Systems and methods for measuring phase flow rates of a multiphase production fluid are provided where a fluidic isolation chamber expands volumetrically in response to fluid pressure from a diverted multiphase production fluid. A pressure-regulating actuator regulates fluid pressure upstream of the fluidic isolation chamber and an upstream fluidic pressure sensor generates an upstream fluidic pressure signal. A fluidic control and analysis unit is configured to communicate with the upstream pressure sensor and the isolation chamber actuator to maintain fluidic pressure upstream of the fluidic isolation chamber as the multiphase production fluid is diverted to the fluidic isolation chamber. The unit generates a total flow rate Q.sub.TOT as a function of chamber filling time and volumetric expansion and communicates with the fluidic phase detector to generate a relative occupancy indicator I for a target phase of the multiphase production fluid in the fluidic isolation chamber. A flow rate Q.sub.P for the target phase is generated as a function of the total flow rate Q.sub.TOT and the relative occupancy indicator I.

There is described a method for controlling a liquid delivery system adapted to deliver a liquid in a container, comprising: receiving a desired temperature for a liquid to be delivered and a desired level of liquid within the container; adjusting a mixing valve connected to a source of hot liquid and a source of cold liquid to obtain the desired temperature; operating a flow control valve for delivering the liquid having the desired temperature and closing a drain closure system of the container and closing a drain closure device; monitoring a level of the liquid within the container; and closing the flow control valve when the monitored level of liquid substantially corresponds to the desired level of liquid.

A volume fraction meter that includes a flow meter coupled to a flow line. The flow line includes a turned portion and the flow meter is positioned upstream from the turned portion with respect to a flow direction. The flow meter is configured to measure a volumetric flow rate of a multiphase fluid flowing in the flow direction through the flow line.
