The utility model provides a pumped well moves water level measurement device, including electric survey line, the detection unit with be used for the spooler of the fixed electric survey line of winding, the cover is equipped with measuring catheter on the electric survey line, and the detection unit includes probe and signal lamp more than 2, and the probe comprises insulating heavy object, insulating baffle and two electrodes, and insulating heavy object is fixed in the sense terminal of electric survey line, two electrode symmetries distribute in the bottom of insulating heavy object and connect electric survey line, insulating baffle lies in between two electrodes, each signal lamp through electric survey line respectively with each to electrode series connection, the utility model discloses a multilayer probes structure, each signal lamp through electric survey line respectively with the electrode series connection of each probe, explain then when the scintillation appears in the signal lamp that the current surface of water is undulant great, the survey line that discharges under then can continuing, until all signal lamp chang liang, then pop one's head in in the top highly is the pumped well water level promptly, measuring catheter guarantees that electric survey line and probe receive and release smoothly, and measuring catheter plays the effect of stabilizing intraductal liquid level simultaneously.
