Deep well level sensor of TDR principle

The utility model discloses a deep well level sensor of TDR principle. The axle arrangement is managed along the pump head to two heart yearns from the water pump to ground, whole two heart yearns of root cover is in main anti -interference sheath by stainless steel flexible hose and joint, and ground is placed in to the TDR measuring apparatu, and the TDR measuring apparatu is connected with the upper end of two heart yearns, and outside two heart yearn lower extremes stretched out anti -interference sheath lower extreme, the zero line of pump variable frequency ware need be connected to the stainless steel flexible hose of well head department. The utility model discloses anti converter interference ability reinforce can be realized the dynamic water level of high accuracy and measure, and keep in repair the change and all compare the convenience, is particularly useful for in the deep well that has the work of frequency conversion water pump. 本实用新型公开了种TDR原理的深井水位传感器。两芯线从水泵到地面沿水泵扬程管轴向布置，整根两芯线套在主要由不锈钢软管和接头组成的
