Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-3.

The embodiment is as follows: a portable electric measuring water level gauge for preventing error measurement is shown in figures 1 to 3 and comprises a cable ring plate 1, a steel ruler cable 6 and a probe, wherein one end of the steel ruler cable 6 is wound on the cable ring plate 1, and the other end of the steel ruler cable 6 is connected with the probe; the steel ruler cable 6 is formed by combining a steel ruler and a conducting wire, and the conducting wire and the steel ruler are combined into a whole through a process, so that the steel ruler can be prevented from being rusted, the operation process is simplified, and the measuring and reading of numerical values are more convenient and accurate; the probe comprises a probe shell 3 and a probe 4, the dead weight of the probe shell 3 can keep the steel ruler cable 6 tight in the process of lowering and recovering, and the measurement accuracy is guaranteed. As shown in fig. 2 No. 2, one end of the steel rule cable 6 is inserted into the probe housing 3 and fixed by the probe connector 9; as shown in fig. 2, No. 2 and No. 3, the two probes 4 are copper probes 4, a nylon column 11 is fixedly installed in the probe shell 3, the nylon column 11 is fixedly sleeved on the probes 4, and the copper probes 4 are electrically connected with the steel ruler cable 6 through a connecting terminal 10;
