    • A pressure vessel comprises an enclosure in which are a liquid orifice and a gas orifice spaced from the liquid orifice. A separator divides the enclosure into two variable volume chambers. One of these is a liquid chamber communicating with the liquid orifice and the other is a gas chamber communicating with the gas orifice. The separator has a transverse wall spaced from the gas and liquid orifices and movable inside the enclosure. There is an orifice in the enclosure communicating with the gas chamber through which there is passed into the gas chamber a sensor which is responsive at one end to the presence of a liquid. In a neutral position of this transverse wall the responsive end of the sensor is nearer the transverse wall than it is to the orifice in the enclosure through which it passes into the gas chamber. The sensor preferably comprises an optical probe.
    • 压力容器包括外壳,其中是液体孔口和与液体孔口间隔开的气体孔口。 分离器将外壳分成两个可变容积室。 其中一个是与液体孔连通的液体室,另一个是与气体孔连通的气室。 分离器具有与气体和液体孔口间隔开并在外壳内可移动的横向壁。 外壳中的孔与气室连通,通过该孔通入气室,传感器在一端响应液体的存在。 在该横向壁的中间位置,传感器的响应端比其通过气室的外壳中的孔更接近横向壁。 传感器优选地包括光学探针。
