Abstract: There is disclosed an antistatic capacitance probe including an electrically conductive gland for receipt in a port formed in the wall of a vessel for receiving a flowable material. A tubular central conductor projects axially from the gland and into the vessel and has its projecting extremity encapsulated in a dielectric insulator. An equalizer conductor wire is connected on one end to the gland and is spiral wound around the insulator throughout its length and is in electrical contact with such insulator to thus remove any static charge therefrom and conduct it into the gland, thus preventing static charge buildup on such insulator.
