GWLF guided wave radar level (interface) transmitter
General
GWLF guided wave radar level (interface) transmitter is designed and developed
by Dandong Top Electronics Instrument Co., Ltd. GWLF can be used for
measuring level or interface with 4-20mA standard current signal output. The
measuring accuracy is not affected by change of specific gravity and dielectric
constant of medium (in the setting range). It features itself easy operation and
simple maintenance. It only needs to be entered figuration data into the instrument
and it doesn’t need to change the liquid level at field. So, GWLF is a new kind of
level (interface) measuring instrument.
GWLF is designed for complicate and tough working conditions. Radar signals
travel along guided wave rod(s) (or cable(s)), instead of propagating in air, so
measuring accuracy output is stable. The measuring performance cannot be
affected by condensate the on rod. The lowest dielectric constant of the medium
can be 1.4 (Example: butane). Measurement cannot be affected by boiling,
fluctuation, turbulence, even mixer in the medium. Measuring data have nothing to
do with changes of working conditions (process temperature, process pressure,
specific gravity of medium). GWLF can trace the liquid level quickly.

Application
Medium: Any liquid, slurry or powder material with dielectric constant
between1.4-100
Vessel: Almost all processing vessels, tanks and bypass containers within the
allowed range of temperature and pressure for probe.
Conditions: GWLF can be workable under the different tough working conditions
such as volatile liquids, liquids with foam, sticky liquids, liquids with fluctuation,
bubbling or boiling liquids, frequently loading and unloading, variable dielectric
constant or specific gravity, etc.

Performance
Two-wire, DC 24V supply power, low power consumption, optional HART
protocol.
Performances cannot be affected with change of specific gravity, dielectric
constant, and other change of working conditions.
For twin-rod probes, measurement cannot be affected by a little quantity of
medium stuck with probes. And the instrument can still keep high measuring
accuracy.
With universal coupling, orientation of transmitter can be adjusted to any

Three keys for configuration, LCD for values indication.
Housing with 45
structural angle is convenient for wiring and installation.
The length of rigid probe is from 0.6 to 6.1m. The length of cable probe can be up to 21m.
The connection between transmitting head and probe is interchangeable. Transmitter can be
disassembled off simply by screwing off the nut between transmitter and probe.
