Mass-flow meter: Measuring material flowrates the gravimetric way
Are you measuring high-capacity material flow into your process? Or do you need to measure flowrates in a location that's short on head room or space for auxiliary equipment? One accurate, reliable device that measures high-capacity flow of nonsticky materials and has a compact profile is a mass-flow meter that operates on the Coriolis principle. After discussing how the meter is applied, this article explains how it works and looks at the equations behind the meter's operation. Other sections cover accuracy test results, system configurations and benefits for different applications, as well as a few selection tips.
What makes a good flow meter? Accuracy and reliability, of course. But depending on your application, other factors can come into play, too. These include the meter's ability to handle a variety of material and flow conditions, as well as the meter's mechanical simplicity, space requirements, and capital and operating costs. A mass-flow meter that uses the Coriolis force measuring principle is a simple, low-cost unit that can serve as a flow meter, a batcher, or a continuous feeder. It can accurately measure high material flowrates, handle changes in material properties, and fit into tight spaces.
