Abstract:
1. A magnetic flowmeter for measuring a flow of a process fluid, comprising: a flow tube arranged to receive the flow of process fluid therethrough; a first coil arranged adjacent the flow tube; a second coil arranged adjacent the flow tube; a third coil arranged adjacent the flow tube; drive circuitry configured to apply a magnetic field to the process fluid using the first, second and third coils; first and second electrodes arranged to sense an electrical potential of the process fluid related to the applied magnetic field and flow rate of the process fluid; and a controller configured to calculate the flow of the process fluid based upon the electrical potential sensed by the first and the second electrodes; wherein the first and second electrodes are radially offset from the coils such that a line between the first and second electrodes forms an acute angle with a line between any of the first, second and third coils.
