As the WaterLOG product manager for YSI, I am constantly asking myself the question, “How can we get quality data to our customers in a more efficient, reliable, easier way?”

Sometimes I forget to ask myself, “How can we provide support and service to our customers in a more helpful way?” At YSI we are constantly fine-tuning our support mix to optimize how we offer support. Our goal is to 1st provide you with quality, reliable products that make your data collection as easy, accurate, and secure as possible and 2nd, to make sure we are providing the support you need. The support we offer should both help you get the right products to meet your needs before you make the purchase, and then to help you program, install, and maintain the equipment for the life of the product. We never want to leave you hanging.

In our Winter Q1 2015 Newsletter I introduced a direct WaterLOG support phone number: +1-937-767-2772. This helped to by-pass the regular Xylem phone tree to get you right to our WaterLOG support team. Our numbers show that the majority of all support calls for WaterLOG are coming through this number. So, I hope we can see this as a success.

To further enhance our support team we have recently made some adjustments. Let me introduce you to our front line support. These are the people that will be on the phone when you need help:

Once a year, Xylem gives a few of its employees the opportunity to join with our Nonprofit partners to work in the field on projects to deliver safe sustainable clean water and clean sanitation solutions. This year I was fortunate to be one of the 13 selected to participate.

My journey started Thursday the 13th of August 2015 with a flight from Salt Lake City to Seattle, to Hong Kong, to Kolkata, India. I arrived on Saturday the 15th of August. A little bit like time travel! I was met by Swagato Mitra from our Nonprofit partner Water For People, at 12:30 – Midnight!

Saturday August 15th was India Independence Day, because of the potential enthusiasm of the Indian locals; all foreigners were asked to stay in the hotel. Since we were being supported by a responsible corporation, I obliged their request. However, on Sunday, the entire team of Xylem employees and Water For People hosts were finally together, so we spent the day recovering from time travel (jet lag) and acted more like tourists in Kolkata than humanitarian aid workers.

Sustainable Solutions

In partnership with Water For People, Xylem has participated in the implementation of deep ground water wells that supply safe clean drinking water to hamlets around Kolkata. These are water sources shared by the community as well as installed on school grounds for the use of the school children. In addition to clean drinking water, toilet facilities have also been installed in homes and schools. This provides private, safe facilities where the only drinking water source has been a local contaminated river and where open defecation or open sewage canals are common.

Our job as representatives of Xylem was to monitor the success of these programs. We visited both hamlets and schools to see the state of the water source and toilet facilities that had already been installed. This information is recorded using a smart phone APP. The data is then integrated into a data base that allows Water For People to provide continued support to these sustainable solutions.

The experience of meeting these wonderful people in India was beyond words. As we entered each hamlet and school yard, we were treated like rock stars. Our work there has provided improvements that are truly life changing for these people.

top of India, and traveled by taxi to our Xylem office in Gurgaon to join up with our Xylem sales team on Monday August 24th. With Sham Chaudhari and Rajiv Bhatia, I traveled to several key cities in India to visit our dealers and customers. Our first stop was in Electronic City, Noida, where we met one of our very successful dealers, Essel Shyam. They support a large successful network of our H-522+ DCP’s with INSAT satellite transmitters.

From Delhi, we flew to Pune, found on the western side of India near Mumbai. In Pune we visited Mechatronics Systems. This very successful group supports a network of hundreds of systems that monitor and control irrigation channel gates. Using a very impressive software, they have access to all the control stations across the country from their PC. This dealer also supports a system of 250 WaterLOG 5000 series data acquisition systems. These systems are used for hydro-meteorological measurements.

From Pune, we flew to Hyderbad, this city is found a bit south of the center of India. It is in Hyderbad that I visited with the National Collateral Management Services Limited (NCML) group. This group has it’s own weather station network of over 3000 stations that they support and collect data used in the agricultural industry for crop insurance. They also support a couple other smaller networks (only 100 stations!) of WaterLOG H-500XL data loggers used for research.

We flew out of Hyderbad and landed in Chennai. This city is located on the most southern east side of India, right on the coast of the Bay of Bengal. We traveled to Chennai to meet with the National Centre For Sustainable Coastal Management (NCSCM). This group works with our dealer in Chennai, Elektronik Lab. An incredible project is underway to cap-off the top of a bay to create a fresh water lake. Twenty-seven WaterLOG 5000 Series monitoring stations with radar level sensors are being used to measure the tide in this dynamic bay.

So, I arrived in India on the 15th and left on the 29th. I don’t know if I could have imaged a country with more contrast than India; color and smells, to buildings and jungle – and billions of people! From North to South and East to West, WaterLOG systems are operating in all these conditions.

WATERLOG H-3553T BUBBLER OVERVIEW

White Paper D69 0915October 2015

Water level and stage monitoring has become increasingly significant with environmental climate change. With that in mind, water level monitoring equipment has evolved over the years to support end-user research.

