Abstract: 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 precision in fluid flow meter measurement. In addition, the devices and methods used herein can be more durable and easier to fabricate than previously known positive displacement flow meters.
Abstract translation: 本发明的实施例提供了用于测量流体体积的装置和方法。 根据一些实施例的装置包括具有可旋转地安装在其中的一对齿轮的腔室。 通过腔室的流体流动导致齿轮的旋转，使得每次旋转和/或部分旋转导致通过腔室的已知体积的流体。 定位在室外的光学传感器可通过基本透明的室壁观察旋转齿轮。 光学传感器可以观察一个或两个齿轮的光学特性，并且基于该数据，可以确定流体体积，流速和/或流动方向。 本文公开的装置和方法可以提供流体流量计测量的改进的精度。 此外，本文使用的装置和方法可以比先前已知的正排量流量计更加耐用和容易制造。

Abstract: 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.

Abstract: An ultraviolet (UV) fluorometric sensor (4) measures a chemical concentration in a sample (21) based on the measured fluorescence of the sample. The sensor includes a controller (18) 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.
