ON/OFF mass flow at an inlet boundary condition

Can any one help me in defining an on/off mass flow rate for a "mass flow inlet" boundary? Please.
Need to allow a mass flow rate example to pause (or off) every x seconds and then flow (or on) every x seconds.
A simple solution please.

I think it can be done with udf; read udf manual, section DEFINE_PROFILE; write a mass flow function of time using if sentences, for example if time >0 && time <5 than mass flow rate =10; elseif time >=5 && time <10 than mass flow rate =0; else mass flow rate=10
Or if you cannot write the udf you can simply stop the simulation and manually change mass flow rate values
