Groundwater is constantly in motion. Developed by PHREALOG, the
Groundwater-Flow-Visualization-System was designed to meet the growing standards of groundwater evaluation at comparatively low and efficient price-performance ratio. For the first time, the GFV System allows continuous monitoring of groundwater flow velocity and direction of flow within single wells. As artificial flow markers
are not used the GFV System can be applied without official permission and allows thus to keep down costs. |
