➂
With aluminum housing only. Does not apply to
models with 316 SS transmitter housings.
➃
The displacer must always be completely immersed
in process liquid when the E3 is used in interface or
density service. Top mounted models require liquid
level to exceed the top of the displacer by 2" at all
times to ensure optimal performance.
