摘要： A UV absorption spectrometer includes a housing, a controller, and a sensor unit including an ultraviolet light source, an analytical area in an analytical cell or in running water or gaseous medium, and an UV wavelength separator including a UV detector. An ultraviolet light in a wavelength range of 200-320 nm emits from the light source through the analytical area to the wavelength separator, and the controller transforms output signals from the UV detector into absorbance values or optical densities for two or more wavelengths in the wavelength range, calculates differences of said absorbance values or optical densities, determines a concentration of a chemical in the solution with calibration constants found for a known concentration of the chemical and said differences of said absorbance values or optical densities.

摘要： An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.

摘要： Embodiments of the invention provide devices and methods for measuring fluid volume. Devices according to some embodiments include a chamber, having a pair of gears rotatably mounted therewithin. Fluid flow through the chamber causes rotation of the gears, such that each rotation and/or partial rotation results in a known volume of the fluid passing through the chamber. An optical sensor positioned outside of the chamber, can view the rotating gears through a substantially transparent chamber wall. The optical sensor can view an optical characteristic of one or both of the gears, and based upon this data, fluid volume, flow rate, and/or flow direction can be determined. Devices and methods disclosed herein can provide for improved preci-sion in fluid flow meter measurement. In addition, the devices and methods used herein can be more durable and easier to fabri-cate than previously known positive displacement flow meters.

摘要： An ultraviolet (UV) fluorometric sensor measures a chemical concentration in a sample based on the measured fluorescence of the sample. The sensor includes a controller, at least one UV light source, and at least one UV detector. The sensor emits UV light in a wavelength range of 245-265 nm from the light source through the sample in an analytical area. The UV detector measures the fluorescence emission from the sample. The controller transforms output signals from the UV detector into fluorescence values or optical densities for one or more wavelengths in the wavelength range of 265-340 nm. The controller calculates the chemical concentration of the chemical in the sample based on the measured fluorescence emissions.
