Claim Text:
1. A uroflow meter comprising a beaker ( 4 ), a solenoid valve ( 11 ) and electronic processor ( 6 ) with relay and control circuitry, and a mechanical flow regulating valve ( 14 ) that is placed on a flushing tube ( 12 ) that connects a flush tank ( 13 ) and the funnel ( 3 ) to receive urine, the urine received in said funnel ( 3 ) being emptied into said beaker ( 4 ), and said solenoid valve ( 11 ) being connected to said mechanical regulating valve ( 14 ), characterized in that said beaker ( 4 ) is provided with an arrangement to receive urine from the cistern of a typical urinal, and also a siphoning device in the form of a tube; one end of the siphon tube ( 8 ) being connected to said beaker ( 4 ) at the lower end of said beaker ( 4 ), and the other end of said siphon tube ( 8 ) positioned to release the contents of the beaker ( 4 ) into a drainage system; said siphon tube ( 8 ) securely positioned such that the top tip of the siphon tube ( 8 ) is at such height that the volume of the beaker at that level is more than 1000 ml and that any part of it does not touch any part of the drainage system; further characterized in that a weight sensing sensor is connected to said beaker ( 4 ) and also to an analog-to-digital converter such that when urination begins into the beaker ( 4 ), said weight sensing sensor sends a signal to said converter which calculates the rate of urination, and said weight sensing sensor senses stoppage of urine voiding, sends a signal to the electronic processor which in turn operates the solenoid valve after predetermined period of time for flushing the urinal.
