Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Drehpendel lediglich auf zwei beiderseits seiner ideellen Drehschwingungsachse mit der Drehpendelmasse verbundenen Zugorganen gelagert istThe invention relates to a square root measuring device, in particular for flow meters, with a rotary pendulum, to simplify and improve the pendulum frequency of the measuring device by changing the voltage from perpendicular to the oscillating beam, to increase the functional accuracy of the device. According to the invention, this object is achieved by that the rotary pendulum only on two sides of its ideal torsional oscillation axis with the rotating pendulum mass connected traction elements is mounted

Dadurch kommen die Drehpendelwelle und deren mit Reibung behaftete Lagerung in Fortfall. Die ίο Drehschwingungsbewegungen der Pendelmasse erfolgen unbehindert durch Lagerreibung. Durch die doppelte Funktion der Zugorgane wird eine wesentliche Vereinfachung des Gerätes erzielt und eine gedrängtere Bauweise ermöglicht. Dementsprechend erhöhen sich die Empfindlichkeit und Arbeitsgenauigkeit eines solchen Gerätes.As a result, the rotating pendulum shaft and its bearing, which is subject to friction, are no longer necessary. the ίο Torsional vibration movements of the pendulum mass take place unhindered by bearing friction. Through the The double function of the pulling elements results in a substantial simplification of the device and a more compact one Construction allows. Accordingly, the sensitivity and working accuracy increase such a device.
