ABSTRACT:
Manometer apparatus includes an elongated rigid channel-like frame for protectively enclosing a manometer tube. The frame is formed with a plurality of internal longitudinal slides for supporting a planar or curved scale, a scale adjust slider and a transparent front plate which enables the same frame to be used in a variety of different manometer configurations. The frame may be used in conjunction with a well adjustably mounted relative to the frame and a fluid connection is established between the tube enclosed within the frame and the interior of the well by an accessible small-volume fluid conduit. Several different manometer versions using the same basic frame are disclosed.
