Toilet mounted urine flow meter

A collector for a urine flow meter in which a pressure transducer senses an air pressure within the collector which varies in accordance with the volume of urine in the collector, comprising:

• a mouth portion dimensioned to fit within a toilet bowl and having walls which slope downwardly and inwardly from an open upper end to an open lower end;
• a neck portion connected to the lower end of the mouth portion and extending downwardly therefrom, the neck portion having an open upper end and a substantially closed lower portion, a first aperture being formed in a sidewall of said lower portion;
• a pressure sender having a lower end in communication with the lower portion of the neck portion and an upper end above the neck portion suitable for connection to the pressure transducer so that a urine flow entering the mouth portion accumulates in the neck portion and produces the air pressure within the pressure sender;
• and
• a second aperture smaller than the first aperture formed in the neck portion below the first aperture and above the lower end of the pressure sender and having a tube downwardly depending therefrom on the exterior of the neck portion to lower the level of urine to below the first aperture when there is no flow into the collector thereby reducing surface tension effects of the urine when it is at the level of the first aperture.
