Background- Lube oil filters are used largely in manufacturing industries. These filters are changed once they are chocked/clogged. The intensity of clogging is determined by Pressure difference (DP) before and after the filter. If DP in 1 then filter is to be replaced and DP across new filter is 0.1.
These filters when in operation does have same life every time we replace them. Due to more impurities in line oil these can get clogged at an early stage. Correctly, determining the Rate of Change of filter DP that is the rate at which filter DP is increasing is very crucial for continuous operations.
