Product Description
1 Product Description
The LoopRadar transmitter uses a non-contact level gauging measurement tech-
nique based on the principle of pulsed microwaves. It is loop-powered and easy
to install and can be used for many types of level measurement applications. The
LoopRadar is safe for humans and has no environmental impact. Propagation of
microwaves is virtually unaffected by temperature, pressure or gas characteristics
in the tank resulting in excellent measurement stability.
1.1 Features
Loop-Power
The LoopRadar only needs one two-wire line for both power supply and output
signal. The LoopRadar is powered by a PLC or a power supply unit.
Communication
The LoopRadar has a 4-20 mA current output and a HART protocol interface for
digital data transmission. The transmitter can be configured by using a HART
communicator (Device Descriptor in preparation), a PC-based setup software or
the Display Panel.

Volume calculation function
A calculation function transforms the measured level into the corresponding prod-
uct volume. The volume calculation is based on one of the standard tank shapes
Sphere, Vertical cylinder or Horizontal cylinder. The LoopRadar also offers the
possibility to calculate the product volume for an arbitrary tank shape by specifying
a Tank Capacity Table consisting of up to 20 levels and corresponding volumes.
