Abstract
A modular meter movement having two or more coil assemblies. One embodiment of the meter is modular and includes coil assemblies that are formed as separate parts and configured to be attached to a magnet housing that houses a rotatably mounted permanent magnet. The magnet housing includes a plurality of arms that can accept either two or three coil assemblies depending upon the embodiment. The coil assemblies are placed over the magnet housing such that the coil assemblies at least partially surround the magnet housing. The magnet housing and coil assemblies are placed within a shield pot formed from a magnetically susceptible material. In one embodiment, the shield pot is non-cylindrical and the axis of rotation of the permanent magnet is mounted off the central axis of the shield pot. The shield pot is shaped so that even though it is non-cylindrical, it does not induce a homing position in the resulting meter.
