ABSTRACT:
A piping system surveillance apparatus has a CRT for displaying a graphic pattern of a piping system. Detectors are arranged in active construction members such as a valves, and pumps of the piping system so as to directly detect the presence/absence of fluid flow in the active construction members in accordance with operating conditions thereof. The presence/absence information of the fluid flow in non-active construction members is obtained by a CPU in accordance with logic operation of detection signals from the detectors. Data indicating the presence/absence of the fluid flow is compared with data indicating the presence/absence of the fluid flow in the construction members of the piping system in normal operation and is discriminated to be normal/abnormal. This discrimination result and the data indicating the presence/absence of actual fluid flows are displayed by the corresponding display elements of the graphic pattern on the CRT.
