Jerguson® Magnicator® with Guided Wave Radar (MGWR™) (Clark-Reliance)

The Jerguson® Magnicator® with Guided Wave Radar, also known as the MGWR™ Series, combines two trusted level technologies in one level indication solution. It integrates a magnetic level gage with guided wave radar from a single set of process taps. As a result, operators gain true redundant level measurement with strong local visibility and an independent electronic level output.

The MGWR level indicator helps improve measurement confidence in applications where process visibility matters. The Magnicator uses a wide 1.5-inch indicator for clear level viewing. In addition, its magnet arrangement helps prevent skipped or missed flags. The guided wave radar transmitter also reads liquid level independently, even if float failure occurs. It can measure the true fluid level when product density varies.

The MGWR Series offers both single chamber and dual chamber designs. The MGWRS single chamber design uses a slotted internal baffle plate to separate the float and GWR probe. Meanwhile, the MGWRD dual chamber design separates the magnetic level gage and GWR into individual chambers. This design can also add valves, so teams can isolate either device while maintaining operations.

Westech Industrial offers the Jerguson MGWR level indicator Canada-wide. Our team can help with product selection, service support, application review, and integrated solutions. We can also support projects with custom fabrication capabilities when applications require broader measurement, monitoring, or packaged process solutions.

Description

Magnicator with Guided Wave Radar  (MGWR Redundant™) Measurement

The Magnicator with Guided Wave Radar (MGWR™) combines two trusted level technologies in one compact solution. It pairs a Jerguson magnetic level gage with guided wave radar from a single set of process taps. As a result, operators gain local visual indication and an independent electronic level reading.

This dual-technology approach helps improve confidence in critical level applications. The Magnicator uses density-based measurement through a sealed float. The float rises and falls with the process level inside the chamber. Meanwhile, the guided wave radar uses low-power microwave pulses along the GWR probe. The transmitter then measures time of flight to determine the liquid level.

Because the technologies work independently, the GWR transmitter can continue to provide level output if a float issue occurs. In addition, it can read true fluid level when product density varies. This makes the Magnicator with Guided Wave Radar a strong option for applications where reliability, visibility, and redundancy matter.

Wide Indicator for Clear Level Visibility

The Jerguson Magnicator helps operators confirm level conditions quickly. Its wide 1.5-inch indicator improves readability during routine checks. In addition, the indicator flags use a magnetically coupled arrangement. This helps prevent skipped or missed flags and supports dependable visual indication.

The magnetic level gage also uses the strongest magnetic field of any magnetic level indicator. Therefore, it delivers a clear local level display in demanding industrial environments. The standard chamber uses robust Schedule 40 minimum construction. However, teams can also select Schedule 10 options for light-duty or low-pressure applications.

Guided Wave Radar Performance

The guided wave radar transmitter adds an independent measurement to the Magnicator. It provides accurate level output and supports applications with changing process conditions. Its measurement does not depend on density, conductivity, dielectric constant, or temperature. It also handles foam and turbulent surfaces without affecting the reading.

Models are available for interface applications. In some applications, one HART signal can provide both total and interface level. In addition, teams can select guided wave radar manufacturers based on customer preference. This flexibility helps plants standardize instrumentation while still using the Magnicator with Guided Wave Radar package.

MGWRS Single Chamber Design

The MGWRS design combines the float and GWR probe in one chamber. A slotted internal baffle plate separates the two components inside the chamber. Therefore, the design reduces space requirements and helps limit potential weight concerns.

The baffle plate also helps reduce the effects of flashing or plugging in heavy particulate media. In addition, custom arrangements support applications where standard layouts do not fit. This makes the MGWRS a practical choice when teams need redundant level technologies in a compact footprint.

MGWRD Dual Chamber Design

The MGWRD design uses separate chambers for the magnetic level gage and guided wave radar. This arrangement gives operators more maintenance flexibility. Teams can add valves to isolate either device independently while maintaining operations.

The dual chamber design also reduces potential build-up in heavy particulate media. In addition, FlashProof designs support flashing or dirty service. Process connections can also come off either device, which helps support different installation requirements.

Alternative to Traditional Glass Gages

The Magnicator with Guided Wave Radar (MGWR™) can offer an effective alternative to traditional glass gages. It helps reduce maintenance, remove leak paths, and increase level visibility. It also performs well in foaming applications because it remains less prone to level fluctuations.

With ASME B31.1 and B31.3 design, the MGWR™ Series supports demanding industrial service. It also gives operators a practical way to combine visual indication, radar measurement, and true redundancy in one level solution.

The Jerguson MGWR level indicator supports common applications where operators need reliable level visibility, redundant measurement, and flexible installation designs.
