This is totally depending to WHAT KIND of analysis you are referring to. They could be of equal or of totally different value for one or another compound. Potentiometry is based on acid/base reactions and pH change at equivalence point, while conductometry is based in change of the (conductivity) behaviour of ions, also applicable to redox, precipitometric (argentometric) AND acid/base reactions.
The common laboratory conductivity meters employ a potentiometric method and four electrodes. Often, the electrodes are cylindrical and arranged concentrically. The electrodes are usually made of platinum metal. An alternating current is applied to the outer pair of the electrodes. The potential between the inner pair is measured. Conductivity could in principle be determined using the distance between the electrodes and their surface area using the Ohm's law but generally, for accuracy, a calibration is employed using electrolytes of well-known conductivity. Industrial conductivity probes often employ an inductive method, which has the advantage that the fluid does not wet the electrical parts of the sensor. Here, two inductively-coupled coils are used. One is the driving coil producing a magnetic field and it is supplied with accurately-known voltage. The other forms a secondary coil of a transformer. The liquid passing through a channel in the sensor forms one turn in the secondary winding of the transformer. The induced current is the output of the sensor.

auntitatve analysis applied for all reactions such(redox reaction....precepitating reaction...acidic reactions...complexmetry reaction)
