Abstract (en)
[origin: WO2007136366A2] A calibratable vertical fluid level gauge (2) for displaying a fluid level in an enclosed vessel (1) includes a float portion (6) and a gauge portion (4). The float portion (6) is disposed within the enclosed vessel (1) and converts a vertical displacement of a float (10) into a rotational displacement of a first rotating member (26). The gauge portion (4) is disposed on an exterior of the enclosed vessel (1) and includes a second rotating member (34), a pointer (38), and a clutch mechanism (42). The gauge portion (4) is arranged with respect to the float portion (6) such that the second rotating member (34) is rotatably coupled to the first rotating member (26). The clutch mechanism (42) selectively engages the pointer (38) to the second rotating member (34) and disengages the pointer (38) from the second rotating member (34) to allow movement of the pointer (38) with respect to the second rotating member (34) to calibrate the gauge (2).
