Transmitter Overview
Blenders and mixers
The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy
to install and commission, it is also unaffected by virtually any fluid property change.
Open atmospheric applications
The Rosemount 5408 measures reliably in open applications, from short range sumps or
ponds to long range dams.
Still pipe and chamber installations
The Rosemount 5408 is an excellent choice for level measurement in tanks with still pipes.
It may also be used in chambers, but guided wave radar is generally the best fit for these
applications. See Section 3.3.8 for installation guidelines.
