Coriolis mass flow meter: High accuracy for high flowrates
In dry bulk solids flow-control applications, both batch and continuous, many materials such as cement, gypsum, fly ash, corn starch, and others flow at very high rates. Several types of mass flow meters, each with its own advantages and disadvantages, are available to measure these high flowrates. A good choice for a high-flowrate application that demands high accuracy is the Coriolis mass flow meter. After reviewing some mass flow meter basics, this article explains how the Coriolis flow meter works and how it achieves high accuracy.
A mass flow meter measures the flowrate of materials by weight per unit time and is a common component in dry bulk solids applications. Common batch applications for the mass flow meter include truck and railcar loading, where high flowrates are needed to quickly fill the carrier. A common continuous application is measuring the flow of gypsum to a gypsum-board production line. Of the many available mass flow meters, not every type can provide highly accurate flowrate measurements for a material flowing at a very high rate — that is, faster than 10,000 lb/h and up to as much as 200,000 lb/h. If your operation handles a material at a high flowrate, one solution to improving your flowrate measurement's accuracy is to use a Coriolis mass flow meter. This flow meter's operating principle eliminates some variables that reduce the accuracy of other flow meters in high-capacity applications.
