Level Indicator

This liquid level indicator is not only used to measure water level, but if you can measure the level of chemical liquids that are experimentally shown or shown by direct passage. The basis of the circuit work is based on a high frequency oscillator whose output is applied in nature. Constantly changing the direction of the current causes it to change constantly if the current passes, and as a result, if there is an effect during the passage of the current.   DOWNLOAD FILE
