A Greyline AVFM Area-Velocity Flow Meter monitors and data logs water discharged from the Bray Quarry to the South Raisin River. The Quarry is required to measure flow for environmental permit compliance.
After 16 years of service, the Long Sault WWTP replaced two older Greyline Open Channel Flow Monitors with new data logging OCF 5.0 models. This SBR treatment plant`s influent is measured with flow through two 6` Parshall Flumes.
In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for...
In a pit water purification system it was necessary to detect the discharge volumes. The operator wanted a regular and automatic transmission of readings. On the selected measurement place no mains power connection was available. Due to the risk of vandalism, it was not planned to install a switching cabinet.
See the NIVUS solution for this measurement task here.
Although there is enough water on earth, its uneven distribution, the rising population and our carelessness drinking water starts to get short. In the future more and more pipelines for drinking water will be built all over the globe. In order to operate huge and complex pipe networks efficiently, water flow measurement and flow monitoring will become necessary. The increasing efficiency of ultrasonic flow meters will make such calculations more and more effective.
Whether you are a researcher or an operator working with wastewater treatment processes, it is crucial to have access to highly accurate and precise data to get insight into the wastewater treatment processes.
Monitoring Sewage Flow is a critical tool for local governments, for water and waste-water utilities and for industrial plants. Sewage monitoring can prevent environmental disasters such as sewage overflow within populated neighborhoods or excessive waste flow into local lakes, rivers or sea. Sewage monitoring is also an important tool for short term and long term planning of the sewers infrastructure. Short term refers to just-in-time and cost effective maintenance. For example, sending the technical team to...
The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow.
Subsurface environments are critical not only as water resources but also for energy use including geothermal, CO2 sequestration and oil & gas operations. These sensitive environments are directly affected by anthropogenic activities, hence monitoring is essential. Temperature offers insight into a variety of physical properties and can be used for flow monitoring and flux quantification in the subsurface. Traditionally, point sensors have been used to collect temperature data; however, significant limitations...
The Township of South Glengarry installs a new Greyline AVFM 5.0 Area-Velocity Flow Meter to measure continuous discharge from their municipal sewage lagoon. The sealed ultrasonic sensor is mounted in a horizontal 12` PVC pipe. The AVFM replaced a magnetic flowmeter that was unable to measure seasonal low flow rates.
Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited by national and international regulations.
In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence...
With its high turndown and direct mass flow, our immersible thermal meters are the instrument of choice for measuring aeration basin air flow and monitoring digester gas. Our multivariable vortex meters are used to measure steam in the cogeneration processes, while our ultrasonic flowmetersare used for influent and effluent measurement.
Public water supplies face growing pressure to do more with less, from sampling and maintenance to data analysis and customer calls. In-Situ solutions help streamline data collection and provide real-time insights into your data to improve operational efficiency. Our water quality and water flow instruments reduce sampling time and maintenance, while our cloud-based data platform gives you decision-level data 24/7
The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a...
Greyline AVFM Area-Velocity Flow Meters are installed thoughout the country by Teletronic Denmark to monitor municipal sewage and stormwater. Application photos and descriptions illustrate flow monitoring in manholes and open channels.
