MIL-HDBK-1022A
6.4.1
Interstate Requirements. Provide piping system in
accordance with 49 CFR Part 195, as well as any applicable
local or state regulations for environmental protection.
6.5
EQUIPMENT. Equip all pipelines with meters,
strainers, and capability of installing a proving meter.
6.5.1
Meters. Equip pipelines which include one or more
water crossings 200 feet (60 m) or more from bank to bank and
other critical areas with at least two meters, one on either
side of the crossing(s). Use meters with an accuracy plus or
minus 0.5 percent for custody transfer and as required by
applicable codes when used for leak detection. Technologies
other than the two listed below are acceptable when meeting
the accuracy requirements.
6.5.1.1
Positive Displacement. Require flange-connected,
cast steel bodied positive displacement meters of the desired
pressure and flow rating for the applicable service
requirements. Ensure that meter has temperature-compensation
(where there is a custody transfer), adjustable calibration,
register and pre-set capabilities. Ensure meter accessories
are compatible with either the mechanical or electronic
support equipment selected. Consult the appropriate Service
Headquarters for requirements for the meter to communicate to
a remote location or equipment.
6.5.1.2
Turbine. Use flange-connected, steel bodied turbine
meters of the desired pressure and flow rating for the
applicable service requirement. Ensure meter has temperature-
compensation and adjustable calibration. Ensure all
supporting equipment for meter is compatible with the turbine
meter selected. Consult the appropriate Service Headquarters
for requirements for the meter to communicate to a remote
location or equipment. Consider the use of a card-operated or
key-operated data acquisition system. Cards or keys, as
appropriate, are coded to identify the receiver of the fuel
and to allow access to the fuel. The quantities taken are
transmitted to a data-receiving device by electronic pulse
transmitters mounted on each meter, and each transaction is
automatically recorded.
6.5.2
Manual Valves. Consider the use of full port valves
on pipelines to allow pigging.
