When I first came to Trihedral, I was surprised to learn that voice modems were still widely used in the HMI and SCADA industries. Though the days of wedging your phone receiver into a foam cradle are long gone, the name still conjures up the sounds of chirps, bleeps, and bongs they make as they translate analog information into digital. As high-speed networks became our preferred method of web surfing, the use of this technology has steeply declined.
The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant’s management team became interested in pursuing the gas-to-energy power co-generation system for both environmental and cost reasons.
Contact ultrasonic level switch technology was first applied to process control in the 1960s – and continues to provide accurate and reliable liquid level measurement in virtually every process industry today.
United Water, a division of the global conglomerate Suez Environement, operates regulated water systems in eight states, and provides contract services to over five million people.
In level measurement and specifically non-contacting level measurement, ultrasonic and radar technologies are popular across many industries. They both rely on the time of flight principle to determine the distance to the target or material from which the level can be determined.
Serving an area from eastern San Marcos to northwest Seguin, Crystal Clear Water Supply Corporation (CCWSC) recently commissioned their integrator, Central Texas Water Maintenance (CTWM) to replace their Wonderware and WIN-911 systems with VTScada software from Trihedral.
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments
When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.
Flow measurement instrumentation options abound, and the challenge of picking the right one for a particular application can be daunting.
The Industrial Internet of Things (IIoT) industry is growing at a rapid pace. By year-end 2015, an estimated 13.4 billion IoT-connected devices had flooded the global market.
As Wastewater Manager for four sewage treatment plants spread across Colchester County, Nova Scotia, Nicole MacDonald faced the daunting task of ensuring all systems continued to function seamlessly on a 24/7 basis. Each plant had its own separate monitoring and control system that allowed it to function autonomously
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.
Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.
In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.
The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
The journey to “smart” has proven more challenging for wastewater networks than for potable water, but real-world impact is imminent. Learn what potential awaits the industry at monitoring’s latest frontier.
A smart-water expert details the impact of data and analytics on the water sector.
Big Data is often characterized by the large volume of data, the wide variety of data types and the velocity at which the data must be processed. Data can come from many different sources, such as social media use, online purchases, licensed twitter data streams or sensors used in the Internet of Things (IoT).
AWWA's Annual Conference & Exposition (ACE) hits The City of Brotherly Love with a flurry of new technologies.
Cities that champion infrastructure improvements and embrace connectivity are well on their way to attracting today’s citizens and encouraging growth. Here’s a look at the benefits a smart city provides for its residents, workforce, and visitors.
