Interchangeable directional differential pressure detector

A system comprising:

• a differential pressure indication device for indicating a presence of a directional differential pressure between a first space and a second space separated from the first space by a barrier, comprising:
• a mount,
• a conduit portion in fluidic connection with the first space and the second space, wherein the conduit portion is connected to the mount, and
• a movable element disposed within the conduit portion and movable from a first, vertically lower region of the conduit portion to a second, vertically higher region of the conduit portion in response to the directional differential pressure between the first space and the second space being greater than a threshold differential pressure;
• and
• a mounting device for mounting the differential pressure indication device to the barrier, comprising:
• a base configured to be mounted against the barrier, wherein the base includes a receptacle in which the mount is removably disposed,
• at least one mounting fastener configured to removably secure the mount within the receptacle,
• a pitch adjuster configured to secure the base to the barrier, wherein movement of the pitch adjuster is configured to adjust a spacing between a portion of the base and the barrier to adjust a pitch of the base,
• a pitch indicator disposed on the base and configured to indicate an orientation of the base with respect to pitch, and
• a roll indicator disposed on the base and configured to indicate an orientation of the base with respect to roll.

A differential pressure indication device for indicating a presence of a directional differential pressure between a first space and a second space separated from the first space by a barrier, the device comprising:

• a mount configured to be mounted to the barrier;
• a pitch adjuster configured to secure the mount to the barrier, wherein movement of the pitch adjuster is configured to adjust a spacing between a portion of the mount and the barrier to adjust a pitch of the mount;
• a conduit portion in fluidic connection with the first space and the second space, wherein the conduit portion is connected to the mount;
• and
• a movable element disposed within the conduit portion and movable from a first, vertically lower region of the conduit portion to a second, vertically higher region of the conduit portion in response to the directional differential pressure between the first space and the second space being greater than a threshold differential pressure.

A differential pressure indication device for indicating a presence of a directional differential pressure between a first space and a second space separated from the first space by a barrier, the device comprising:

• a mount configured to be mounted to the barrier, wherein the mount includes a receptacle and a passageway;
• a conduit portion in fluidic connection with the first space and the second space, wherein the conduit portion is received in the receptacle to connect the conduit portion to the mount, wherein the passageway is configured to fluidically connect the conduit portion to the second space, and wherein the passageway receives at least a portion of the conduit portion;
• and
• a movable element disposed within the conduit portion and movable from a first, vertically lower region of the conduit portion to a second, vertically higher region of the conduit portion in response to the directional differential pressure between the first space and the second space being greater than a threshold differential pressure.
