General 
UGS series color quartz glass liquid level gauge is a local display level gauge uses high purity quartz (99.99% SiO2) as material. Main advantages are clear display, great seal performance, high temperature resistant, high pressure resistant, sticky proof, long duration. This product is widely used for all kinds of vessel liquid level measurement in petrol, chemical, power industries. 

UGS-A standard color quartz glass liquid level gauge is suitable for transparent medium, such as water, liquid ammonia, petrol, LNG etc. This type has no blind display area and it is an very common type of local display level gauge. 

UGS-B ordinary standard color quartz glass liquid level gauge are suitable for transparent medium, such as water, liquid ammonia, petrol, LNG etc. This type has hot blind display area. 

UGS-C erosion resistant color quartz glass liquid level gauge is suitable for many acidic and alkaline liquid and some organic solvent. 

UGS-D erosion resistant color quartz glass liquid level gauge is suitable for environment with high erosion medium, high temperature and high level measurement.
