Abstract
Description
Die Erfindung betrifft einen Wärmezähler mit einem Volumenmeßteil, einem Re chenwerk, sowie je einem Temperaturfühler für den Vor- und den Rücklauf, wobei zur Übertragung der Meßwerte vom Volumenmeßteil und von den Temperaturfühlern je eine Kabelverbindung zum Rechenwerk vorgesehen ist.The invention relates to a heat meter with a volume measuring part, a Re chenwerk, as well as a temperature sensor for the flow and the return, whereby for transferring the measured values from the volume measuring part and from the temperature sensors One cable connection to the calculator is provided.
Bei derartigen allgemein als Kompaktwärmezähler bekannten Zählern sind die we sentlichen Komponenten wie Rechenwerk und Volumenmeßteil zu einer baulichen Einheit zusammengefaßt. Der Wärmezähler ist im Rücklauf einer Wärmeversor gungsanlage eingebaut. Zur Erfassung der Wärmemenge wird beim eintreffenden Volumenimpuls eine Temperaturabfrage der Vor- und Rücklauffühler ausgelöst. Die se Widerstandsthermometer müssen vom selben Typ sein und auf das Rechenwerk eingestellt sein. Das Rechenwerk verfügt also beim Eintreffen der Temperaturwerte von Vor- und Rücklauf über die daraus resultierende Temperaturdifferenz und über den mittel Impuls gemeldeten Durchfluß. Aus diesen nun bekannten physikalischen Größen läßt sich mit Hilfe noch einiger Korrekturfaktoren die Wärmemenge berech nen. Da sich jedoch ein Temperaturfühler im Vorlauf und ein Temperaturfühler im Rücklauf befindet, müssen beide mit einem Kabel mit dem Volumenmeßteil mit inte griertem Rechenwerk verbunden werden. Möchte man auf eine Kompensation der unterschiedlichen Leitungswiderstände und auf eine wesentlich teurere Vierleiter technik verzichten, so ist man gezwungen, die Leitungen beider Temperaturfühler mit der gleichen Länge zu versehen. Bei den hier beschriebenen Kompaktgeräten sitzt ein Temperaturfühler im Vorlauf und ein Temperaturfühler im Rücklauf möglichst nah am Volumenmeßteil, welches auch das Rechenwerk trägt. Durch diese Anordnung und dem zuvor erläuterten Problem bleibt eine erhebliche Kabellänge zwischen dem Rücklauffühler und dem Rechenwerk übrig und ist störend bei der Installation. Es besteht nun die Möglichkeit, die Kabellänge des Rücklauffühlers zu verkürzen und eine Widerstandskompensation im Rechenwerk einzubringen. Dabei entfällt die stö rende Kabellänge zwischen dem Rechenwerk und dem Fühler.In such counters, generally known as compact heat meters, we essential components such as arithmetic unit and volume measuring part to a structural Unit summarized. The heat meter is in the return of a heat supplier system installed. To record the amount of heat, when it arrives Volume pulse triggered a temperature query of the flow and return sensors. The Resistance thermometers must be of the same type and on the calculator be set. The arithmetic unit therefore has at the arrival of the temperature values of forward and return flow over the resulting temperature difference and over the mean impulse reported flow. From these now known physical The amount of heat can be calculated with the help of a few correction factors nen. However, since there is a temperature sensor in the flow and a temperature sensor in the Return is located, both must be connected to the volume measuring part with inte integrated calculator. Would you like to compensate for the different line resistances and on a much more expensive four-wire without technology, you are forced to use the cables of both temperature sensors the same length. In the compact devices described here sits a temperature sensor in the flow and a temperature sensor in the return as close as possible on the volume measuring part, which also carries the calculator. By this arrangement and the problem discussed above, there remains a significant cable length between the Return sensor and the calculator left and is disruptive during installation. It there is now the possibility to shorten the cable length of the return sensor and to introduce resistance compensation in the calculator. The stö cable length between the calculator and the sensor.
Es stellt sich die Aufgabe einen Wärmezähler der eingangs genannten Art anzuge ben, der ohne ein außerhalb des Wärmezählers verlaufendes Kabel des Rücklauf fühlers auskommt.The task is to suit a heat meter of the type mentioned ben, without a return cable running outside the heat meter feelers get along.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß der Temperaturfühler für den Rücklauf (Rücklauffühler) in eine Meßkammer des Volumenmeßteils ragt und daß der Rücklauffühler sowie die Kabelverbindung zum Rechenwerk innerhalb des Wärmezählers angeordnet ist.This object is achieved in that the temperature sensor for the return (return sensor) protrudes into a measuring chamber of the volume measuring part and that the return sensor and the cable connection to the calculator within the Heat meter is arranged.
Der somit in den von Wasser durchströmten Innenraum des Wärmezählers ragende Rücklauffühler schafft eine kompakte Meßkartusche. Aus dem Wärmezähler führt lediglich noch eine Kabelverbindung zum Vorlauffühler. Das bei der Montage des Wärmezählers störende Kabel des Rücklauffühlers ist ebenfalls innerhalb des Zählergehäuses angeordnet. Die Möglichkeit einer Manipulation der Meßwerte am Rücklauffühler ist durch die vorgesehene Maßnahme ausgeschlossen.The one that protrudes into the interior of the heat meter through which water flows Return sensor creates a compact measuring cartridge. Leads out of the heat meter just a cable connection to the flow sensor. That when assembling the Heat meter interfering cable of the return sensor is also inside the Counter housing arranged. The possibility of manipulating the measured values on Return sensor is excluded by the proposed measure.
Der Rücklauffühler kann ein Teil der in der Meßkammer angeordneten Komponenten sein.The return sensor can be part of the components arranged in the measuring chamber his.
Mit der Einbindung des Temperaturfühlers in derartige Komponenten wie zum Bei spiel die Mechanik oder den Volumenmeßteil wird eine platzsparende kompakte An ordnung geschaffen, die nicht störend auf die Hydraulik wirkt.With the integration of the temperature sensor in such components as for example The mechanics or the volume measuring part becomes a space-saving, compact unit order created that does not interfere with the hydraulics.
Vorzugsweise ist der Rücklauffühler in eine Tauchhülse angeordnet.The return sensor is preferably arranged in an immersion sleeve.
