WebbThe potentiometric map also provides clues about the rate of groundwater flow. If you think back to Darcy material and our in-class activity from last week, you will recall that groundwater flow rate depends on the head gradient (i.e. the hydraulic gradient) and hydraulic conductivity. WebbThe potentiometric surface is an imaginary surface above the aquifer, to which water from an artesian aquifer would rise in a pipe. The term potentiometric surface means head- or potential-indicating surface and … WebbOverview. The OPTISENS PH 8300 is a pH sensor for industrial or municipal wastewater, surface or process water applications. The glass sensor is equipped with a dirt-repellent PTFE diaphragm, making it particularly suitable for harsh applications. It is available with optional integrated Pt100 for temperature compensation. curating process meaning
