The Magnetrol Eclipse 700 Guided Wave Radar Transmitter

Magnetrol Eclipse® Model 700 TransmitterThe Magnetrol Eclipse® Model 700 Transmitter is a loop-powered, 24 VDC level transmitter that is based upon the proven and accepted technology of Guided Wave Radar (GWR). Encompassing a number of significant engineering accomplishments, this leading edge level transmitter is designed to provide measurement performance well beyond that of many of the more traditional technologies.

This single transmitter can be used in a wide variety of applications ranging from very light hydrocarbons to water-based media.

One universal Model 700 transmitter can be used and interchanged with several different probe types and offers enhanced reliability as it is certified for use in critical SIL 2/3 hardware safety loops.

The ECLIPSE Model 700 supports both the FDT/DTM and Enhanced DD (EDDL) standards, which allow viewing of valuable configuration and diagnostic information such as the echo curve in tools such as PACTware™, AMS Device Manager, and various HART® Field Communicators.

A Little History

Pulsar® R86 Radar Level Transmitter
One of Magnetrol's recent innovations.
Some companies, through hard work, innovation, and good fortune, manage to stand the test of time and thrive for decades in a competitive environment. The manufacture of process measurement and control equipment and devices is an arena where standing still in the market is not a viable business strategy. Magnetrol has been helping process operators measure and control fluid level and flow for decades. The company recently posted an article on their own blog outlining a little of the company history as illustrated through product innovations. We include an excerpt from the blog below and encourage readers to share their fluid level and flow challenges with application specialists. Leveraging your own process knowledge and experience with their product application expertise to develop effective solutions.

This year marks the 85th anniversary of the founding of Magnetrol®. Since its very beginning, MAGNETROL has been a company focused on level and flow measurement innovation, designing cost-effective, cutting-edge solutions for its customers. In honor of 85 years of success, here’s a look back on some MAGNETROL highlights over the years. 
The Beginning
The history of MAGNETROL dates to 1932 as a Chicago-based manufacturer of boiler systems. The first MAGNETROL level control was born when the founding company, Schaub Systems Service, needed a controller for its boiler systems. Our innovative device was the first of its kind to accurately and safely detect the motion of liquid in boilers and feedwater systems. Soon the MAGNETROL name became synonymous with rock-solid, reliable mechanical buoyancy controls.

Mechanical buoyancy isn’t the only area where MAGNETROL has been a force for innovation. Our devices have changed the radar landscape as well. In 1998, we introduced the Eclipse® Model 705 as the first loop-powered guided wave radar (GWR) transmitter for industrial liquid level applications. The unprecedented reliability and accuracy of the ECLIPSE 705 set a new standard for radar devices.Innovation in Radar
We didn’t stop there, continuing to develop radar technology and adapt it to the needs of our customers. In 1999, MAGNETROL released the first ECLIPSE high-temperature/high-pressure probe, rated to 750 °F (400 °C). We developed an overfill-capable coaxial probe in 2000. And in 2001, we became the first company to incorporate GWR technology into a patented magnetic level indicator chamber, offering true redundant measurement.
In addition to these new developments in GWR, MAGNETROL created many pulse burst and non-contact radar devices for use in challenging process applications. We also secured our core capabilities in electronic technologies, including RF capacitance and ultrasonic.
 Looking Toward the Future
Most recently, MAGNETROL released the Pulsar® Model R86, a groundbreaking new 26GHz non-contact radar featuring a smaller wavelength for smaller antennas and improved 1mm resolution.
We continue to raise the bar for level and flow measurement. Whatever the future of industrial technology, MAGNETROL will be in the thick of it, developing the products that bring customers accuracy, reliability and peace of mind. We are a team of innovators—and innovators are always moving forward.

Guided Wave Radar to Lower Power Plant Costs

Reducing costs at power plants.
For most power plant operators, fuel expenditures account for seventy to eighty percent of production costs and millions of dollars per year. In fact improving heat rate one percent could generate five hundred thousand dollars an annual savings for five hundred megawatt power point.

To contain fuel costs, power plants must maximize the efficiency of their feed water heaters. That's why many companies today are focusing on improving heat rate as a way to use their feed water heaters more effectively, and significantly reduce their fuel costs.

Heat rate is a measure of how efficiently a power plant uses heat energy. You can measure heat rate by the number of BTU’s your plant requires to generate a kilowatt hour of energy. As you're heat rate goes up so do you're fuel costs.

The condenser is the beginning of the feed water heaters process, where condensed steam from the feed water heater drains, and HP, IP and LP turbines is routed through successive feed water heaters. At the same time,  extractions steam from your turbines reaches the appropriate feed water heaters and the transfer of energy takes place.

Maintaining accurate and reliable level control throughout this cycle is critical to achieving the final feed water heater temperature that your process requires.

Let's take a closer look at how this works.  Feed water heaters use the heat of condensation to preheat water to the correct temperature for the boiler. During this process, shell and tube heat exchangers allow feed water to pass through the tube side and extract steam from the turbine to the shell side.

The primary benefit of this process is that the feed water heater decreases the fuel costs by using recovered energy, rather than costly hot gas, to heat the water.

Achieving optimum water level in a feed water heater is a critical component of maximizing energy transfer and minimizing controllable losses.

There are normally six to seven stages of feed water heating. Making an investment in level control can help you achieve optimum heat transfer and improved terminal temperature difference to provide a significant return on investment.

With a guided wave radar level control, you can optimize the condensing zone of your feed water heater to deliver accurate level control, maximize energy transfer, and minimize undue wear and tear. This can help you generate the savings needed to recover your investment.

Older level technologies, such as differential pressure, magnetostrictive, or RF capacitance and torque tubes are vulnerable to process conditions and induced instrument errors, such as shifts in specific gravity and mechanical or electronic drift.

In contrast, guided wave radar provides a truly reliable level measurement solution for feed water heaters. Guided wave radar performance is virtually unaffected by process variations and gives you a superior degree of accurate and reliable continuous level measurement without the need for calibration or gravity corrections.

With superior signal performance and advanced diagnostics, guided wave radar delivers premier level control for feed water heaters, as well as a broad range of challenging applications, such as condenser hot wells, deaerators, and cooling tower basins.

Combining a magnetic level indicator with guided wave radar merges the operating systems of a conventional flowed base magnetic level indicator with a leading edge solution. This allows you to effectively measure low dielectric media, high temperature, and high pressure process conditions and media, with shifting specific gravity and dielectric values accurately and repeatedly. The result is a diverse and redundant level measurement solution in a single chamber design.
