Grid ruler (402) is constituted, and wherein ruler (401) is close to be loaded on transparent cylinder (310) lateral surface, can manually read pit shaft (301) liquid Position, and grating scale (402) is made of scale grating (403) and grating reading head (404), scale grating (403) is fixed on It is corresponding with grating reading head (404) being fixed on water tank (205) outer wall side on the inner surface of frame (8) left back column, To measure the exact value of the displacement of water tank (205) lifting travel and calibrating liquid level；The control system (9) be by computer (901), PLC (902) is constituted, and wherein computer (901) controls motor lead screw transmission group (203), adjustable speed water pump through PLC (902) respectively (102), motor-driven valve (101), electric T-shaped valve (305) realize lifting, water supply and the return water of water tank (205), guarantee water tank (205) liquid level is consistent with two sides pit shaft (301) interior level balance, and computer (901) acquires grating reading head through PLC (902) (404) scale grating (403) signal in water tank (205) lifting moving, measurement water tank (205) go up and down relative displacement, adjust Water tank (205) lifting position guarantees that the liquid level of liquid level meter detecting device respectively corresponds every liquidometer zero of different type, range Point position, and the relative displacement measurement data of each liquidometer zero point and detection liquid level point is stored in computer (901), it is arranged Middle minimum liquid level meter zero point is that water tank (205) detect initial position, examines and determine the relative displacement of point with each liquidometer to adjust liquid level The calibrating liquid level of calibrating installation is counted, realizes that water tank (205) complete whole calibrating points of all liquidometers in a lifting process Verification process, greatly improve liquidometer detection calibrating efficiency, and camera (201) and two sides camera (213) warp Computer (901) acquires image, observes liquid level kickboard (204), side-mounted liquidometer (5) and roof-mounted liquidometer (6) in real time and exists Liquid level variation in verification process.
