JERGUSON^® MAGNICATOR^® II LIQUID LEVEL INDICATOR

THE MAGNET MATTERS

MODEL: JERG_MAGII_LLI

The unique design of the Clark-Reliance^® Magnicator^® II uses two 360º annular Alnico 8 ring magnets with opposing north poles. The force deflection creates a field stronger than any other float magnet arrangement, greater than 90 gauss at the centerline of indicator flags. Physics has guaranteed that the Magnicator^® float has the strongest magnetic field which translates to the most reliable instrument available. Your demanding applications deserve a gage with the guts to stick it out for a long, long time. In addition to conforming to ASME B31.1 for power piping and ASME B31.3 for process piping, all Magnicator^® Magnetic Level Indicators incorporate additional design and construction benefits you will not find on any comparable product.

Features

STANDARD SCHEDULE 40 CHAMBER CONSTRUCTION

Most other magnetic level indicators are offered as Sch 10, with an upgrade to Sch 40 available. Since most plants prohibit Sch 10 pipe, this can be misleading. The difference between Sch 10 and Sch 40 is substantial, with a lower pressure rating and a much greater chance of damage during shipping, handling and construction. We offer Sch 80 and Sch 160 chambers for higher pressures.

SMOOTH AUTOGENOUS WELDS

All standard cylindrical Magnicator^® floats have full penetration autogenous welds. This means an orbital welding machine has fusion-welded the two halves using only heat and no filler metal. This process produces an ultra-smooth weld, without a bead which could interfere with the float’s motion.

OVERSIZED CHAMBER FOR SEVERE/DIRTY SERVICE

Ideal for applications where suspended solids can build up and cause ﬂoat to become “stuck”.
Oversized chamber with guide rods creates free space for ﬂoat to move freely without binding against chamber wall
Free Space allows gage to be ﬂushed without removing ﬂoat, reducing downtime and cost of replacing gasket

HERMETICALLY-SEALED FLAG INDICATOR

Ideal for offshore, corrosive vapors, cryogenic and other severe environments
Permanently sealed, no gaskets or valves; can’t leak or fog
Includes 316SS housing and scale, dual scale available
Flag indicators are purged with inert gas and permanently sealed in polycarbonate tubing with epoxy-sealed end plugs to 500˚F (260˚C) process temperatures; or glass tubing with 100% fused glass end seals to 1000˚F (538˚C) process temperatures.

NIGHTSTAR^® LED ILLUMINATORS

NightStar^® Indicators for the Magnicator^® II make a level indicator continuously visible night or day with bright LED illumination. NightStar^®Illuminators provide an array of bright LEDs to shine on standard mechanical flag indicators the operator can easily and reliably verify level.
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
Can be field-upgraded on any Jerguson^® magnetic indicator, or other manufacturer’s indicator, by replacing both the float and indicator.

Client Feedback

Great team of professionals and they know the valve business. I purchase all my valves from Crume now and would recommend them to anyone.

John Pickett, Driller, Blue Water Drilling

Had a pressure regulator blow at 6am on a Saturday morning. By 10am Crume solved the problem. Can’t beat the service.

Ed, Site Manager, Desert Rat Gas Co.

On extremely short notice, Crume built custom sight glass and gauge cock assemblies that were 12 feet in length. Fit perfectly the first time and ahead of schedule.
