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.
Claims30
Manometer apparatus comprising
- A. an elongated rigid frame
- 1. formed as a channel having a rear wall and a pair of spaced-apart sidewalls, and
- 2. defining an internal scale slide extending substantially the entire length of the frame;
- B. an elongated open-ended manometer tube positioned in the frame;
- C. upper closure means for closing the upper end the frame, said upper closure means including fluid conduit means extending through the closure means and establishing a fluid connection to one end of the tube;
- D. lower closure means closing the lower end of the frame;
- E. means for removeably securing the upper and lower closure means to the upper and lower ends of the frame;
- F. an elongated, card-like scale, said scale being
- 1. somewhat shorter than the frame, and
- 2. slideably mounted in said scale slide for lengthwise movement therein;
- and
- G. scale adjusting means releasably secured to the scale and extending outside of said frame for adjustably positioning the scale lengthwise in the frame relative to the tube.
Manometer apparatus comprising
- A. an elongated rigid frame formed as a channel having a rear wall and a pair of spaced apart sidewalls and having an interior surface defining a plurality of slides including
- (1) a planar scale slide which extends substantially the entire length of the frame,
- (2) a curved scale slide which extends substantially the entire length of the frame,
- (3) a longitudinal scale adjust slide in the rear wall of the frame, and
- (4) a front plate slide in the frame sidewalls extending substantially the entire lengths of those walls;
- B. a manometer tube positioned in the frame;
- C. upper and lower closure means engaged to the upper and lower ends of the frame, said upper closure means including fluid conduit means extending through the upper closure means and establishing a fluid connection to at least one end of the tube;
- and
- D. means for removably securing the closure means to the frame.
