221 | Microvolume liquid handling system | EP97108726.7 | 1997-05-30 | EP0810438A2 | 1997-12-03 | Pelc, Richard E.; Chibucos, Nicholas S.; Papen, Roeland F.; Meyer, Wilhelm J. |
A low volume liquid handling system is described which includes a microdispenser employing a piezoelectric transducer attached to a glass capillary, a positive displacement pump for priming and aspirating transfer liquid into the microdispenser, controlling the pressure of the liquid system, and washing the microdispenser between liquid transfers, and a pressure sensor to measure the liquid system pressure and produce a corresponding electrical signal. The pressure signal is used to verify and quantify the microvolume of transfer liquid dispensed and is used to perform automated calibration and diagnostics on the microdispenser. In another embodiment of the low volume liquid handling system, a system reservoir is connected with tubing to a pressure control system for controlling the liquid system pressure in the system reservoir. The system reservoir is coupled to one or more microdispensers through a distribution tube having a branched section for each microdispenser. In this embodiment, each microdispenser is coupled to its own flow sensor and microvalve to enable a system controller to respectively measure and control the flow of liquid in the each microdispenser. |

Détecteur (1) optique du débit d'un liquide en écoulement à partir d'un ajutage (20) placé au sommet d'un récipient tubulaire transparent (15), ledit liquide étant déchargé par le fond de ce récipient. Le détecteur comporte une sonde (4) couplée au récipient (15) et pourvue d'un transducteur opto-électronique (40) comportant un photoémetteur (41) et un photodétecteur (42), sa trajectoire optique (45) traversant le récipient et croisant la trajectoire (30) suivie par le liquide en écoulement. Le détecteur (1) comporte également une unité électronique (12) pourvue d'un circuit de traitement (57) recevant à son entrée le signal produit par le photodétecteur (42), et produisant à sa sortie un signal de commande qui est une fonction des variations dans le temps du signal d'entrée. On compare ce signal de commande à un seuil de référence de manière à générer un signal d'alarme indiquant une insuffisance de liquide en écoulement. | ||||||

224 | Verfahren und Vorrichtung zur Messung eines der Masse eines Milchpfropfens entsprechenden Wertes sowie des entsprechenden Milchflusses | EP92105227.0 | 1992-03-26 | EP0509288A1 | 1992-10-21 | Hoefelmayr, Tilman, Dr.; Maier, Jakob |
Es wird ein Verfahren und eine Vorrichtung angegeben, mit der beim Melken, bei dem die Milch intermitierend in Form von Milchpfropfen abgeführt wird, die Masse der einzelnen Milchpfropfen genau bestimmt und daraus der jeweilige Milchfluß bestimmt werden kann. Eine solche Meßvorrichtung eignet sich insbesondere als ein Indikator, mit dem das Unterschreiten eines vorbestimmten Milchflusses am Ende des Melkzyklus angegeben werden kann. Wird jedoch zusätzlich auch die Geschwindigkeit der einzelnen Milchpfropfen gemessen, so wird ein äußerst einfacher Milchflußmesser erhalten, der den Milchfluß auch über den gesamten Melkzyklus verhältnismäßig genau messen kann. |

226 | Liquid-flow measuring device and method particularly useful for drip chambers | EP83103280.0 | 1983-04-02 | EP0121578A1 | 1984-10-17 | Leibinsohn, Saul |
A liquid-flow measuring device particularly useful as a drip chamber for infusion administration sets includes a housing having an internal chamber for accumulating the liquid dripping thereinto by gravity introduced via an inlet port which terminates in a first bore leading to a second bore. The housing further includes an air return leading to the juncture of the first and second bores, such that the liquid flowing through the first bore forms a liquid column in the second bore which liquid column grows by gravity until it breaks and drops into the chamber, the length and/or rate the liquid columns grow before passing into the chamber thereby providing a measurement of the rate of flow of the liquid through the device. |

A counter (32) counts the time intervals of falling instilled drops in response to a signal issue each time a falling instilled drop is detected. A memory (33) is supplied with data representing the quantities of falling instilled drop corresponding to the time intervals at which the drops fall. The data corresponding to the time intervals thereof which have been counted by the counter (32) are read out of the memory (33). The data thus read out are accumulated to determine the total quantities of the drops. |

A system for monitoring non- volatile residue concentrations in ultra pure water includes a nebulizer for generating an aerosol composed of multiple water droplets, a heating element changing the aerosol to a suspension of residue particles, and a condensation particle counter to supersaturate the dried aerosol to cause droplet growth through condensation of a liquid onto the particles. The nebulizer incorporates a flow dividing structure that divides exiting waste water into a series of droplets. The droplets are counted to directly indicate a waste water flow rate and indirectly indicate an input flow rate of water supplied to the nebulizer. The condensation particle counter employs water as the condensing medium, avoiding the need for undesirable chemical formulations and enabling use of the ultra pure water itself as the condensing medium. | ||||||
