Metalex Liquid level glass in ductile steel which meets the strictest requirements on inductrial and marine refrigeration installations. The liquid level glass are offered in 2 diffrent versions

• With welding nipples ( LGX )
• With stop valves equipped with caps ( LGX SV )

The range of liquid level glasses is based on 3 basic liquid level glasses :

• LGX 185
• LGX 335
• LGX 740

LGX produce sufficient flow areas to secure the highest possible degree of synchonous operation, and have a specially hardened reflection glass for quick reading. The front and base frame are mounted together from the front with countersunk allen screws. This ensures easy installation on site as well as easy inspection and service, if any.

All liquid level glasses are equipped as standard with a built in safety system ( non return device). If a glass is damaged , the pressure of the refrigerant will activate the system and refrigerant loss will be limited to an absolute minimum.
