Vibration monitoring instruments for pumps are generally characterised as velocimetric type. Velocimetric type instruments have a measuring range typically in inches/sec or mm/sec. Accelerometric (in inches/sec2 or mm/sec2) or distance-type (typically in microns) vibration readings are usually taken at bearings and shafts of more high-tech equipments like turbines.
