Guided Wave Radar Level (Interface) Transmitter

GWLF guided wave radar level (interface) transmitter is a new kind of level (interface) measuring instrument¡«which can be used for measuring level or interface with 4~20mA standard current signal output. The measuring accuracy is not affected by changes of specific gravity and dielectric constant of medium (in the setting range). It features itself with easy operation and simple maintenance. It just needs to input configuration data into the instrument in stead of changing the liquid level on site.

GWLF is designed for complicate and tough working conditions. Radar signals travel along guided wave rod(s) (or cable(s)), instead of through air, so the output of measuring accuracy is stable. The measuring performance cannot be affected by condensate on the rod. The lowest dielectric constant of the medium can be 1.4 (such as 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.
