Described herein are systems and devices for controlling and monitoring liquid applications of agricultural fields. In one embodiment, a flow device for controlling flow during an agricultural operation includes an offset ball valve having multiple openings that rotate in position to control flow of a liquid through the offset ball valve to an outlet passage. The flow device also includes a first passage that provides a first flow path from an inlet to at least one opening of the offset ball valve and second passage that provides a second flow path from the inlet to at least one opening of the offset ball valve.

A technique facilitates evaluation of a fluid, such as a fluid produced from a well. The technique utilizes a modular and mobile system for testing flows of fluid which may comprise mixtures of constituents, and for sampling fluids thereof. The multiphase sampling method includes flowing a multiphase fluid comprising an oil phase and a water phase through a first conduit, the oil phase and water phase at least partially separating in the first conduit, mixing together the oil phase and water phase to form a mixed bulk liquid phase by flowing the multiphase fluid through a flow mixer toward a second conduit downstream the flow mixer, sampling a portion of the mixed bulk liquid phase at location at or within the second conduit, wherein the sampled portion of the mixed bulk liquid phase has a water-to-liquid ratio (WLR) representative of the pre-mixed oil phase and water phase.

Multiphase flowmeters and related methods having asymmetrical flow therethrough are disclosed. An example method includes configuring an inlet manifold, a first flowline, and a second flowline to decrease a gas fraction in a first fluid flow through the first flowline and increase a gas fraction in a second fluid flow through the second flow line; flowing the first fluid flow through the first flowline and flowing the second fluid flow through the second flow line; and determining at least one of 1) a first water liquid ratio of the first fluid flow through the first flowline; 2) a first liquid flow rate of the first fluid flow through the first flow line; or 3) a first gas flow rate of the first fluid flow through the first flow line.

Multiphase flow meters and related methods are disclosed herein. An example apparatus includes an inlet manifold; an outlet manifold, first and second flow paths coupled between the inlet and outlet manifolds; and an analyzer to determine a flow rate of fluid flowing through the first and second flow paths based on a parameter of the fluid flowing through the first flow path.
