Abstract: A capacitance diaphragm gauge (CDG) for measuring pressure includes a flush diaphragm mounted to a body structure via a shim or other raised perimeter portion. The diaphragm and the shim are welded to the body structure while the diaphragm is maintained at an elevated temperature. Contraction of the diaphragm as it cools pretensions the diaphragm to substantially reduce hysteresis effects. An electrode advantageously includes two portions with one portion providing excellent bonding characteristics and the other portion having temperature characteristics corresponding to the body structure and the diaphragm. An alternative CDG includes two identical electrodes with a first electrode positioned proximate to the center of the diaphragm and with a second electrode positioned proximate to the perimeter of the diaphragm. The second electrode provides a second capacitance signal that is used to compensate for changes in capacitance between the diaphragm and the first electrode caused by temperature changes.

The control valve can position the liquid in a reservoir radially outward from a valve seat and an elongated mixing chamber can be positioned within the valve seat and connected to both a carrier gas and the release nozzle.

Abstract: The output from the sensor detecting the flow rate of the fluid passing through the conduit is compared with the ceiling value and the appointed compensating signal is added to the output from the sensor to display the signal obtained on the basis of this addition result as the value of flow rate or reduce the openness of the control valve on the basis of the above described signal when the output from the sensor is larger than the threshold value, so that the mass flow meter can accurately display the flow rate even when the fluid passes in an excessive flow rate. In addition, even though the mass flow meter and the mass flow controller are fallen into the abnormal operating condition due to an excessive flow rate of fluid, they can be quickly returned to the normal operating condition.

Abstract: A part of a tube, through which a fluid passes, is cooled by means of an electronic cooling element and a flow rate of the fluid is measured on the basis of a temperature of a surface of the tube cooled. Not only can the flow rate of the liquid flowing through the tube be determined in a noncontacting manner and a very small flow rate of the liquid be determined, but also the tube is cooled so that no bubbles are generated, and thus the measurement of the liquid, which is apt to generate gases, such as low boiling point liquid, is possible. In addition, the measurement is not influenced by the gases dissolved in the liquid and merely the temperature difference resulting from the flow of the fluid, that is, the rise of the temperature of the fluid, is detected to prevent the measurement from being influenced by the installing posture of the flow meter, so that a highly accurate measurement is possible. Consequently, stable and sure controlling flow rate of liquid is possible.
