dear alireza,

It is having a good accuracy comparatively other,
it much depend on your frq. of operation. higher ferq. higher accuracy but lower range of distance measurement. Time constant depends on your sensor choosen normally 4 ms. operating temp -20 to 65 deg C. It will be very cheep( 400 Rs Indian currency) compactness depends on your application and hardware.
bye wish u a best of luck.
