Borehole And Water Company Use Geophysical Terrameter By Geologist
Terrameter is included transmitter, transmitting electrode, receiving electrode and receiver, it is usually required that the transmitter, transmitting electrode, receiving electrode and receiver are in a straight line.
The transmitter injects a stable current into the ground through the transmitting electrode, thereby establishing a stable current field underground and on the ground, and the potential of a certain point on the ground sent to the receiver through the receiving electrode.
The potential of a certain point on the ground is sent to the receiver through the receiving electrode, and the receiver measures the potential difference between the two electrodes. The emission current is measured, and the apparent resistivity between the two electrodes is indirectly obtained by using the device coefficient.
