FIELD: municipal and industrial water supply systems. SUBSTANCE: pipeline accommodates water discharge metering device that has flow velocity transducer incorporating full-pressure line in the form of pressure tube, static-pressure line, sensing element in the form of baffle, two electromagnetic valves, two microswitches, and secondary instrument. Distance between microswitches gages full travel of sensing element that moves at speed of flow. Leading and trailing edges of information signals are periodically shaped at moments of microswitches operation under the action of sensing elements. Instant discharge is determined by length of each of information signals. Device may optionally have one electromagnet with rack-type transmission of linear displacement to cores of slide valves. EFFECT: improved reliability of metering water discharge. 3 cl, 3 dwg
