Summary:This paper deals with the development of a liquid measuring instrumentation using the popular tetrapolar electrode configuration. The system consists of four-electrode ring shape using Cromium metal plate and a small measurement. The developed instrument is calibrated with the help of prepared saline solution prepared in lab. A liquid of known parameter is placed inside the measurement cell and current is injected through excitation electrode with certain frequency and voltage drop is measured across electrode potential terminals. From this voltages and cell constant value, the conductivity, resistivity and impedance of the measured liquid could be determined with acceptable accuracy with more than 96 % compared to the standard measurement.
