Signal processing and field proving methods and circuits for a coriolis mass flow meter
TL;DR: In this article, a signal processing and method for measuring a mass flow rate of a fluid flowing in conjunction with a surface of a Coriolis mass flow meter and a field-provable CME is presented.
Patent
System and method for employing an imaginary difference signal component to compensate for boundary condition effects on a coriolis mass flow meter
TL;DR: In this article, a system for compensating for a boundary condition effect on a Coriolis meter having at least two sensors for generating preliminary signals that are a function of fluid flow through the meter and employing the system or the method.
Patent
Ionization gauge with emission current and bias potential control
Larry K. Carmichael,Weber Jesse A,Henry John H,Michael N. Schott,Brucker Gerardo A,Van Antwerp Kenneth D +5 more
TL;DR: An ionization gauge that measures pressure has an electron source that emits electrons, and an anode that defines an ionization space as mentioned in this paper, and it includes a collector electrode to collect ions formed by an impact between the electrons and a gas and to measure pressure based on the collected ions.
Patent
Dynamic counterbalance system for coriolis mass flowmeters
TL;DR: In this paper, a Coriolis-type flowmeter with a dynamic counterbalance system is presented, in which a flow tube through which a fluid to be measured is allowed to flow is permitted to flow; the flow tube comprising first and second ends; a counterbalance which is vibrationally coupled to the flowtube proximate the first andsecond ends; an electromagnet device for vibrating the flow tubes and the counterbalance in opposition to one another; at least one inertial mass; and means for selectively coupling the inertial masses to the counterbalanced to alter the

Ionization gauge and pressure measuring method
カーマイケル・ラリー・ケー,Larry K. Carmichael,ウェバー・ジェシー・エー,Weber Jesse A,ヘンリー・ジョン・エイチ,Henry John H,スコット・マイケル・エヌ,Michael N. Schott,ブラッカー・ジェラルド・エー,Brucker Gerardo A,ヴァン・アントワープ・ケネス・ディー,Van Antwerp Kenneth D +11 more
TL;DR: In this article, the authors proposed an ionization gauge which reduces stress of an electron source without suffering from damage from sputtering in operation at various pressure levels, a pressure measuring method using such an ionisation gauge, and various methods in a vacuum gas atmosphere.
