[Problem to be Solved]

The present invention provides a system which can detect/check an underground water vein in a specific ground area and detect/check underground water in the underground water vein at a pinpoint.

[Solution]

The present invention has, while two-dimensionally visualizing an underground water vein in a specific ground area, a large number of electrodes group 22 disposed in the specific ground area, a survey point switching unit 23 having two poles in an electrode 22a with four poles in dipole-dipole arrangement in the electrodes group 22 set to potential electrodes, while the other two poles as current electrodes and combining and switching them so as to execute horizontal exploration and underground vertical exploration, measuring means 25 for each survey point of the entire ground area, specific resistance calculating means 31 for each survey point for calculating a specific resistance value at each survey point for each of high and low two frequencies in the horizontal and vertical directions at each survey point of the ground area, and impedance effect is acquired for each survey point on the basis of the calculated specific resistance value for each of the high and low two frequencies at each survey point so that estimation that a survey point position with the impedance effect>1 has an underground water vein can be made and displayed three-dimensionally.

An electro-magnetic induction fluid conductivity sensor is described which includes a hollow non-conductive body defining a fluid chamber. The fluid chamber has a first end and a second end. A voltage transformer is provided which is capable of inducing an electric field into fluid positioned within the fluid chamber, thereby causing an electric current to flow through the fluid. An instrument is provide for measuring the electric current. A conductive shunt receives the electric current induced by the voltage transformer in the liquid at the first end of the sample chamber and returning the electric current to the second end to complete an electrical circuit.
