Abstract
An apparatus for measuring flow in a conduit includes a sensor head configured for insertion transversely through a conduit sidewall to position the sensor head in an electrically conductive fluid flowing through the conduit. The sensor head includes a core and a coil that at least partially surrounds the core, the coil being excitable to generate an electromagnetic field. The sensor head also includes first and second electrodes spaced apart from each other, and a body that supports the coil, core, and electrodes. The body includes at least one channel through which the electrically conductive fluid flows. The electrodes are positioned in the at least one channel. Each channel is defined by opposing sidewalls that have a converging configuration.
