Flow measurement with compensation

The Rosemount 3051SMV from Emerson Process Management provides mass and energy flow measurement through patented compensation techniques. It provides full compensation of over 25 different parameters and claims a five-fold improvement in flow performance compared to uncompensated differential pressure flow.

In operation, the user enters three application parameters and the Engineering Assistant software performs the rest. This includes Joule-Thomson correction and sensor matching with Callendar-Van Dusen constants. The 3051SMV updates flow measurement 22 times per second so users can more effectively track production, demand, and total usage for process gas, steam, and natural gas.

The Rosemount 3051SMV allows users to specify the level of compensation that best matches the application. It can be scaled to optimize flow measurement in four different applications: full compensation (differential pressure, line pressure, and temperature measurement) for gas, natural gas or steam; differential and line pressure measurement for saturated steam; differential pressure and temperature measurement for liquids or saturated steam; and differential pressure measurement for liquids at stable temperatures.
