Description

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 density or dielectric constant of medium (in the setting range). It is easy operating and maintenance. It only needs to be entered configuration data into the instrument and no need to change the liquid level at field. So, GWLF is a new type of level (interface) measuring instrument.
