What have you tried? Do some research, write your own Linq (this should be easy, it is a simple query). Then, if you still have trouble, post your linq, explain why do you think it doesn't work and someone will help you. Thank you.

You can use by changing. Can't use groupby here
example:
var count =db.STATION_PM.Select(p=>p.ID_PM).Distinct().Count();
