Who are We?

With all the changes that have transpired in the past 18 months, this is a question we are asked frequently – “who are you?” I think what we are really being asked is, “what company now owns you?” or perhaps, “what company name do you go by?” But I would like to address the real question of, “who are we?”

To understand who we are is to understand what principles we value and how we see our role in the world around us—or in other words how we live.

our mission statement defines who we are

To fulfill our mission, We:

Respect: We recognize each person has equal value in the organization, and as such we value their contributions.

Seek knowledge: Because we live in a dynamic technology rich world, we seek after new ideas and information.

Are impactful: Everything we do makes a difference in the lives of others.

Are a community: We have a responsibility to our community. We will reach out to engage in activities and programs that unite and benefit us all.

These rules take priority in achieving our mission:

Team members – the most important individuals I work with are the members of my team. United we stand, divided we fall.

Customers – they are the reason we exist. Each day I will ask, “How can I make our Customers job easier?”

WaterLOG – my work here is a reflection of who I am. Each day I will ask, “Is that the best I could do?”

Xylem – hired me to do a job. I will speak with respect. I will provide solutions not problems.

The WaterLOG series of non-contact Radar water level sensors was introduced in 2002 with the H-360 Radar. This was followed by the H-3611-i Radar in 2005, and finally the H-3613-i in 2010. Throughout the years, several improvements have made the radar series into the high performance sensor that is a favorite among many users today. Read on and discover a few features of the radar series that will move this product to the top of your favorite list.

installation, Maintenance and Measurement

Installation in any environment has its challenges, but the quick and easy site installation of the radar series has become a known characteristic among customers. Because the radar sensor is typically installed on a bridge over water, there are several options for mounting—such as the quick mounting bracket that is provided with each radar sensor.

Site maintenance is also relatively low. Because this non-contact sensor has the ability to accurately measure up to 70 Meters (250 Feet), it eliminates most all water related maintenance issues, like floating debris hitting the equipment or orifice lines getting plugged. Its measurement range also gives the radar sensor the ability to standalone in difficult applications, while providing an accurate data collection solution.

Like other WaterLOG products, the radar sensor was designed to handle extreme monitoring environments. For extra protection from unwanted visitors, a complete mounting enclosure is also offered.

continuous Measuring, low power consumption

The radar sensor measures data continuously. When a measurement command is initiated, the radar simply collects the last 10 seconds of the previous measured data points, averages them, and returns the result. Because low power consumption is vital for remote battery powered site applications, the radar sensor never exceeds more than 0.008 Amps (or 8 milliamps).

MappingBecause each site is different, the possibility of always having a clear path to the water may not be possible. The radar sensor keypad and display offer the ability to quickly check the distance to water value, as well as provide site specific setups such as the “Mapping”

feature. The “Mapping” feature gives the user the benefit to provide a “Map” of what is between the radar sensor and the water as the signal travels to the desired water surface. After completing this “Mapping” feature, the radar sensor will cancel out any obstruction, returning data collected only from the water surface and nothing else.

As new technology develops, the WaterLOG Radar Series continues to be a reliable product for our customers. Highlights of this non-contact sensor are unique in the industry and will continue to be enhanced throughout the years.

The King Of Non-contact Water Level Sensors

Application NoteJuly 2014

For Centuries, a vast network of coastal lights—like the ones that still tower over Garden and Loggerhead Keys—safely guided mariners away from shoals, reefs, and other potential hazards. In the present, we routinely rely upon weather radars, depth finders, satellite radios, and GPS to guard against perial as we navigate the vastness of the ocean. In the years ahead, however, rising sea levels will pose a significant challenge for low-lying coastal areas like the Dry Tortugas. In response, an effort is currently underway to build a new network of instrumentation that may help deliver us from new dangers ahead.

a climate in Flux; a troubled coast

Our changing climate could drastically transform coastal areas in the coming century. Higher concentrations of atmospheric carbon dioxide may alter ocean chemistry to the detriment of some shellfish and plankton. Higher air temperatures and changing patterns of precipitation may change the composition and seasonal cycles of wildlife along the shore, including sea turtles, fish, and migratory birds. And a warming ocean could greatly hinder the survival of imperiled coastal species, including several types of coral found in the shallow waters of the Dry Tortugas.

But for coastal areas of only slight elevation, the most serious consequence of climate change will likely be sea level rise. A tide gauge operating on Key West since 1913 provides one of the longest instrument records in our hemisphere. Since that time, it has recorded an average of 2.36 mm of rise per year—a total of more than 9 inches over the past century. More importantly, scientific models suggest we are likely to experience an accelerated rate of sea level rise in the years ahead. Much like a spyglass might have helped mariners survey the waters ahead, tide gauges help bring long-term changes to our oceans into greater focus.

variability & local conditions

Though global average sea level is clearly rising, the magnitude of rise is not equal across all areas. Observed changes to relative sea level can be highly variable due to the influence of prevailing ocean currents, the rise and fall of land masses, or the compaction of coastal sediments. Differences in the rate and magnitude of rise

can be observed not only across continents, but also at much finer regional scales.

Although the data available from the Key West tide gauge is a good proxy for sea level rise in south Florida, the islands of the Dry Tortugas are located well over 70 miles away. Effective management of the park’s unique resources will require a more nuanced understanding of site-specific trends over time, and the park has recently installed a new instrument to meet this ongoing need.

gauging the tides

A new tide gauge was recently installed on Garden Key, which will record reliable sea level data at Dry Tortugas for the first time.

The sensor selected for this task works on microwave technology, measuring the distance to the water by recording the time it takes a signal to go from the sensor to the water surface and return. This type of instrument is well suited for the Garden Key site since it is capable of accurately

determining sea level even in the presence of waves, seagrass or large numbers of fish just below the surface. This type of sensor is considered very stable and has been used extensively at other tidally influenced water level stations around the globe.

Since the recording method is based on time, the sensor is also extremely stable, capable of delivering accurate values with very little maintenance for months to years. Information from the sensor is delivered via satellite to a NPS database where the data are reviewed for accuracy and further shared via the internet.

The addition of the new tide gauge at Dry Tortugas is part of a larger, national effort. Similar instruments are being installed at national park sites across the country to provide locally relevant data for long-term park planning.

What’s at Stake

Dry Tortugas National Park contains numerous resources of impressive beauty and significance. Because these treasures exist almost at the waterline, rising seas are likely to have a significant impact on their conservation over time.

Thus far, the wildlife of the area has managed to adapt to changing conditions, and the bricks and mortar of Fort Jefferson have somewhat withstood the assaults of wind and wave. But properly stewarding the park into the future will require diligently watching the surrounding waters over time. In the years ahead, the humble tide gauge may guide us more brilliantly than the flashing beacon of Loggerhead Light.

The faster a microwave bounces back and “returns” to the sensor, the higher the water level.
