Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.
One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.
Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.
Accurate flow measurement is critical for process control and regulatory compliance. Flow meters are essential instruments for water and wastewater facilities, installed at multiple locations throughout entire systems. For the most part, these are permanent installations. However, portable flow instruments prove beneficial in certain situations.
In its quest to gain greater remote accessibility and increase ease of use, a progressive sewerage authority elects to think outside the traditional SCADA box.
Flanders pioneers the internet of Water, a unique intelligent water management system based on a network of connected sensors, that enables a permanent and real time follow-up of water quality and water quantity. This internet of Water will enable Flanders to tackle the growing threat of water inconvenience, water scarcity and water pollution.
Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.
Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.
Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.
Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.
