摘要： A temperature compensator modifies the output from a volumeter to compensate for the effect of temperature changes on the volume of a fluid being metered and includes a differential gear train having an output shaft that rotates at a speed equal to the rotational speed of one of its inputs, which is dependent on the volume of the fluid being measured, minus the rotational speed of its other input, which is dependent on the difference in temperature between the temperature of the fluid being metered and a standard temperature. The temperature-dependent input is controlled by a pair of reciprocating linkages, which are pivotally connected to a bellcrank, which pivots in response to a temperature-sensing device, for adjustably controlling the length of the stroke of the reciprocating linkages.
