ABSTRACT:
Means for measuring the flow of a stream of fluid and the resistance to said flow. The means can be powered by the fluid whose flow is being measured. First axis motor means moves a chart in response to total flow, and second axis motor means moves marker means on said chart in response to variations in backpressure caused by resistance to flow out of the means. Examples are measuring the muscular response of the urethra and of the bladder.
