In this study, the planning and implementation of measuring a liquid level with the help of a remote grounded capacitive sensor is described. The electrodes of a capacitive sensor are made up of low-cost materials mainly an insulated wire (PTFE) and a stainless-steel rod. A primary relaxation oscillator and a microcontroller are used in the interface circuit. The sensor is connected to the interface circuit by an actively protected wire. The active-shielding circuit's stability is surveyed by thinking about the parasitic parts of an interconnecting link and the sensor. The device was tested by recording how much tap water was used in a grounded steel container. Now, when the level range is about 70cm, the system has an error smaller than 0.34mm and a 0.09mm resolution for measuring the time of around 19ms.
