FAQ’s

What is a fuel consumption flow meter?

A fuel consumption flow meter is a precision instrument used to measure and monitor the exact amount of fuel consumed by an engine, generator, vehicle, or industrial system. It works by tracking the flow of fuel through the supply, and in return-line systems, calculating net consumption. These meters provide accurate, real-time data for efficiency analysis, cost control, and integration with fuel, MES, or SCADA management systems.

Fluidyne meter can measure all type of liquid fuels such as –

  1. High speed diesel
  2. Gasoline
  3. Blended fuels
  4. Furnace Oil
  5. LSHS fuels
  6. Ethanol and solvent fuels
  7. Hydrogenated vegetable oils

The meter is available as standard in 316L Stainless Steel material which enables use over a wide range of fuels.

Fluidyne flowmeters are designed to measure fuel accurately in both supply and return lines. For simple engines, a single-line meter on the supply side ensures reliable monitoring. In modern diesel systems with return flow, Fluidyne offers dual-line or compact differential flowmeters that calculate true consumption with high accuracy. Equipped with patented oscillating piston technology, these meters provide dependable data for fuel management, efficiency analysis, and integration with digital systems.

Yes, Fluidyne fuel consumption flow meters can be seamlessly integrated with fleet and fuel management systems.
