Apparatus for couplant management

A couplant feeding circuit plate comprising:

• a housing comprising a wall extending circumferentially around a couplant cavity, the couplant cavity defined by the wall and a membrane;
• a couplant port disposed in the wall, the couplant port configured to route couplant to the couplant cavity;
• and
• a vacuum port disposed in the wall, the vacuum port configured to route at least a portion of the couplant from the couplant cavity.

A non-destructive testing (NDT) apparatus comprising:

• a wedge comprising:
• a couplant chamber;
• a vacuum port;
• and
• a couplant port;
• a transducer disposed at a first end of the couplant chamber;
• and
• a couplant feeding circuit plate having a top surface and a bottom surface, the couplant feeding circuit plate top surface being disposed at a second end of the couplant chamber opposite the couplant chamber first end, the couplant feeding circuit plate comprising:
• a housing comprising a wall extending circumferentially around a couplant cavity, the couplant cavity defined by the wall and a membrane;
• a couplant port disposed in the wall, the couplant port configured to route couplant to the couplant cavity, the couplant port being coupled with the wedge couplant port;
• and
• a vacuum port disposed in the wall, the vacuum port configured to route at least a portion of the couplant from the couplant cavity, the vacuum port being coupled with the wedge vacuum port.
