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).
