A particular area on the pitch is chosen. Say only 10cm.
And speedometre is put to screen the ball in that 10cm..
As soon as ball crosses that 10cm, its speed is measured. That is how fast the ball covered those 10cms.
After that it is converted into kmph or mph.
Metres are not put over the entire pitch, they just 'focus' only on a small area.
For example, Speed Guns used by traffic cops worldwide to monitor speed of traffic or any particular vehicle. It zooms in only at small part of road, say 1 metre. As soon as any vehicle over shoots speed limit in that 1 metre, it is fined for overspeeding even if that vehicle slows down on spotting cops, isn't it?
Got it.

there are special speed sensors used to collect the data about speed and possible trajectory of the ball. These sensors are put beside the pitch, this is the latest technology otherwise till recent(and still at some places) speed guns were used to calculate the speed. Speed guns operate on the same technoloy as of radars (sonar technology ).

From the time it leaves the bowlers hand to when it touches the surface of the pitch.
