27.03 What is important about fuel meters?

Accurate fuel metering depends on (a) removal of entrained air in suction pump systems, (b) minimizing turbulence at meter inlet and outlet connections using minimum lengths of straight pip, (c) measurement of fluid temperature and compensation (other than for mass flow meters).

Meters used for custody transfer are commonly regulated by State and local agencies for accuracy, including periodic independent testing of accuracy.

Meters are used in generator fuel systems for a number of purposes:

• Measurement of fuel delivered to various generators when multiple tenants draw fuel from a common tank
• Filtration systems that operate based on the volume filtered in a particular cycle
• Measurement of generator or boiler fuel consumption for air quality regulation recordkeeping
