n: a log used to determine the contribution of each zone to the total production or injection. These sureys are used to indicate chages in the flow pattern versus changes in conditions at the suface, in time, in type of operation, or after stimulation treatments;particularly useful for measuring gas well flow.

n: a produciton log used to determine which of several zones contributes the most to the total production or, in the case of an injection well, which zone is receiving the most injected fluids.

n: a length of straight pipe containing straightening vanes or the equivalent and installed at the inlet of a flowmeter to eliminate swirl from the liquid from entering the meter and causing measurement errors.

n: a device that measures the amount of fluid moving through a pipe. See orifice meter;positive-displacement meter.

n: a measure of the smallest increment of change in the pulse output of a flowmeter as it relates to the actual volume being measured.

n: 1. a constriction placed in a closed conduit of flowing fluid. 2. a flowmeter that depends on pressure head change to operate.
