AC-series API conductivity cell

ISO 13503-5, API 61 & 19D


The conductivity cell is constructed in accordance with ISO 13503-5, as well as API RP 61 & 19D guidelines. The cell primarily consists of width slats, platens, and slabs made from Ohio sandstone. It features three pressure taps for tracking longitudinal pressure variations throughout the proppant pack. Electric cartridges heat the steel platens to maintain isothermal conditions, with temperature regulation controlled through a dedicated port by an onboard thermocouple. Additionally, thermal insulation is provided. To gauge the proppant pack's width under varying closure stresses, four LVDTs (Linear Variable Differential Transformers) are positioned on each side of the API conductivity cell.
