Measuring Principle:

A sample of the fuel to be tested is passed at a constant rate of flow (20 mL/min) through a glass fiber filter medium.
The pressure drop across the filter is monitored during the passage of a fixed volume of test fuel.
If a prescribed maximum pressure drop is reached before the total volume of fuel is filtered, the actual volume of fuel filtered at the time of maximum pressure drop is recorded and used to obtain the automatic calculation result.
Otherwise if the prescribe volume is filtered without reach the 105kPa pressure, the maximal pressure during the test is recorded and used to obtain the result.
