Vessel characteristics

2.3.1

In-tank obstructions

The transmitter should be mounted so that objects such as heating coils, ladders, and agitators are not in
the radar signal path. These objects may cause false echoes resulting in reduced measurement
performance. However, the transmitter has built-in functions designed to reduce the influence from
disturbing objects where such objects cannot be totally avoided.
Vertical and inclined structures cause minimal effect since the radar signal is scattered rather than
directed back to the antenna.
2.3.2

Tank shape

The shape of the tank bottom affects the measurement signal when the product surface is close to the
tank bottom. The transmitter has built-in functions which optimize measurement performance for
various bottom shapes.

Application examples

The Rosemount 5408 and 5408:SIS are ideal for level measurements over a broad range of liquid and
solids applications. The transmitters are virtually unaffected by changing density, temperature, pressure,
media dielectric, pH, and viscosity. Non-contacting radar level is ideal for harsh conditions such as
corrosive and sticky media, or when internal tank obstructions are a limiting factor.
Storage and buffer tanks
The Rosemount 5408 provides accurate and reliable level measurement for both metallic or non-metallic
vessels containing almost any liquid (e.g. oil, gas condensate, water, chemicals).
Reactors
The Rosemount 5408 is ideal for the most challenging applications, including reactors where there can
be agitation, foaming, condensation as well as high temperatures and pressures.
