Switching configuration for electronic recognition of opening and closing of taps in piping system, has evaluation circuits that recognize closing of tap based on signals from comparators, and which then allocate signals

摘要

A pressure signal (4) from a pressure sensor (3) is input into a differentiation circuit (5) that outputs a differentiated pressure signal (6) that is input into comparators (7,8). Each comparator outputs a signal (9,11) to evaluation circuits (10,12) which recognize the closing of a tap and allocate signals (13,14).
