Abstract
A system for precisely measuring the amount of fluid discharged by a pulsating fluid flow device such as a pump, or the like. The discharged fluid is collected in a container and the amount collected is sensed by a transducer which provides a corresponding signal. The signal is processed for determining the amount of fluid collected for a predetermined number of fluid flow pulses and for automatically starting and stopping measuring cycles. The arrangement is such that continuously updated measurements are provided and are entrained in the collecting container has no effect on the measurements.
Claims5
A system for measuring fluid flow from a pulsating fluid flow-device, comprising:
- means connected to the pulsating fluid flow device for collecting the fluid flowing therefrom;
- means including transducer means coupled to the collecting means and responsive to the amount of fluid collected thereby for providing a signal corresponding to the collected fluid and filter means connected to the transducer means for removing high frequency components from the signal therefrom;
- counter means coupled to the pulsating fluid flow device for counting the number of fluid flow pulses therefrom and for providing a corresponding signal;
- means including a comparator connected to the filter means for comparing the signal therefrom to predetermined "high" and "low" limits and providing a first control signal when the signal from the filter means is at the "low" limit and a second control signal when the signal from the filter means is at the "high" limit;
- means coupled to the fluid collecting means for regulating fluid intake thereto and fluid outlet therefrom;
- and
- controlling means connected to the regulating means, the means for providing control signals and the counter means, and responsive to the first control signal for controlling the regulating means for regulating fluid intake to the collecting means, and responsive to the second control signal and the signal from the counter means for controlling the regulating means for regulating fluid outlet from the collecting means.
