It’s also a town on the cutting edge of managing its water, wastewater and storm water system assets with the help of the Hydrant and Valve Inspector from AMERICAN Flow Control (AFC) and Trimble Navigation.
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
Making Accurate pH Measurements
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.
Thermal Dispersion Technology Helps Utility Meet Federal Environmental And Health Regulations
Many water quality plants are using flow controls to help achieve critical operational goals.
How Larger Flow Meters Speak Volumes
As the price of water continues to increase, errors in flow measurement are magnified for distribution networks that transport large volumes of water. These systems often incorporate meters over 48 inches in diameter, which can be a challenge to calibrate. Learn how choosing the proper calibration method can ensure the most accurate measurements. By Richard Lowrie, Water and Wastwater Industry Specialist, KROHNE, Inc.
Continuous Phosphate Monitoring Improves Reliability
When municipalities choose to manually feed phosphates into their potable water, this often creates an over-feed of chemicals. Learn how employing an automatic-dosing phosphate analyzer can reduce operating costs and improve reliability.
Cyanide Analysis Of Wastewater Samples From FCC And Hydrocracking Operations
Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.
In 1974 the Congress of the United States passed Public Law 93-523; the Safe Drinking Water Act (SDWA) to protect public health by regulating the nation’s drinking water supply and protecting sources of drinking water. The SDWA first went into effect on June 24, 1977 and has been amended multiple times.
