Jerguson Magnicator Magnetic Level Indicator

A sealed float with a permanent magnet rises and falls in a chamber with the process level. An external indicator, isolated from the fluid, shows the level through rotating flags. It reduces leak paths compared with sight glasses.

Jerguson FlashProof Magnicator

A larger 3-inch chamber with internal guide rods lets trapped gases escape, reducing errors from boiling or flashing fluids. The chamber also resists binding from dirt, sludge, or waxy solids and can be flushed without removing the float.

Magnicator with Guided Wave Radar (MGWR)

This design combines a magnetic level gage with a guided wave radar transmitter on one set of process taps, giving two independent level readings for redundancy. The radar reading remains accurate if the float fails and across varying product density.

NightStar LED Illuminators

LED lighting makes magnetic level indicators visible day or night, improving visibility and reducing time spent in process areas. The illuminators are approved for Class I, Div. 1 locations.

• High contrast indication
• Not angle dependent – viewer can see clearly from many positions
• Reduced operator exposure in process areas can increase safety
• LEDs have a nominal life of 10 years
• Approved for use in Class I, Div. 1 classified locations
• FL Series Standard Flag
