ABSTRACT:
The invention relates to a fluid-volume measuring apparatus with a device for temperature-dependent volume conversion. The device contains a temperature sensor with a plunger attached to the fluid-volume measuring apparatus, a motion-transmitting device acted upon by the temperature sensor and a regulating transmission, controlled by the motion-transmitting device and forming part of a summing mechanism driven by the volume-measuring apparatus. The motion-transmitting device includes a carriage movable transversely to the direction of motion of the plunger of the temperature sensor and transversely to the linkage of the regulating transmission. The movable carriage has inclined cam surfaces interacting with a temperature sensor and the regulating transmission. The contours of the cam surfaces are configured with regard to the dependence of the coefficient of thermal expansion of the fluid to be measured on the particular liquid temperature. The cam surfaces are formed either directly by the edges of the carriage or by control members supported by the carriage.
