ABSTRACT:
A system for monitoring the condition of impulse lines to a differential pressure sensor. The lines may be connected at two locations of a pressure source, such as a pipe having a fluid flow. One line may direct a pressure of the source to one side of a piezoelectric diaphragm and another line may direct another pressure to the other side of the piezoelectric diaphragm. The diaphragm may provide an electrical indication of the differential pressure between both sides of the diaphragm. One of the lines may also be connected to a piezoelectric diaphragm of a static pressure sensor. The latter diaphragm may provide an electrical indication of static pressure. Detection and comparison of noise levels of the electrical indications of the pressures may indicate if one or both lines are plugged, and which one if not both.
