The invention provides a glass liquid level meter. The glass liquid level meter comprises a base used for being fixed to a user field mounting base, a stand column used for being matched with the baseto form a supporting frame, a controller used for recording and transmitting signals, a single-axis
robot used for controlling a probe to move up and down, and a
servo driver used for controlling thesingle-axis
robot. The stand column is vertically arranged above the base, the controller is arranged on the stand column and located at the end close to the base, the single-axis
robot is arranged on the stand column and located on the side adjacent to the controller, and the
servo driver is arranged on the stand column and located on the side opposite to the single-axis robot. The
integrated design is adopted, the structure is compact, maintenance is convenient, the production cost is effectively reduced, and the reliability of the device is improved; and moreover, linear guide rail guidingand
ball screw displacement transmission are adopted,
interference fit is adopted, no transmission gap exists, and therefore, high-precision and low-
inertia transmission is achieved, and the
measurement precision of the whole device is guaranteed.
