Water Surge Prevention: Analysis Of Solutions And Alternatives
Water Surge could cause damage in a water conveyance system, from leaking pipes to serious breakdowns and accidents the consequences of which could lead to heavy financial costs and even loss of life. There are various solutions that are able to prevent or reduce the damage. It is important to know the differences between the solutions, and the advantages and disadvantages of each technology, before recommending the most suitable solution for the system.

Why A Little Knowledge About Sensors Can Be A Dangerous Thing
Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

Solving A Taste and Odor Problem Step By Step (Article)
The City of Alliance Ohio’s water system has experienced annual Taste and Odor (T&O) events since the mid 1950’s, when the first of two reservoirs, Deer Creek Reservoir, was placed into service. Nutrient contaminants, in particular phosphorous, in the watershed accumulate in the reservoirs causing algal blooms.

Versatility Of Thermal Mass Flow Meters
There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.
The Benefits Of A Venturi Meter
With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

Protecting Our Water – Keep Chemicals In The Tank
Leaking or overfilled tanks can cause environmental problems, contaminate drinking water, and cost a company millions of dollars. Proper instrumentation, monitoring and control can prevent these problems. By Bill Sholette, Level Products Business Manager, and Ricardo Chavez, Solutions Business Manager, Endress+Hauser
Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.

- Flow-through systems -Most research ships have built-in flow-through systems that constantly circulate water collected a few meters from the surface.
- Towed vehicles- towed vehicle such a system is able to provide a continuous series of data points for remote sensing applications where transect lines can follow the flight paths of a remote sensor.
- Moored platforms - These stationary, or Eulerian, platforms offer data streams synoptically that match with satellite-based imagers.
- Automated underwater vehicles - Autonomous Underwater Vehicles (AUVs) afford their own propulsion there by allowing high-resolution sampling of the ocean’s interior in multiple directions.
