摘要： A fluid monitoring apparatus for detecting which of a first fluid, a second fluid and a third fluid is present, the second fluid having a density less than the first fluid and the third fluid having a density less than the second fluid. The apparatus includes: a first float having a density less than that of the first fluid but greater than that of the second fluid; a second float having a density less than that of the second fluid but greater than that of the third fluid; and a sensor. The sensor is configured to detect the first float and the second float so that the position of the floats can be determined.

摘要： A density measuring device includes a moving member that can be moved in a liquid, a light emitting member and a light receiving member that receives light emitted by the light emitting member. A gap part in which the moving member is disposed in a path of light emitted from the light emitting member can be moved. A density measuring unit measures the density of the liquid based on the result of output of the light receiving member for a case where the moving member is located in the path of light emitted from the light emitting member and a case where the moving member is not located in the path of light emitted from the light emitting member.

摘要： A magnetostrictive fuel level probe includes a spring-loaded foot. The probe shaft of the fuel level probe moves up and down within the spring-loaded foot as a function of fuel density. The spring-loaded foot includes a reference magnet whose height relative to the bottom of a fuel storage tank is fixed. Currents generated by the fuel level probe allow measurement of how much of the fuel level probe is positioned above the reference magnet, and from this measurement, the buoyancy of the fuel level probe may be measured. From the buoyancy of the fuel level probe, the fuel density may be calculated.

摘要： A sensor for sensing buoyancy force within a liquid mixture stored within a storage tank and an interlock employing the sensor to prevent a respirable cryogenic mixture from being dispensed from the storage tank with an unsafe oxygen content. The sensor has a float adapted to be submerged in the liquid mixture, thereby to exert a buoyancy force referable to the density. The buoyancy force is sensed by a load cell connected to an elongated base element cantilevered from the outlet by a bracket. The mounting of such sensor ensures that the buoyancy force and therefore, the density of the liquid as dispensed will be measured as opposed to liquid density at some other location of the tank. Such sensor can serve in an interlock in which a controller responsive to the load cell and a temperature sensor, also located within the outlet, controls a valve to close the outlet when the mixture has an unsafe oxygen level.

摘要： An ink liquid supply system for an ink jet system printer includes a sub tank for introducing a new ink liquid from an ink liquid cartridge and an old ink liquid from a beam gutter included in the ink jet system printer. A float element is disposed in the sub tank, the float element having a specific gravity of, for example, 1.062 which is slightly greater than the specific gravity of a preferred ink liquid suited for the ink jet system printer. In the normal operation mode, the float element is positioned at the bottom of the sub tank. When the ink liquid viscosity increases, the float element moves upward. A detection unit is associated with the float element to develop a control signal when the float element moves upward. In response to the control signal, a dilution is added to the ink liquid contained in the sub tank in order to reduce the viscosity of the ink liquid.
摘要翻译：用于喷墨系统打印机的墨液供应系统包括用于从墨液盒中引入新墨液的副墨盒和来自喷墨系统打印机中包括的光束槽的旧墨液。浮子元件设置在副容器中，浮子元件的比重例如为1.062，其比适于喷墨系统打印机的优选墨液的比重略大。在正常操作模式下，浮子元件位于副槽底部。当墨水液体粘度增加时，浮子元件向上移动。当浮子元件向上移动时，检测单元与浮动元件相关联以产生控制信号。响应于控制信号，为了降低油墨液体的粘度，将稀释液添加到副罐中所含的油墨液体中。
