SYSTEM FOR SHUTTING-OFF FLUID FLOW AND MEASURING FLUID FLOW RATE

Abstract:

A system for shutting-off fluid flow and measuring fluid flow rate may include a housing defining an inlet, a valve body chamber, and an outlet opposite the inlet. The system may also include a valve body at least partially received in the valve body chamber, and an actuator coupled to the valve body and configured to reposition and/or re-orient the valve body. The system may also include at least one pressure sensor configured to generate a pressure differential signal indicative of a pressure difference between pressure at the inlet and the outlet, and a controller configured to receive a valve body signal indicative of a valve body position and/or orientation and the pressure differential signal, and determine a flow rate of fluid flowing through the housing based at least in part on the valve body signal and/or the pressure differential signal.
