1Rotameter, Bypass

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.
