Ashley Valley Water & Sewer Improvement District (AVWSID) serves rural county residents who live outside the city of Vernal, Utah.
Ultrasonic Flow Measurement System Saves WWTP $72,500 Annually
If the wastewater treatment plant serving Reading, PA, and 11 surrounding municipalities has a mission statement for its day-to-day operations, it couldn’t be simpler or more critical: “95°F.”
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.
New Developments In Thermal Dispersion Mass Flow Meters
This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature.

Advanced Diagnostics of Thermal Mass Flow Meters
Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.
Two Phase Flow Considerations For Coriolis Meters
Two phase flow is notoriously problematic for most flow technologies. Read how ABB is tackling the 2-phase flow problem through an entire meter-design approach, which entails a state of the art electronics platform and innovative sensor technology. By Ron DiGiacomo
Thanks To Digital Upgrade, Castle Rock’s Asset Management Becomes Model For State
With a population of 55,000, the town of Castle Rock, Colorado, was named to “Money” magazine’s list of 100 Best Places to Live in America. 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.
AMERICAN Valve And Pipe Groups Join Forces To Serve The Citizens Of Eastern Pennsylvania
Together, AMERICAN Flow Control and AMERICAN Ductile Iron Pipe are providing a complete package of valves, hydrants and pipe for a new waterline to serve the eastern Pennsylvania communities of North Wales and Chalfont Borough.
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.

Remote Monitoring Saves Money, Time For Rural Municipality
With outdated flow-monitoring systems, the Newtown Bucks County Joint Municipal Authority (NBCJMA) faced time-consuming communication gaps between the various sites of its large, decentralized sewer system. After bringing in engineering consulting firm Gannett Fleming, they installed remote telemetry units (RTUs) with solar power, eliminating the need for AC power or field visits to change batteries. Today, technicians can review data in a few minutes instead of a few hours thanks to frequent, regular delivery of data.
In London, Ontario, an aging combined sewer system created flooding issues, and the city’s outdated monitoring system provided unreliable and inconsistent data to indicate why. By installing a remote monitoring system, engineers were able to determine the exact source of the overflow problems. In this case study, find out how the implementation of wireless flow meters can lower operations and maintenance costs.

FLOW CONTROL AND MEASUREMENT
Flow measurement can be defined as quantification of the movement of water in a given channel. Flow can be measured either by determining the displacement and/or Velocity of the water. Water meters usually control measure and display total usage in cubic meters, on either mechanical or electronic registers.
Flow can be divided into two main flows which are: Open channel flow and Closed conduit flow. Flow is controlled by use of valves at intervals to either to slow down, allow faster flow or completely shut down the flow. Some water meters usually perform both the function or making readings and controlling flow while others just conduct measuring only.
Meters for reclaimed water contain special lavender register covers show that the water is non-potable. Velocity-type meters measure the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. Since Multi-jet meters are usually very accurate in small sizes they are normally used for residential and smaller commercial uses. Turbine meters are not as accurate as jet meters and displacement meters at low flow rates.
A compound meter is used where high flow rates are necessary. Magnetic flow meters are a velocity-type water meter, except that they use electromagnetic properties to determine the water flow velocity. In water treatment plants, measurement and control devices can be installed in the following locations: within interceptors or manholes, the head of the plant, in the force mains that lead to main tanks etc. Automatic Meter Reading has compelled producers to build pulse or encoder registers to provide electronic output for radio transmitters, reading storage devices, and data logging devices.
