The Ultimate Guide to Custody Metering Solution
2
Custody metering refers to the measurement of
fluids that are bought, sold, or transported
between different parties. Accuracy in custody
metering is crucial as it directly impacts
financial transactions and regulatory
compliance. Why Positive Displacement meter in
Custody metering ?
3
PD meters are notable in custody metering for
their ability to directly measure volume. In
contrast to flow meters such as turbine meters or
electromagnetic flow meters that depend on
velocity readings (which may be influenced by
variables like fluid density or turbulence), PD
meters offer a precise tally of distinct volumes,
guaranteeing accuracy and dependability in
measurement. Positive displacement flow meters
are favored in custody Transfer metering
applications for several reasons
4
Accuracy PD meters are known for their high
accuracy, typically within 0.1 of actual flow
rate. This level of precision ensures that both
buyers and sellers can trust the measurements for
billing and auditing purposes. Viscosity
Insensitivity Unlike some other flow meter
types, PD meters are relatively insensitive to
changes in fluid viscosity. This makes them
suitable for measuring a wide range of fluids,
from light hydrocarbons to heavy crude oils.
5
Low Flow Capability PD meters excel at measuring
low flow rates accurately, which is often a
requirement in custody transfer scenarios where
even small errors can lead to significant
financial discrepancies. Long-Term Stability
With proper maintenance, PD meters can maintain
their accuracy over extended periods, reducing
the frequency of recalibrations and ensuring
consistent performance over the meters lifespan.
6
Importance of WM certifications WM approvals
for custody meters are crucial as they ensure
legal compliance, accuracy in measurement,
fairness in commercial transactions, stakeholder
confidence, quality assurance, regulatory
compliance, and global acceptance. Legal
Compliance and Regulatory Standards WM
approvals, guarantee custody meters meet
accuracy, reliability, and performance criteria
for commercial transactions. Compliance with
these standards through rigorous testing and
certification processes is crucial for accurate
billing and financial transactions.
7
Accuracy Custody transfers involve exchanging
valuable commodities like oil, gas, and
chemicals. Metering system accuracy is crucial
for fair financial transactions, preventing
disputes, and ensuring trust in commercial
dealings. Global Acceptance and
Interoperability WM approvals align with
international standards from organizations like
OIML and NIST, ensuring custody meters are
accepted globally. This alignment supports
consistency in measurement standards, facilitates
international trade, and reduces barriers to
market entry for custody meter manufacturers and
users.

Liquid control metering systems are majorly
supplied in various downstream segments such as
terminal automation systems, tank truck
loading/unloading, and the aviation industry. Key
Benefits of Liquid Control Flow Meters Accuracy
and Precise measurement Liquid Controls (LC)
flow meters are known for their specialized
Tri-Rotor design. There is no metal-to-metal
contact within the metering elementand no
contact means no wearno wear means no increase
in clearancesno increase in clearances means no
increase in slippageand no increase in slippage
means no deterioration in accuracy. This helps in
sustaining the accuracy over longest period of
time. Metering system ensures sustained accuracy
better than /- 0.05 and 0.02 repeatability.

Accurate Measurement at Low Flow Rates In
custody transfer applications, accurately
measuring low flow rates is critical. Liquid
Controls meters excel in measuring low flow rates
with high precision, ensuring that all quantities
transferred are accurately recorded, regardless
of the flow rate. Safety Security Pulsers are

12
Low Maintenance Requirements Due to their
specialized design and quality materials, Liquid
Controls flow meters have low maintenance
requirements. They are designed to withstand wear
and corrosion, reducing downtime and maintenance
costs associated with recalibration and
repairs. Compliance and Certification Liquid
Controls meters are typically certified and

requirements, including OIML, Nmi, WM (Weights
and Measures), ATEX PESO approvals. This
ensures that they meet legal metrology standards
for accuracy, reliability, and traceability,
making them suitable for custody transfer
operations where compliance is paramount.
13
Key markets  Liquid Controls robust design,
accuracy across varying conditions, and ability
to handle different fluid viscosities makes a
preferred choice for industries such as oil and
gas, petrochemicals, and other industrial
applications. Below are the applications where LC
PD flow meters are widely used in oil gas
segment
14
Refined Products Transfer  Positive displacement
flow meters are used in custody transfer of
refined products such as gasoline, diesel, jet
fuel, and lubricants. They are used in Highly
precise Custody Metering solutions in terminal
Automation TAS  Tank truck/Wagon loading
unloading applications, Fuel dispenser / Fuel
Bowser of refined hydrocarbons. LPG Metering  PD
flow meters are employed to measure LPG flows
accurately during custody transfer, ensuring that
the quantities sold or transferred are exact,
which is crucial given the high value of LPG.
15
Biofuels  With increasing focus on renewable
energy sources, biofuels like ethanol and
biodiesel are becoming more prevalent in the
downstream oil gas sector. PD flow meters are
