The example electromagnetic transducer may include at least one permanent magnet, a first armature mounted in magnetic cooperation with the permanent magnet, and a second armature mounted in magnetic cooperation with the permanent magnet. The first and the second armatures are arranged to interact with a third armature in magnetic cooperation with the first armature and the second armature. The example electromagnetic transducer may also include at least one electric coil mounted in cooperation with the magnetic field so that electric current through the electric coil to vary the vibratory forces. The example electromagnetic transducer may include an electronic module to control electric current and vibratory forces on a vibrating element of the fluid parameter meter.
