摘要： According to the invention, the integrity of a product in a container (10) may be determined by the determination of a given feature of the product by means of a first measuring method (20), whereby a first physical property of the product is investigated. The given feature is additionally determined directly or by a second measuring method (30), base on a second physical property, different from the first physical property and the values for the given feature obtained by both methods are compared. Where the product is a drink in a bottle (10) and the given feature is the filling level, the first measuring method (20) can be measurement of the filling level by means of absorption of an X-ray beam and the second measuring method (30) is measurement of the change in the resonant frequency of a high frequency tuned circuit brought about by the bottle.

摘要： Apparatus for detecting the level of liquid metal within a mould and the depth of mould powder on the surface of the liquid metal, includes an array of radiation detectors positioned to one side of the mould and extending to positions above and below the expected height of liquid metal and the expected depth of mould powder within the mould. A source of radiation photons is positioned on the mould side opposite to that on which the detector array is positioned, and means are provided for counting the number of incident photons received by each radiation detector or neighbouring detectors in unit time. The number of incident photons received provides a measure of the height of liquid metal and the depth of mould powder within the mould. Signals representative of the measures of liquid metal height and/or mould powder depth may be employed as control signals for controlling automatically or periodically the liquid metal height and/or mould powder depth.

摘要： A liquid monitoring system includes chamber structure with a monitoring region (58) in which the liquid to be monitored is disposed, the monitoring region having two spaced wall portions (60, 62) and a supplemental wall portion (64). The system further includes a radiation source (110) mounted adjacent one of the spaced wall portions for directing a beam of radiation along a horizontal path, and a sensor (92) mounted adjacent the opposed wall portion for receiving radiation in a beam path. The incident radiation beam as it passes through the wall into the monitoring region is refracted at the region surface as a function of gas or liquid within the region. At a first refracting angle, the refracted beam impinges on the supplemental wall (64) and is internally reflected, the reflected radiation passing along a reflected beam path and sensed by the detector to provide an indication of the fluid in the chamber. At a second refracting angle, the refracted beam is not reflected in a direction such that radiation from the source is sensed.

摘要： A nuclear level sensing gauge for measuring the level of product in a bin utilizes a plurality of scintillators arranged in a serial fashion. A source of nuclear radiation is positioned adjacent the bin, and the scintillators, which may be bundles of one or more scintillating fibers or scintillating crystals, are positioned in a serial fashion adjacent the bin opposite the source of nuclear radiation, such that nuclear radiation passing through the bin impinges upon the bundles. Light guides carry photons emitted by the scintillators—which are indicative of radiation passing through the bin—to a common photomultiplier tube. The tube is connected to electronics which convert counts of photons from the PMT into a measure of the level of radiation-absorbing product in the bin.
