1. Armored Glass Level Gages

JJerguson® reflex level gages are ideal for clean total level indication applications for refining, petrochemical and general use applications.
Jerguson® transparent level gages are selected for interface level indication, dirty service or any application that requires the use of a shield to protect the glass from corrosion.

2. Magnetic Level Gauges & Accessories

Magnetic level gauges may be used for applications where a level gauge glass may be unsafe, an environmental risk or to increase the visibility of the level indication. High pressures, high and low temperatures, toxic and corrosive services can be risky applications for level gauge glasses. Some chemical services can attack the glass material causing breakage or discoloration Liquid-liquid Interfaces can be very difficult to read in a gauge glass. Magnetic level gauges can also be fitted with level switches and transmitters.

3. Gage Glass Illuminators & Accessories

To improve the readability of flat glass liquid level gages in poorly lighted areas. Jerguson® Gage Illuminators incorporate the principle of wedge lighting which gives a bright, evenly diffused light, free of glare or blinding areas over the entire length of the gage glass.

4. Guided Wave Radar

JERGUSON® is pleased to offer the Model MGWR for the Magnicator II® Level Indicator. The MGWR provides redundant level measurement through the combined use of the reliable Jerguson Magnicator II level gage and an independent Guided Wave Radar level transmitter. The guided wave radar transmitter provides an independent level measurement that is not density dependent, resulting in true redundant technology.
