Instruction manual 973 SmartRadar LT Page 7
Figure 1.1 973 SmartRadar LT configuration
In the 973 SmartRadar LT the microwave signal is generated and led, via the tank separator, to the antenna
(refer to figure 1.1).
The radar antenna shapes the beam and sends the signal into the tank. The microwave signal reflected
from the product is then received by the same radar antenna. The digital electronics in the SmartRadar LT
measure both the transmitted and the reflected signal.
After processing, the measured distance is converted into level data (innage or ullage) and made available
for field communication.
1.2 Configurations
The 973 SmartRadar LT is installed on the tank separator device.
The antenna is coupled to the 973 SmartRadar LT via the tank separator device. The tank separator
provides for adequate isolation between the tank contents and the electronics in the SmartRadar LT.
Refer to figure 1.1.
Depending on the application, different antennas and tank separators are to be used. The tank separator
adapts the different type of antennas.

For radar level measurement, tanks can be divided
into 3 groups:
• Fixed-roof tanks; free space measurement
• Tanks with a stilling well (fixed-roof and floating-
roof tank); stilling well measurement
• Spheres (high pressure applications); stilling
well measurement
Figure 1.2 gives an overview of the installation on the
different tank types.
