Those facing challenges in measuring fluid levels in hygienic applications should be aware of Bürkert’s new Type 8139 non-contact radar measuring device. Designed to provide highly accurate, continuous measurement for specialised tanks that contain difficult to measure fluids, the Type 8139 is optimised to meet the needs of the pharmaceutical, food and beverage and water industries.
Radar level measurement relies on a signal being emitted, reflected by the medium and then received by the device’s antenna. Differences between the emitted and received signal are then rationalised via sensors to provide a level reading.
For hygienic applications, this provides the advantage of non-contact level measurement, all important in minimising contamination. As a result, the Type 8139 is suitable for bioreactors, ultra-pure water storage tanks, clean agent storage, beer and raw milk tanks, as well as containers for liquid foodstuffs, water treatment tanks, mixing and equalisation ponds, intake channels and flocculant storage tanks.
What differentiates the Type 8139 from competitive solutions is how it applies its radar signals. Delivering a radar frequency at 80 GHz with a dynamic range of 120 dB ensures continuous radar measurement of the medium. Higher frequency translates to short radar wavelengths, improving the accuracy of received signals. As a result, the Type 8139 delivers a measuring accuracy of +/- 1 mm, regardless of temperature or pressure in the tank.
The medium itself can pose difficulties to traditional radar level measurement devices – but not the Type 8139. Media with poor reflective properties (a low dielectric level) can flummox devices with a low dynamic range. However, the 120 dB range of the Type 8139 radar signal is able to detect even the smallest of reflections, ensuring accurate measurement of substances with a low dielectric constant.
This is also of great value when measuring through foam, an issue inherent to beer tanks for example. A higher dynamic range means less radar signal attenuation is caused, ensuring results are still accurate.
Another challenge that the Type 8139 overcomes is the interference by equipment installed in the tank, such as heating coils and agitators. The 80 GHz frequency allows the device to focus emitted radar signals within a tighter cone, therefore delivering greater accuracy from received signals, as the tight beam avoids installed equipment that may otherwise interfere.
A narrower radar beam means more signal returns to the sensor. The high frequency also ensures that the Type 8139 can emit and receive signals through glass, steam and condensate. This is an advantage for hygienic end users utilising small, narrow or high tanks.
The Type 8139 is inherently compact, however its powerful signal enables a measuring range of up to 30 metres. The device offers an IP67 ingress rating as standard and a 4-20 mA output. Furthermore, it can withstand temperatures up to 150°C, which makes it ideal for steam in place (SIP) processes encountered in hygienic applications.
Options include a plastic horn antenna, threads with integrated antenna and flanges with encapsulated antennas to suit different mounting applications. The device is maintenance free, offers easy installation as well as the exceptional chemical resistance properties that are expected of all hygienic equipment.

BRAC is a Bangladesh based enterprise committed to working with communities to solve their problems by eradicating poverty and creating social enterprise while focusing on overall development including water and sanitation.
BRAC is working in eleven countries and reaches 120 million people, aiding the most marginalized people in extremely poor, conflict-prone, and post-disaster settings. Partnerships such as this is a necessary step in combatting the world’s water crisis as it enables our products and solutions to be put to work, where the need is dire, and they can make a great impact.
– If we want to make a real difference, we need partnerships. By teaming up with BRAC we can accelerate our efforts to deliver clean water to millions of people in need, and at the same time transform our business towards an even greater positive impact, says Mads Nipper, Group President and CEO.
Sharing the same values is what empowers this partnership to make great opportunities for taking the world’s water crisis head on and create ripples into communities in need around the world.
– BRAC is delighted to have signed a partnership agreement with Grundfos. We feel very much aligned with their work, values and products and are truly excited about the potential for the partnership to have huge impact through the delivery of safe water to millions of people living in poverty. I’m very much looking forward to seeing the partnership grow and flourish, says Lewis Temple, CEO, BRAC UK.
One of the key initiatives in our partnership is the WASH services. BRAC has been working on breaking the cycle of contamination due to bad hygiene and sanitation for nearly 85 million people in Bangladesh, who lack access to basic sanitation facilities. With our new and innovative technologies to remove contaminants from water, such as arsenic, salt, iron and other heavy contaminants we can help combat the water challenges while working together to advocate the case for universal access to clean water and SDG 6.
– With this partnership we set out to create opportunities, not only for the people who need access to safe water, we also get to demonstrate the benefits of our pioneering approach, gain valuable insights and mark ourselves as an innovative leader in delivering sustainable services, says Peter Trillingsgaard, Group Vice President, Group Communication & Public Affairs.

Water treatment project at INTEL worth millions
An Oregon state board has approved $120 million in publicly issued bonds to help finance a $600 million water treatment project at Intel.
In Oregon, a state board has approved $120 million in publicly issued bonds to help finance a $600 million water treatment project at Intel. According to Oregon Live, the state’s business development department plans to supplement that with $30 million from its own bonding authority.
According to state officials, Intel may request even more in the future. The company said they are trying to balance support for Oregon’s largest corporate employer against growing needs for bonding authority to help finance homebuilding to address the state’s housing crisis.
The tax-exempt bonds, known as industrial development bonds, cost the state little or nothing. It’s Intel, not the state, that is responsible for repaying them.
However, Oregon has limited private bonding authority. Officials with Business Oregon, the state’s economic development department, said they limited a request while they assess a potential request for bonds to finance housing construction.
According to Oregon Live, semiconductor production is a water-intensive process, as machines clean layers of material between each step in manufacturing. Intel uses nearly 3 billion gal of water each year at its manufacturing campus. According to Hillsboro officials, the project could reduce the company’s water use by a third.
Intel representatives told Oregon private bond committee members that in addition to conserving water, the project will enable additional manufacturing capacity in Oregon.
The company said it plans to expand its Oregon manufacturing site, beginning in 2019. According to OregonLive, Intel is talking with contractors and tradespeople about building a new, multibillion-dollar factory in Hillsboro.
“To continue innovating and manufacturing in Oregon, Intel is investing in adaptable waste management systems,” Intel said in a written statement Tuesday. “The support of Business Oregon and the Oregon Private Activity Bond Committee to finance this project will help further economic development, environmental sustainability, and support the state’s small businesses through Intel’s supply chain impacts.”
In addition to the $120 million for Intel, the Private Activity Bond Committee voted to allocate nearly $115 million for housing, including $37.5 million for a first-time homebuyer program.
According to Oregon Live, the committee also approved as much as $15 million for a renewable energy program at the Port of Morrow.
