because the elliptical folds provide additional axial lengths that match the circumferential extension of the sleeve member when the sleeve member is in a pinched condition, thereby allowing the sleeve member always to be in a stress-free state. The sleeve member is novel because the inner surface is coated with a fluorocarbon material having superior chemical inertness and high operating temperature, thereby providing the elastic sleeve member with a long service life.
