| Summary: | This paper proposed an alternative method of
measuring water level using a Printed Circuit Board(PCB). The
design of the electrode water level sensor went through circuit
sketching, printing of sketch on PCB and etching. The signal
conditioning circuit board was fabricated using a donut board
and other electrical components. Experimentation was carried
on the fabricated electrode sensor and the capacitance and
current for each electrode finger was measured using digital
multimeter and LCR meter. The multiple correlation of the
water level, measured current and measured capacitance
produced a value of 0.921 with P-values less than 0.05 showing
the strength of the data obtained from the test conducted. The
electrode water level sensor has proven to be consistent and
reliable under normal working condition. |
