Se proporciona un método y aparato para medir la masa de un gas bajo presión utilizando un oscilador piezoeléctrico. El gas se contiene en un contenedor (100) a presión que tiene un volumen (V) interno fijo y el oscilador (202) piezoeléctrico se sumerge en el gas dentro del contenedor (100) a presión. El método comprende: a) utilizar el oscilador (202) piezoeléctrico para medir la densidad del gas dentro del contenedor (100) de alta presión; b) determinar, a partir de la medición de densidad y a partir del volumen (V) interno del contenedor a presión, la masa del gas dentro del contenedor (100) a presión. Al proporcionar tal método, el contenido verdadero (es decir, masa) del fluido en un contenedor a presión tal como un cilindro puede medirse directamente sin necesidad de compensar factores tales como temperatura o capacidad de compresión. Esto permite una determinación de masa a través de derivación directa de la densidad del gas en el cilindro, reduciendo la necesidad de sensores adicionales o de que se realicen cálculos complejos.

Valve assembly and valve stock assembly

FIELD: machine building. SUBSTANCE: valve assembly includes valve body forming a fluid medium flow channel. Valve sealing housing is arranged in fluid medium flow channel and provided with possibility of functioning between open position allowing the flow passage and closed position not allowing the flow passage. Valve stock has a free end and an interacting end. The latter interacts with valve sealing housing so that rotation of valve stock can control the valve sealing housing between open and closed positions. Measuring channel passes through the valve stock from free end to the interacting end. Thus, measuring channel is in connection of fluid medium to fluid medium channel at least when it is open. Note that at least one sealing element is located inside the measuring channel. Valve stock assembly is described.

Device to shut off and open fluid flow and appropriate method

FIELD: transport. SUBSTANCE: proposed device comprises main opening arranged between fluid inlet and outlet, main opening main shutoff member to displace between closing and opening positions, and shutoff member actuator. Said shutoff member, in closing position, is located to make increased inlet fluid pressure generate pressure retain shutoff member on closing position. Fluid overflow channel is arranged between said fluid inlet and outlet to be closed by said shutoff member. Said main shutoff member allows releasing from closing position so that actuator does not apply force to main shutoff member to allow fluid overflow by said actuator. Opening force acts on main shutoff device to make said member stay in closing position solely if fluid pressure exceed preset threshold.
