    Jerguson Magnicator Flashproof Magnetic Flag Liquid Level Indicators for Boiling Fluids or Flashing Vapors

    The Jerguson FlashProof™ Magnicator design addresses problems that may occur with standard level indicators: boiling fluids, flashing vapors, and problems caused by dirty or viscous services. This design provides an accurate float level and indicator reading, and allows the gage to be flushed without removing the float from the column.

    Jerguson Magnicator WF Series Wide Magnetic Flag Liquid Level Indicators

    Jerguson recommends flag indicators for virtually all applications, therefore flags come as standard on all Magnicator® products. The Magnicator WF series of flag style liquid level indicators are the most reliable, shock resistant, longest lasting magnetic level indicators available, and now they’re also the widest! The Jerguson WF Series wide indicator flags are 1 1/2″ (38.10mm) wide, have single stainless steel stamping, a permanent magnet in each flag, and dual rotation points. At rest, each flag is strongly attracted to each adjacent flag of the same color, with an active magnetic field of 200 Gauss at the leading edges. This attraction can only be broken by a magnetic field strong enough to cause the flags to rotate.

    Jerguson Mini-Magnicator Economical Magnetic Liquid Level Indicator

    The Jerguson Mini-Magnicator provides the same easy to read level indication as the Jerguson Magnicator, in a smaller more economical package. The Mini-Magnicator utilizes the standard Jerguson latching flag design – 316 stainless steel flags with a ceramic magnet for maximum reliability. It is specifically designed for low pressure, light duty applications, and is a great replacement for fragile tubular glass.

    Jerguson SAS-16 Tri-Magnet Magnetic Latching Snap-Action Point Level Switches

    The Jerguson SAS-16 Snap-Action Switch is a switch mechanism based on a unique Jerguson tri-magnet design where the snap action is accomplished by the utilization of magnetic repulsion. The magnet mounted in the float causes the secondary magnet to rotate as it passes up and down. The switch magnet is repelled by the secondary and snaps to the opposite side. This causes the cradle to pivot, moving the push rod which operates the switch contacts. The result is positive snap action interlock switching – no springs, no cams, no problems.

    Jerguson Series 20 Liquid Level Gages, Reflex R-20 and Transparent T-20, Armored Flat Glass Gages

    The Jerguson Series 20 liquid level gage is the most commonly produced covering 80-85% of the applications encountered. The Series 20 armored glass gage features a recessed gasket surface, and shrouded covers. A recessed gasket surface provides positive location of the seal gasket during both assembly and field repair. This makes it possible to repair the gage while mounted to the vessel. The recessed gasket surface contains the gasket to prevent lateral movement which could lead to a gasket blow-out (as with competitive gages). All Jerguson armored glass gages are hydrostatically tested at 1 1/2 times the design pressure rating at 100°F (38°C) prior to shipment.

    Jerguson Series 300L Liquid Level Gages, Reflex R-300L and Transparent T-300L, Armored Flat Glass Gages, ANSI 300

    The Jerguson Series 300L liquid level gages are lower cost with increased visible ranges. The series 300L provides a more visible range per gage section at an economical price. This glass gage series uses the proprietary Jerguson 25mm glass, which is thinner, narrower, and longer than traditional gage glass. The Series 300L features a recessed gasket surface, bar-stock non-shrouded covers, and ASTM grade bolting. Due to the length of each gage section this model is not recommended for high pressure steam service. All Jerguson armored flat glass gages are hydrostatically tested prior to shipment at 1 1/2 times the design pressure rating at 100°F (38°C).

    Jerguson Series 32 Liquid Level Gages, Reflex R-32 and Transparent T-32, Armored Flat Glass Gages

    The Jerguson Series 32 liquid level gage looks very similar to a Series 20, with the exception that the Series 32 armored glass gage features recessed mid-span supports or tie-bars to allow for increased pressure ratings. This is very important as other brands do not recess their mid-span support which causes a blind spot in the vision. A recessed gasket surface provides positive location of the seal gasket during both assembly and field repair and also makes it possible to repair a Jerguson gage while it is mounted to the vessel. The recessed gasket surface is also an important safety feature in the fact that it contains the gasket and helps prevent lateral movement which could lead to a gasket blow-out (as with competitive gages.)

    Jerguson Series 40 Heavy Duty Liquid Level Gages, Reflex R-40 and Transparent T-40, Armored Flat Glass Gages

    The Jerguson Series 40 liquid level gage is used in heavy duty, high pressure process applications of 4,000 psi, or saturated steam applications requiring a 1,500 WSP rating. Jerguson Series 40 armored flat glass gages are simple, rugged instruments engineered to provide accurate liquid level readings for the life of the vessel they are installed. All liquid level flat glass gages are hydrostatically tested by Jerguson prior to shipment at 1 1/2 times the design pressure rating at 100°F (38°C).

    Jerguson Series 51 High Pressure Liquid Level Gages, Transparent T-51, Armored Flat Glass Gages

    The Jerguson Series 51 liquid level gage is a specially designed instrument capable of withstanding high pressures. The one-piece chamber of the Series 51 armored flat glass gage is machined out of solid bar stock carbon steel or stainless steel as specified. It is drilled lengthwise and crosswise at each port leaving tie-bars in between to resist deflection under pressure. The Viton O-rings that seal each port are unaffected by most liquids that cause deterioration in rubber. The O-rings are seated in recessed circular channels to assure proper seating action.

    Jerguson Series L10 Large Chamber Liquid Level Gages for Boiling / Flashing Liquids, Reflex and Transparent Armored Flat Glass Gages

    The Jerguson Series L10 large chamber liquid level gages are designed to give an accurate liquid level reading of liquids that have a tendency to surge or boil. These armored glass gages are highly effective in reducing the boiling effects of entrained gas being released under low pressure. They are effective at eliminating level fluctuations that occur in standard gages with small chambers when boiling / flashing vapors try to rise to the surface. Jerguson Series L 10 large chamber armored glass gages are available in reflex or transparent design. The liquid chamber is constructed of heavy tubing, carefully slotted, and machined to provide plane seats for the gaskets and glass assemblies. Covers are steel secured with specially designed steel bolts.

    Jerguson V-Series Bronze Tubular Glass & Valve Sets, Tubular Glass Level Gages, Liquid Level Valves for Tubular Glass Gages

    The Jerguson V-Series bronze gage valves feature VA & VC Automatic and VB & VE Non-Automatic glass gage valves. The VA Automatic series comes complete with corrosive-resistant ballchecks for automatic closure in the event of glass breakage. The VB Non-Automatic series is similar to the VA series except ballchecks are not standard, thus making operation non-automatic. The VC Automatic series conforms to ASME power-boiler code requirements and feature stainless steel ballchecks in both upper and lower units, thus providing automatic closure in the event of glass breakage. The VE Non-Automatic series is nearly identical in every aspect to the above models, except for the non-automatic design and ballchecks are not included.
