Magnetrol Eclipse 706 Guided Wave Radar Level Transmitter

Name: Magnetrol Eclipse 706 Level Transmitter – Datasheet & Quote
Brand: Magnetrol

Description

Overview

The Magnetrol Eclipse 706 (Eclipse Model 706) is a loop-powered, 24VDC guided wave radar level transmitter engineered for high-performance liquid and solids level measurement across a wide range of industrial process conditions. Using diode switching technology, a single Eclipse 706 transmitter can be interchanged across multiple probe types and configurations, giving plant engineers flexibility to standardize on one transmitter platform for tank gauging, interface detection, and vessel level control rather than stocking model-specific electronics for every probe style.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the Eclipse 706 guided wave radar transmitter to refineries, petrochemical plants, and industrial facilities across the Sultanate of Oman and the wider GCC. Every unit supplied through Seven Star LLC comes with manufacturer calibration documentation and access to regional technical support, giving buyers in Muscat and beyond support with selection before ordering.

Operating Principle

The Magnetrol Eclipse 706 measures level using time domain reflectometry: a low-energy electromagnetic pulse travels down a waveguide probe inserted into the vessel, and when the pulse encounters a change in dielectric constant, such as the surface of a liquid or solid, a portion of the energy reflects back to the transmitter. By precisely measuring the transit time between the emitted and reflected pulse, the Eclipse 706 calculates the exact distance to the surface and converts it into a continuous level or interface reading.

Because the guided wave radar signal travels along a physical probe rather than through open air, the Eclipse 706 measures reliably even in the presence of foam, vapor, or turbulence that would degrade a non-contact radar or ultrasonic signal, and it is largely unaffected by changes in vapor space pressure, temperature, or specific gravity. This translates into practical benefits for the process engineer: consistent tank-gauging accuracy across varying process conditions, dependable interface detection between two liquids of different dielectric constant, and level measurement that continues to perform in visible vapors where other technologies would drift or fail.

Engineering Design of the Magnetrol Eclipse 706

The Magnetrol Eclipse 706 is built with an innovative angled, dual-compartment housing that separates the wiring terminal chamber from the electronics and LCD display compartment, improving field access for wiring and configuration while keeping the digital display clearly visible during commissioning and routine inspection. A comprehensive range of probe options, from single rigid and flexible probes to coaxial designs, allows the Eclipse 706 to be matched to the specific process fluid, vessel geometry, and dielectric characteristics of the application, spanning light hydrocarbons through water-based media.

Quick connect/disconnect probe coupling simplifies maintenance by allowing the electronics housing to be serviced or replaced without draining or de-isolating the vessel, and an onboard keypad with local display supports commissioning, diagnostics, and echo curve viewing directly at the transmitter. For deeper diagnostic work, the Eclipse 706 supports FDT/DTM device integration and enhanced HART communication, allowing technicians to view the full echo curve remotely through PACTware software for advanced troubleshooting and application optimization.

Operates reliably in visible vapors and ignores foam buildup that would interfere with non-contact radar or ultrasonic level technologies.
Carries IS, XP, and Non-Incendive approvals alongside ATEX, CSA, FM, IEC, and Inmetro hazardous-area certifications.
Communicates via HART, Foundation Fieldbus, PROFIBUS PA, or Modbus, supporting integration into modern and legacy DCS platforms.

Industrial Applications

The Magnetrol Eclipse 706 is widely deployed for tank gauging, interface detection, and vessel level control across crude oil storage terminals, refinery process units, and petrochemical plants where reliable measurement under foam, vapor, and turbulence is essential. In the Sultanate of Oman and across the GCC, refineries and petrochemical operators rely on guided wave radar transmitters like the Eclipse 706 to maintain accurate inventory accounting and safe vessel operation even under the varying pressure and temperature conditions typical of crude and refined product storage.

With fast quotation turnaround and technical support, Seven Star LLC distributes the Eclipse 706 to power generation boiler drum level applications, water and wastewater treatment plants, and industrial facilities operating within the Sohar and Salalah economic free zones, where accurate interface and level detection supports both process safety and regulatory compliance. Chemical processing plants and desalination facilities across the region also depend on the Eclipse 706’s SIL-rated reliability and hazardous-area certifications for continuous, unattended level monitoring.

About brand

Magnetrol is the American level and flow measurement specialist known for the Eclipse guided wave radar, Pulsar radar transmitters and the float and displacer switches that guard boilers and vessels. It was founded in 1932, is based in Aurora, Illinois, and has been part of AMETEK since 2021.

Seven Star LLC is an independent supplier in Muscat. We list Magnetrol level transmitters and level and flow switches, and supply them to refineries, gas plants and utilities in Oman and the GCC by complete model number.

Magnetrol products we list

Model	Principle	Typical use
Eclipse 706	Guided wave radar	Level and interface in separators, chambers and boiler drums, unaffected by changing density
Pulsar R80	80 GHz FMCW radar	Narrow-beam non-contact level in tanks with internals and in solids
Pulsar R86	26 GHz radar	Non-contact level in process and storage vessels
Pulsar R96	6 GHz radar	Non-contact level where vapour, foam or condensation are present
E4 Modulevel	Displacer	Level and interface in high-pressure, high-temperature vessels, often replacing older torque tube units
Echotel 961/962	Ultrasonic gap switch	High and low level alarms and pump protection
Thermatel TD1/TD2	Thermal dispersion switch	Flow and no-flow detection and level switching for liquids and gases

Guided wave radar sends pulses down a probe and times the reflection from the surface, so dust, vapour and changes in density don't affect the reading. That is why it often replaces displacers on separators and chambers. Non-contact radar suits tanks where nothing should touch the product, and a higher frequency gives a narrower beam that avoids tank internals.

Where Magnetrol instruments are used

In Oman and the GCC, Magnetrol transmitters and switches measure level in production separators, slug catchers, storage tanks, boiler drums and feedwater heaters, and protect pumps in oil and gas, refining, petrochemical, power and water plants.
