Abstract
A monitoring system (10) is disclosed for monitoring the condition of a filter (16) filtering a gas or liquid. Using various sensors, the permeability of the filter is monitored on a continuous basis. A significant increase in permeability, decrease in permeability or rate of change of permeability can lead to an indication of filter failure, such as rupture, leakage, loading and unloading. The system can be monitored by a computer and monitored from a remote location through phone lines and Internet computer systems.
