Abstract
The invention is a method and a device for measuring the filtering or purifying capacity of a purifier. The invention allows the use of a single analyzer for sampling the inlet and outlet streams. This is accomplished by sampling the inlet stream only at some times when the change in the inlet stream is expected to occur. At other times the outlet stream is sampled to monitor its composition. A computer system on the basis of the accumulated data decides when it is time to replace or to regenerate the purifier or the filter bed. The computer system also determines the strategy of when to sample the inlet stream. Various system sensors may be used to make this determination, such as pressure sensors and level sensors. The data from other sensors, such as flow sensors, may be used in the calculations performed by the computer system.
