Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy
At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to sensor drift from the factory calibration. ...

How to get accurate flow measurements despite flow disturbers
Flow meter accuracy is critical for process control but can be hampered by upstream and downstream flow disturbers. This problem may be addressed during the design process, though in some circumstances it’s impossible to eliminate disturbers. What Are Flow Disturbers? Anything that impedes flow upstream or downstream of a flow meter is a flow disturber. This includes piping ...

Applications guide to mass flow measurement in the primary metals
Mass flow meters can provide precision measurement and control of proccss gases in many phases of plant operation. They make processes more repeatable and provide greater control over quality and costs. Sierra mass flow meters were designed for these purposes. They can make any plant more cost-effective in several ways: Aluminum Purification: Automated Gas Flow Control The last step before ...

Increase biogas production, aeration basin efficiency with the right flow meter
In our competitive economic climate, many plant operators have a mandate to tune their plant’s performance by efficiently using biogas in cogeneration processes and increasing aeration basin efficiency, both of which can save thousands of dollars in the critical secondary stages of wastewater treatment. In many cases, these facilities are retrofitting with new flow measurement ...

Where`s the fire? Industrial uses for fire hydrant meters
There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use ...

Flow metering with MaxxFlow HTC - Case Study
Application An important part of the production of cement is the processing of raw meal in the cyclone dust heater. During this process cement meal is heated by an airstream. Thereby CO2 is extracted from the cement. At the beginning of this process raw meal is stored in a silo, from where it is discharged via an air slide into a bucket elevator. The bucket elevator transports the cement up to ...

Know the flow
Flow meters don’t immediately come to mind when growers think of tools and technology they’re looking to implement on their farms. It’s not a new Kubota tractor, it’s not the newest app designed for agriculture, it’s not state-of-the-art harvesting equipment. In fact, some growers only hear about flow meters when they’re instructed by regulatory bodies to ...

How to avoid system downtime when installing flow meters
FPI Mag installed in pipe. 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 ...

In-Situ Calibration - Methods & Pitfalls of Thermal Mass Flow Meter Sensor Field Validation
Introduction Mid-to-large size facilities and campuses inevitably have hundreds of ¬ ow 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. These standards mandate that precision instrumentation needs to be checked (validated) or recalibrated as often as once a year. ...
