METERS, METER VERIFICATION, AND PROVER TANK.
Critical Tasks: 01-5103.00-0003
In this lesson you will learn how to operate positive displacement, turbine, and inferential meters; uses protective
devices; and uses a prover can.
TERMINAL LEARNING OBJECTIVE:
Describe the operation of positive displacement, turbine, and inferential meters,
understand the use of protective devices, and verify a meter based on the volume recorded by a meter and a 5-
gallon prover can.
You are a petroleum officer responsible for accuracy of all meters on petroleum
equipment IAW FM 10-67-1.
Placed in a role of a petroleum manager and given situational data, the you will identify
the various types of meters, calculate a meter correction factor based on the volume recorded by a meter and a
prover tank, and calculate the quantity of fuel issued using the meter correction factor.
Accounting for fuel is one of the most important aspects of operations in the field. If you are using meters for
accountability, then you must understand how they work in order to properly protect the meter and ensure that
they are properly calibrated.
Types of Meters.
Meters are devices used to keep track of the amount of fuel that flows through sections of pipeline and into or out
of storage tanks, tank cars, and tank vehicles. The use of meters can cut down on losses during fuel receipts and
a. Positive displacement meters. As the name implies, a positive displacement meter measures the flow
by separating the flowing stream into volumetric segments and counting them.
