Abstract: A diaphragm metering pump (20) has an electromagnetic drive comprising a coil (28) and a movable armature (30). A shaft (40) connects the drive to the diaphragm (46). The electronic control consists of a pulser circuit (64) with the microprocessor (68). A position sensor (60) senses the position of the armature to determine the stroke length and 2 pressure transducers are sensing the differential between diaphragm (46) pressure and discharge pressure. The output of the sensors is processed in the microprocessor to apply half-wave rectified pulses to the coil according to the software checking sensor data against the calculated values for the maximum stroke length, rate and pressure. The power to the coil can be adjusted by phase control. Therefore the power consumption and the generation of heat in the armature area can be reduced.
