GWLF Guided Wave Radar Level Transmitter
General
GWLF Guided Wave Radar Level 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 configuration 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.
For the top mounted, types
of transmitting head and
probe,
length
of
neck
(stand-off pipe) should be
provided
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.
For GWLF with measuring
cage, please provide types
of transmitter, probe and
measuring cage.
