Abstract
Description
Die Erfindung betrifft einen Durchflußmesser mit Leitwertmessung und integrierter Auswerteelektronik. Mittels Leitwertmessungen wird die Rotation eines Flügelrads erfaßt. Zusätzlich kann mittels einer integrierten Signalverarbeitung aus dem gemessenen Leitwert und der Temperatur des Mediums ein Meßsignal zur Überwachung von Filtermedien errechnet werden. Einsatzbereiche für die Erfindung wären zum Beispiel Getränkemaschinen, Kaffeemaschinen, Umkehrosmoseanlagen oder Ionenaustauscherpatronen zur Wasseraufbereitung.The The invention relates to a flowmeter with conductivity measurement and integrated evaluation electronics. Using conductance measurements is detects the rotation of an impeller. additionally can by means of an integrated signal processing from the measured Conductance and the temperature of the medium a measurement signal for monitoring be calculated from filter media. Applications for the invention would be, for example, beverage machines, Coffee machines, reverse osmosis systems or ion exchange cartridges for water treatment.

Nachteilig am Stand der Technik ist weiterhin, daß die Vorrichtungen aus getrennten Bauelementen für die Wassermengenerfassung mittels Meßelektroden und einer Leitfähigkeitsmeßelektronik bestehen.adversely In the prior art is further that the devices from separate components for water quantity detection consist of measuring electrodes and a conductivity measuring electronics.
Die erfindungsgemäße Vorrichtung vermeidet die Nachteile des Stands der Technik dadurch, daß die Meßelektroden direkt auf der Auswerteelektronikplatine angebracht sind wodurch eine Kontaktierung mittels Feder- oder Drahtverbindungen unnötig ist. Weiterhin vorteilhaft ist daß die Meßelektrodenflächen mittels klassischer Platinenfertigungstechnik in beinahe beliebiger Anzahl, Form und Größe konturiert sein können. Weiter besonders vorteilhaft ist, daß die Elektronikplatine selbst als eine Begrenzungsfläche des Durchflußmessergehäuses eingesetzt werden kann wodurch ein sehr einfacher, kostengünstig zu fertigender, kompakter und zuverlässig arbeitende Durchflußmesser hergestellt werden kann.The Device according to the invention avoids the disadvantages of the prior art in that the measuring electrodes which are mounted directly on the transmitter board a contact by means of spring or wire connections unnecessary is. It is furthermore advantageous that the measuring electrode surfaces using classic PCB manufacturing technology in almost any Number, shape and size can be contoured. Next particularly advantageous is that the electronics board itself as a boundary surface of the flowmeter housing can be used whereby a very simple, inexpensive to be manufactured, compact and reliable working flow meter can be produced.
Die Erfindung wird im folgenden anhand eines Umsetzungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben.The The invention will be described in more detail below with reference to an example of implementation which explains other important characteristics.
Im
Durchflußmesserhalbschalengehäuse (
Besonders vorteilhaft ist, daß sich die Elektronikplatine einfach und preisgünstig in herkömmlicher Elektronikplatinentechnik herstellen und mit oberflächenmontierbaren, sogenannten SMD-Bausteinen bestücken läßt. Durch die Herstellungstechnik können die Elektroden kostengünstig in beliebiger Form, Anzahl und Größe und Oberflächenbeschichtung gefertigt werden wobei deren Kontaktierung zu den Leiterbahnen der Bestückungsseite galvanisch, löttechnisch oder mittels Durchkontaktierungsnieten erfolgen kann. Falls Nieten zur Durchkontaktierung benutzt werden kann die Nietenoberfläche selbst als Meßelektrode dienen; in diesem Fall kann eine preisgünstige, einseitig metallkaschierte Platine eingesetzt werden.Especially It is advantageous that the electronics board easy and inexpensive in conventional electronic board technology produce and with surface mount, so-called Populate SMD components. By The manufacturing technology can cost the electrodes in any shape, number and size and surface coating be made their contacting with the conductor tracks of the Plating side galvanic, soldering or Can be done by means of Durchkontaktierungsnieten. If rivets to Through-hole can be used the rivet surface even serve as a measuring electrode; In this case, one can inexpensive, one-sided metal-laminated board used become.
Die
Achse (
Eine Verrastung ist nur eine mögliche Verbindung zwischen Elektronikplatine und Durchflußmessergehäusehalbschale. Die Verbindung kann auch durch Verpressung mit einem Überwurfring oder mittel verbördelten Dorndurchführungen erfolgen. Es können auch weniger Meßelektroden als im Ausführungsbeispiel gezeigt eingesetzt werden.A Locking is just one possible connection between the electronic board and flowmeter housing half shell. The connection can also be made by crimping with a coupling ring or medium crimped mandrel penetrations done. There may also be fewer measuring electrodes than in the exemplary embodiment shown used.
