WASTEWATER FLOW CONTROL AND MEASUREMENT WHITE PAPERS AND CASE STUDIES
A West Coast wastewater management facility provides design, management, and maintenance of the sanitary sewer system for an entire county, including the conveyance system and treatment system. The wastewater treatment plant has been established for over 50 years and has the capacity to treat 41 million gallons of sanitary sewage per day (mgd).value chain. Siemens suggested that the customer try the Siemens HydroRanger 200 controller. The HydroRanger 200 uses proven, continuous, ultrasonic echo ranging technology to monitor water and wastewater of any consistency up to 15 m (50 ft) in depth.
Wastewater Plant Relies On Thermal Flow Meter For Co-Gen Power Gas Blending Process
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.
Digester Biogas Flow Monitoring
A wastewater treatment plant needed to measure biogas traveling into and out of a gas line leading into a Digester Dystor gas bag. The amount of gas and direction of flow is critical for measurements to meet EPA regulations.
3 Dirty Little Secrets About Coriolis Flowmeters
Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.
From The 1970s To Today – 4 Key Advances In Coriolis Flow Measurement
Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.
Ultrasonic vs. Radar In The Water Industry
In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.
A Guide To Eliminating Pipe Breaks
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
Precise Biogas Flow Measurement
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.

Flow Meter Ensures A Smooth Running Recovery Process At Bakery Production Plant
Employing roughly 5,000 workers in 12 countries, Vandemoortele bakery and production plant owes its success to high standards of quality, innovative production technologies, and a flair for finding economic alternatives. The latest example is the SITRANS FC430 Coriolis flow meter.
Local Support Saves Time And Money
At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
A large east coast water supplier faced a number of challenges with one of its pumping stations. It was built more than 35 years ago on a 25’ earth mound (“ant hill”) to protect it from flooding, the pumping station was becoming very expensive and inefficient to operate.
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.
