FIELD: medical equipment.
SUBSTANCE: sensor can be used for measuring amount of urine during urination. Amount capacitance sensor has metal mug with bottom made of dielectric material. The mug has two plates, each plate is provided with electric output. Side wall of the mug has to be one plate of capacitor and surface of fluid to be measured has to be its second plate. Electric output of the plate is brought into contact with surface of fluid. DC capacitor is mounted between electric outputs of both plates of mentioned capacitor.
EFFECT: improved conditions of operation; better hygiene of process of measurement.
