PMS5003/PMS7003 specs Query

Hi everyone, I am developer and develop embedded devices, I am new on PMS air particle counter sensor i.e. PMS series. Data sheets are well develop but i dont find flow rate of these sensors. However there is no information given about the data PMS sensors givve is cumulative data or differential data.

Hi, I am not sure about what sensors do you refer to, maybe you can share some reference links about these sensors.
