Abstract
Water-closet system equipped with uroflowmetry analyzer to measure out urine flow rate and volume was developed, to improve the medical treatment environment. This is an experimental study to evaluate the performance of the water-closet system, setting up in drainage stack and horizontal fixture branch piping system. As a result of examinations, allowable measurement accuracy with uroflowmetry and the reliability of system are confirmed quantitatively, under the pipe pressure fluctuations which is given by actual drainage load. The Water-closet system can be available for 2-pipe vertical drainage stacks equipped with loop-vent pipes, under the condition of permissible pipe pressure within ±100Pa.
