L.A.C.T.
The word, L.A.C.T. stands for Lease Automatic Custody Transfer. That is the automatic transfer of fluid from a
lease to a pipeline without the need of outside measurement assistance. The design of, and the procedures for
L. A. C. T. units are provided in the Manual of Petroleum Measurement Standards (API).
A.C.T.
The word A.C.T. refers to the Automatic Custody Transfer of fluids other than at a lease unit. Such as a truck
meter, pipeline check meter. Pipeline delivery is from one pipeline to another. The design of and the
procedures for also provided in the Manual of Petroleum Measurement Standards (API)
Meters
Meters are a way of accurately measuring a fluid flowing thru a pipe, without stopping the flow. There are
several different types of meters. They include but are not limited to the following.
P.D. (Positive Displacement) meter is a meter that continuously divides the fluid into known volumetric
segments, counts each segment and reports this information to a totalizer.
Mass / Coriolis Meter is a metering device which by means of the interaction between a flowing fluid and the
oscillation of a tube, or tubes, measures mass flow rate and density
