Description
Die Erfindung bezweckt die Messung filtrierbarer Teilchen in Flüssigkeiten, z. B. in Fa-I>rikationswässern, Trink-, Speise-, Fluß wasser, I)estillaten usw. Zu diesem Zweck wurden hisher mehr oder weniger subjektive und langwierige Filtervergleichsprüfungen in der Weise vorgenommen, daß z. B. mehrere Filterproben nach ihrem Farbenaussehen beurteilt werden oder daß umständliche Wiegungen der Filter vor und nach dem Filtrieren gemacht werden. The invention aims to measure filterable particles in liquids, z. B. in Fa-I> rication waters, drinking, feed, river water, I) distillates, etc. For this purpose, more or less subjective and lengthy filter comparison tests have been used up to now made in such a way that z. B. several filter samples according to their color appearance judged or that cumbersome weighing of the filter before and after filtering be made.
Demgegenüber ermöglicht die Erfindung eine objektive Prüfung und die zahlenmäßige Erfassung des Verunreinigungsgrades. Das Wesen der Erfindung ist darin zu erblicken, daß die zu prüfende Flüssigkeit in einer Leitung unter bestimmtem Druck durch ein Filter (Filterpapier) gedrückt wird und die Zeiten bestimmt werden, die zu Anfang und am Ende der Messung jeweils für den Durchtritt einer bestimmten Wassermenge erforderlich sind. In contrast, the invention enables an objective test and the numerical recording of the degree of contamination. The essence of the invention is to see that the liquid to be tested is in a pipe under certain Pressure is pushed through a filter (filter paper) and the times are determined those at the beginning and at the end of the measurement each for the passage of a certain Amount of water are required.
Ein Gerät zur Durchführung dieses Verfahrens ist in der Zeichnung in einer Ansicht beispielsweise dargestellt. Mit I ist der Anschluß an das mit einer Drosselvorrichtung für den Druck, z. B. einem Wasserhahn, versehene Leitungsnetz, mit 2 ein Wassermengenmesser (z.B.Wasseruhr, Zähler), mit 3 ein Druckmesser, mit 4 eine Vorrichtung zum Einlegen eines Filters bezeichnet. An apparatus for performing this procedure is shown in the drawing shown in a view, for example. With I is the connection to that with a Throttle device for pressure, e.g. B. a faucet, provided pipe network, with 2 a water flow meter (e.g. water meter, counter), with 3 a pressure meter, with 4 denotes a device for inserting a filter.
Man wählt eine Gesamtdurchsatzmenge von z. B. One chooses a total throughput of z. B.
501 für ein Filterpapier von z. B. 40 mm Durchmesser, mißt am Anfang der Messung die Zeit für eine kleine Wassermenge v on z. B io 1 (Wasseruhrstand o bis lol) sowie am Ende der Messung die Zeit für die gleiche M'assermenge (Wasseruhrstand 40 bis 5Q 1) und bildet den Quotienten der gemessenen Zeiten, der ein Maß für die festzustellende Verunreinigung darstellt.501 for a filter paper of e.g. B. 40 mm diameter, measure at the beginning the measurement the time for a small amount of water from z. B io 1 (water meter level o to lol) and at the end of the measurement the time for the same amount of water (water meter level 40 to 5Q 1) and forms the quotient of the times measured, which is a measure of the represents the contamination to be detected.
Statt der Messung von Zeiten für gleiche Wassermengen am Anfang sowie am Ende der Messung und Bildung des Quotienten der Zeiten gilt als Inhalt dieses Verfahrens aucll: I)ie Messung von Wassermengen, die in gleichen Zeiten am Anfang sowie am Ende der Messung al>filtriert werden, und die Bildung des Quotienten der Wassermengen als Maß für die festzustelleiide XTerunreinigung. Instead of measuring times for equal amounts of water in the beginning as well at the end of the measurement and formation of the quotient of the times, this is considered to be the content Procedure aucll: I) ie measurement of water quantities in the same times at the beginning as well as being filtered at the end of the measurement, and the formation of the quotient the amount of water as a measure of the Xter pollution to be determined.
PATENTANSPRI,CHE: 1. Verfahren zur Messung tiltrierbarer Teilchen in Flüssigkeiten mittels Filters, dadurch gekennzeichnet, daR die zu prüfende Flüssigkeit in einer Leitung unter bestimmtem Druck durch ein Filter gedrückt wird und die Zeiten bestimmt werden, die zu anfang und am Ende der Messung jeweils für den l)urchtritt einer bestimmten Wassermenge erforderlich sind. PATENT APPLICATION: 1. Method for measuring filterable particles in liquids by means of a filter, characterized in that the liquid to be tested is pressed through a filter in a pipe under certain pressure and the times can be determined at the beginning and at the end of the measurement for each passage a certain amount of water are required.
