Density - The Other Vital Bit for Flow Measurement

Accurate flow measurement is vital throughout the process industry. In many process applications, density is used for process control and product quality assessment, whilst in the oil and gas sector it is required for allocation in shared transportations systems and for reporting annual production - the flow measurement system is, in effect, the cash register for the production facility.

Depending on the technology used, the flow rate may be measured by mass or by volume but there is often a requirement to convert between these quantities. This requires a knowledge of the density of the fluid, as a function of temperature and pressure. Density, therefore, becomes a fundamental part of the flow measurement system.

This webinar, presented by expert Dr Norman Glen, explores issues associated with on-line density measurement and calculation techniques for liquid density determination.
