An Economic Remote Power System Solution Providing Unparalleled Reliability


Qnergy (pronounced "q-ner–gy") provide reliable remote power with output in the 1 to 10kW range. Their core technology is a state-of-the-art, free-piston, Stirling engine which was recently recognized by NASA as the most reliable heat engine technology ‘in history’. Qnergy remote power generation platforms are designed for high-reliability, no-maintenance, long-life missions.

Qnergy Sterling Engine
Qnergy’s free-piston, Stirling engine.
Qnergy’s engine can use any heat source, the most common being natural gas, propane and biogas. Utilizing a  200 year old technology, Qnergy is the only company that has perfected a Stirling engine based, stand-alone power generator known as the PowerGen. It was introduced in the summer of 2017 to a variety of potential customers in a pilot ‘try and buy’ program. The results were so successful, all pilot customers ended up purchasing their systems. Since then, Qnergy has developed multiple specific use products around the PowerGen including cathodic protection, freeze-off prevention, well pad automation, solar power backup, and replacing methane bleeding with compressed air. This success has allowed Qnergy to become the preferred remote power source for many Fortune 500 gas companies.

Innovative Adapter Allows Easy, Less Costly Upgrade of Level Transmitter

Model 706 Adapter

Magnetrol International, a global leader in level and flow measurement instrumentation, has introduced an innovative product that allows for the retrofit and upgrade to a higher level transmitter package for existing guided wave radar (GWR) level probe applications.
The new Eclipse Model 706 GWR Adapter allows users to keep existing Eclipse 705 GWR probes in place, and upgrade to the Eclipse 706 transmitter and its advanced electronics and DTM.

The ECLIPSE 705 guided wave radar transmitter, with its patented easy-access, angled enclosure has gained wide popularity and has a huge installed base around the world.

The Eclipse 706 transmitter supports both the FDT/DTM and enhanced DD standards. A DTM (Device Type Manager), similar to device drivers used in computers, provides a user-friendly graphical interface to make device configuration, maintenance, diagnostics and troubleshooting a breeze. The DTM allows 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. 

Model 706 AdapterIn many cases, GWRs are installed in hard to access areas, where removing the sensing probe from
the tank or vessel is prohibitive. Additionally, or the integral electronics and cumbersome DTM of older Eclipse Model 705s is less comprehensive and less user-friendly than the newer Model 706s. 

The Model 706 Adapter allows existing Model 705 probes to be retrofitted with the Model 706 transmitter without breaking the process seal, gaining the best-in-class GWR performance that comes along with the Model 706 including the highest Signal-to-Noise (SNR) ratio in the market.  High SNR is particularly helpful in low dielectric liquids often found in refineries.

Aside from the increased performance, the technician could now use the latest Model 706 DTM for troubleshooting.  The main DTM features emphasized by users are:
  • The capability, on a single screen, to view not only the echo curve itself but also the operational conditions of the transmitter along with the configurable parameters.  You can then change parameters and refresh the curve to see immediate results without going into multiple screens.
  • Data logging capabilities where you can capture all of the data associated with the last nine events, which include configuration parameters, echo curve, echo curve history and event history.
  • The Model 706 has the capability to monitor build-up as a percent of level threshold or as a rate.  Meaning the user can potentially track the build-up percentage or rate through a HART variable to trigger a flushing process or for timely maintenance / cleaning intervals.
Benefits of the Eclipse® Model 706 GWR Adapter:
  • Backwards compatibility with existing Eclipses probes.
  • Extends the lifecycle of existing Model 705 probes.
  • The added benefit of facilitating the upgrade without opening up the process.
  • Lower cost because you are only replacing the transmitter and not the probe.
  • Compact design adds 3.15” of installation height.
  • Customers get all the features of the Model 706 Transmitter while using their existing Model 705 probes.
  • Adapters are in stock at Magnetrol
