摘要： A control valve includes an elastomeric flow tube, a plunger having first and second ends, and a pinch member connected to the first end of the plunger. The pinch member is situated adjacent the flow tube. A reference surface is positioned generally opposite the pinch member such that the elastomeric tube is squeezable between the pinch member and the reference surface to control fluid flow through the flow tube. A first guide spring is situated between the pinch member and the first end of the plunger, and a second guide spring is situated adjacent the second end of the plunger. A damper may be connected to the plunger. Further, a pressure containing member may situated about at least a portion of the flow tube.

摘要： A Coriolis mass flow sensor includes a flow sensor tube, a drive device situated relative to the flow sensor tube so as to cause the flow sensor tube to vibrate, and capacitance displacement gauges situated relative to the flow sensor tube so as to measure the twist in the flow sensor tube due to Coriolis force. In specific embodiments, electromagnetic, electrostatic, acoustic, and/or piezoelectric drives are used to vibrate the flow sensor tube. In still further embodiments, piezoelectric devices are used both to vibrate the flow sensor tube and measure the twist in the flow sensor tube. In accordance with certain embodiments of the invention, the Coriolis mass flow controller further includes an integrated flow control device adapted to receive fluid from the flow sensor tube and provide flow control.

摘要： A mass flow measurement device includes a flow sensor tube and a housing having the flow sensor tube situated therein. A drive device is positioned outside the housing for vibrating the flow sensor tube, and at least one pick off sensor is situated relative to the flow senior tube so as to measure the twist in the flow sensor tube due to Coriolis force Another mass flow measurement device includes an enclosure having first and second ends. A first sealing member is situated relative to the enclosure first end and a flow body such that the flow body and the first end are connected in a sealed manner. A second sealing member is situated relative to the enclosure second end and a user interface assembly such that the user interface assembly and the second end are connected in a sealed manner.
