CCII Based Frequency-Level Characteristics of a Capacitance-Type Liquid Level Sensor<br>

<br>


<strong>Abstract</strong><br>

In this work a capacitance-type liquid level sensor is used to measure level of tap water whose capacitance output is converted to a range of frequencies using second generation current conveyor (CCII) interface. For a liquid level of range 30mm to 130mm the frequency range obtained is 98.3kHz to 81.3kHz. The result obtained in this paper is purely experiment based results.
