DEVICE DETERMINING DIRECTION OF FLOW OF UNDERGROUND WATERS Russian patent published in 1997 - IPC

Abstract RU 2084931 C1

FIELD: hydrogeological investigations. SUBSTANCE: device has vane and sealed chamber of nonmagnetic material attached to it. Chamber houses magnetic pointer. Pointer is bonded to opaque disc having transparent window in the form of ring which width grows proportionally to angular coordinate counted from north tip of pointer. Light source and photodetector optical contact between which is executed through window are positioned on both sides of disc. Signal generated by photodetector is proportional to magnetic azimuth of flow. EFFECT: improved functional reliability of proposed device. 4 dwg
