Answer 1

That may depend on your application. The pressure drop will depend on whether you are filtering gas or liquid and whether you are interested in the pressure drop of new filter samples or filters in use as they become clogged. Flow rate will also increase pressure drop.


For example, if the filter is installed at as joint in a round horizontal pipe, and the flow is liquid (water?), and the pressure is relatively low, you can attach vertical plastic tubes with pipe fittings upstream and downstream of the filter. If the water rises say one foot higher in the upstream tube than the downstream tube, the pressure drop across the filter is 12 inches w.g. (water gage). If the pressure is too high for plastic tubes (where about 15 psi would require 34 foot high tubes), you can attach pressure gages to the pipe fittings and compare their readings or install a differential pressure gage across the fittings to directly read the pressure drop.

If the flow is a gas (air?), flowing through a duct, you can install a clear plastic "U" tube partially filled with water (and food coloring?) across fittings upstream and downstream of the filter to measure the pressure drop in inches w.g. or use a sensitive differential pressure gage. Hope that helps a little.