Combining our previous expertise, with feedback from the water level monitoring community, WaterLOG engineers designed the H-3553T Bubbler. The Bubbler has been rigorously tested in the factory and in the field, to make sure it provides high quality data, and maintains a safe, user-friendly design.

The H-3553T Bubbler is used to measure fluid levels in surface water, ground water, and tanks through a regulated bubble rate. A sophisticated system of sensors and valves control the bubble rate, and a compressor and tank replace the dry nitrogen tank used in previous systems—ensuring a safer site.

Designed to be used with a Data Collection Platform (DCP), the Bubbler is best suited for installation in a gauge house, turnkey enclosure, or similar structure, (where it will not be jarred or shifted during operation). A microprocessor determines how much pressure is needed in the tank, based on the current head pressure, to produce a constant bubble rate.

The WaterLOG H-3553T Bubbler also has a pressure sensor that measures the pressure required to push a bubble out of the orifice line, (also known as the line pressure). The line pressure raw value is

WaterLOG H-3553T Bubbler Attributes:

WaterLOG has been in the bubbler industry for 20 years, and as such will continue to surpass and improve bubbler technology based on experience and following the needs of the water level monitoring users. Water users will come to the conclusion that the WaterLOG H3553T Bubbler was built for accurate data collection, lasting durability, and designed with the end user in mind.

returned in pressure (PSI) unit, and the continuous display provides a readout of the last measured value for quick reference.

The benefits of the continuous bubble are response and accuracy. When stage increases with a continuous bubbler it senses this change, and within 30 seconds adjusts the tank pressure to keep the line pressure continually following the current water level. Bubblers measure water level based on the pressure it takes to push out a bubble. If that bubble is delayed due to not being continuous, then the data read and recorded is delayed by the response time. Therefore, accuracy is affected greatly by a continuous, consistent pressure in the line driven by pressure to push a bubble out. The quicker the response, the more stability there will be in the reading—which is how WaterLOG keeps high accuracy.

A purge feature, temporarily pumps up the tank and opens a valve to apply high pressure to the orifice line when needed. This feature is designed to remove any sediment that may have collected in or around the outlet of the orifice line. In addition, a manual purge can be initiated at the touch of a button.

Pair the Bubbler with our Storm 3 Data Logger to view data online in near real-time through our Storm Central data hosting platform. The ability to pinpoint data from any time range on graphical and tabular displays, will also make the system a big tool for those relying on the site monitoring data for research.

Located on the coast, in the northern part of the municipality of Al Daayen, is the site for the newest symbol of Qatari progress —Lusail city. Lusail city will include man-made islands and a host arena for the 2022 FIFA World Cup.

As part of the construction, a local dredging project is taking place. The focus of this project is to transform the current shoreline by increasing depth of navigation channels and creating the man-made islands for Lusail.

Though dredging is a necessary routine in waterways, it is not without its challenges. “Dredging, if unmonitored, can cause high sediment concentration, which will have a negative impact on the ecosystem,” explains Xylem Regional Manager Hassan Al Salem. The extent to which dredging can impact the ecosystem varies depending on a number of factors, however, monitoring can help officials maintain a safe environment during construction.

Water Quality Is Key

Recognizing that water quality monitoring is key to ensuring protection of the ecosystem, the local environmental agency took action and installed a network of eight water monitoring buoys. Each buoy contains a YSI EXO2 Sonde, and Storm 3 Data Logger with real-time data via GPRS.

Set to to collect data at designated time intervals, the EXO2 Sondes and Storm 3 data loggers seamlessly work together to monitor turbidity and dissolved oxygen (DO) at the sites. Designed for quick and easy calibration, the sondes allow long-term deployment with minimal maintenance.

Delivering The Data

The ability to deliver data quickly was the main challenge for these sites. “Dredging equipment is expensive to operate, and even more expensive when not operating,” explains Al Salem.

The innovative technology of the Storm 3 data loggers, automatically push the data to Storm Central, a cloud based hosting system, allowing real-time monitoring of the sites without sending a technician into the field. Collection of data obtained remotely from the buoys, is a safer, and a more cost efficient method than traditional water quality measurements by routine boat patrols, and allows water quality to be monitored during storm or other events.

“Online monitoring of the water quality helps in providing efficient operation while insuring the ecosystem will not be effected, “ continues Al Salem.

To ensure water quality remains at safe levels, Storm Central is set up to initiate an alarm via SMS text or email if a threshold of 10 Nephelometric Turbidity Units (NTU) is exceeded. In addition to email and text alarms, officials can quickly check site icons, which change colors with changing conditions, and assess data in both graphical and tabular display.

With the help of Xylem brand instruments and advanced water monitoring technology, officials will be able to identify harmful water quality levels and take action, if needed, to protect the surrounding ecosystem while constructing Lusail city.
