Description
Based on Faraday’s law of electromagnetic induction, this product has no moving parts, offering high measurement accuracy, a wide range, fast response, and immunity to the temperature, pressure, and viscosity of the measured liquid.
In hydrogeological exploration pumping (or injection) tests — whether single-layer or multi-layer mixed pumping/injection tests — it can be combined with flow logging to provide the depth and thickness of all aquifers and the inflow (or absorption) rate of each aquifer, obtaining definitive data on whether complementary relationships exist among aquifers under natural static water level conditions.
It can also check whether the borehole casing seal is tight and provide leakage flow data for poorly sealed sections. In addition, it can determine whether there is inflow (or absorption) at the borehole bottom.
