Typically, an optical disdrometer is used.

The multifunction laser optical disdrometer meets the highest requirements. The device works on the quenching principle and measures precipitation particles using the shadow they cause when passing through the laser beam. From the raw data are calculated the amount and intensity of precipitation, visibility in precipitation, the kinetic energy of precipitation and the equivalent of radar reflectivity.

Thanks Pr Bachir Achour for all informations, please, is this material available in Algeria in university laboratories?
