The complexity of flow measurement

The complexity of flow measurement Flow measurement is a complex and diverse technology, not only because of the increasing demand for measurement accuracy, but also because of the complexity and variety of measurement objects. For example, the fluid types include gas, liquid, and miscible fluid. The fluid working conditions range from high temperature to extremely low temperature, and from high pressure to low pressure. There are both low-viscosity liquids and very high-viscosity liquids. There is a big difference, the small flow rate is only a few milliliters per hour, while the large flow rate can reach tens of thousands of cubic meters per second. The pulsating flow and multiphase flow increase the complexity of flow measurement. On the other hand, this kind of complexity and diversity has promoted the research on the application of flow measurement instruments.
