As per the general practice level instrument nozzles are located away from the turbulence at the liquid outlet nozzle. Although the vessel is provided with a vortex breaker, instrument should be set in the quiet zone of the vessel for example on the opposite side of the weir or baffle or near the vapor outlet end.

While locating the level instrument nozzles on the vertical or horizontal vessels, accessibility and visibility are the two important criteria. At higher elevation, it should be provided with permanent platform or ladder access as specified in the piping design basis.
