Transmitter Overview

Reference peak

This peak is caused by the transition between transmitter and the tank vapor space or air. It is
used by the transmitter as a starting reference point for distance to the level surface.

Product surface peak

This peak indicates the product level and is caused by a reflection from the product surface.

Interface peak

This peak indicates the interface level. The peak is caused by reflection from the interface
between an upper product and a bottom product with a relatively high dielectric constant. This
peak is identified when the Measurement Mode is set to Product Level and Interface Level or
Interface Level with Submerged Probe.

Probe end peak

It is caused by reflection from the probe end. If the probe is grounded, the peak will be positive.
If the probe end is submerged in a high dielectric media, such as water, it will not be visible.

Upper reference point

The Upper Reference Point is located at the underside of the transmitter flange or the bottom
end of the threaded adapter, as illustrated in

Figure 2-2 on page 4

.

Figure 2-2. Upper Reference Point

Zero reference point

The Zero Reference Point is selected by the user and is usually located close to or at the bottom
of the tank. The Zero Reference Point can be set to any position in the tank by adjusting the Tank
Height.
