Alternatively, a differential pressure gauge (4) can be used. If the appliance is fitted with a shut off valve, open it fully. Adjust the flow rate by means of the regulating valve (1) installed downstream of the filter. Measure the differential pressure at a range (e.g. 10) of flow rates in order to generate a pressure drop curve (curve A, Figure 5). In order to determine the pressure drop curve for the filter itself, repeat the above procedure with the filter removed (curve B). The filter pressure drop (curve C) is obtained by subtracting curve B from curve A.
