Air/gas mass flow meters find a variety of applications in many of today’s large urban water treatment plants, both clean water and wastewater. From measuring disinfection gases to controlling air or gas flow in digesters and aeration systems, the proper application, installation and operation of mass flow meters improves process efficiency as well as end product quality while at the same time reducing plant operating costs
Process, instrument and plant engineers are challenged continuously by productivity and plant operating efficiency objectives as well as ensuring plant compliance with an ever expanding list of regulations.
No matter how sophisticated a fluid analyzer system may be, it will be ineffective if a sample flow fails to reach the analyzer sensor or if the sample is contaminated or stale.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.
In today’s complex and frequently rugged process plant environments, liquid pumps are often over-worked and under-protected from adverse operating conditions. Many pumps run nearly non-stop 24-hours a day over multiple shifts. Poor operating conditions can reduce pump performance, require extra maintenance, shorten their lives and increase costs.
Many of today’s large urban water treatment plants rely upon sophisticated chlorination processes in order to provide clean, sanitary water to millions of consumers in the US and around the globe. The efficiency and cost-effective operation of chlorination processes in water treatment facilities can be significantly improved with the installation of flow meters that accurately measure the flow of chlorine gas in the treatment process
A company with multiple natural gas liquid (NGL) fractionation process facilities located in the Southeastern U.S became concerned about a series of missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief valves. The company wanted a highly reliable flow instrument solution that would detect a real event and avoid the lost productivity of nuisance alarms.
When looking for a way to reduce plant operating costs, one of the potentially simplest and often least expensive solutions is to measure liquid and gas flow more accurately. Plant upgrade projects that focus on the continuous improvement of flow measurement and control can trim overall production costs by eliminating waste and reducing maintenance costs.
A commonly encountered challenge is to develop pages that can be used on many screens where those screens may vary greatly in size, aspect ratio and resolution.
Recently, I received a call from an experienced system integrator regarding VTScada’s stance on installing updates on a SCADA server. They had a customer questioning advice from another SCADA software provider who has positioned themselves with the following stance. For the sake of the server stability, the servers should never receive any Windows® feature or security updates, ever.
