SERIES 20 REFLEX AND TRANSPARENT GAGES

HOME / PRODUCTS / CLARK-RELIANCE / LIQUID LEVEL / 20 REFLEX/TRANSPARENT GAGES

JERGUSON® SERIES 20 REFLEX AND TRANSPARENT LIQUID LEVEL GAGES

REFLEX AND TRANSPARENT GAGES FOR PRESSURES UP TO 3270 PSI @ 100°F

REFLEX MODEL: JER_R-20_G
TRANSPARENT MODEL: JER_T-20_G

The Jerguson® Series 20 liquid level gage is the most commonly specified gage and will cover 80-85% of all applications. Important features include a standard recessed gasket surface and shrouded covers. A recessed gasket surface provides positive location of the seal gasket during both assembly and field repair and makes it possible to repair a Jerguson® gage while mounted to the vessel. This design contains the gasket helping to prevent lateral movement which could lead to gasket blow-out (as with competitive gages). For increased visible range, non-shrouded covers and ASTM grade bolting, look at the Jerguson® series 300L reflex and transparent gages.
