Panduan memilih tipe flow meter

After exploring how each flow meter works the way it does, learn more about which is the best fit for your needs and why. The price of the meter technology is one aspect to consider as well as installation and life cycle costs for the total ownership cost (includes factors such as footprint, flow conditioning, maintenance and calibration requirements).

1. Coriolis – $$$, total cost $$

Accuracy 0.05%


  • Best measurement accuracy

  • Measures mass flow, liquid density and temperature

  • Flow profile insensitive

  • Unaffected by changes in temperature and pressure

  • Best rate of turndown

  • Suitable for gas, liquids, or slurry measurement

  • Able to measure high viscous fluids

  • Bi-directional

  • Low maintenance

  • Highly repeatable

  • Reliable


  • Pressure drop might be higher (appropriate sizing mitigates)

  • Susceptible to severe system noise

  • Limited in large line sizes (>12″)

  • Low flow rates may result in lower measurement accuracy

Typical Applications

Custody transfer by mass and/or volume, precision batching, filling/dispensing, loading/unloading, continuous process control/monitoring, mass balance, density and/or concentration measurement, blending, utility metering, chemical injection, allocation, fuel consumption

2. Magnetic – $$, total cost $

Accuracy 0.15%


  • Not constrained by Reynolds number or flow profiles

  • Immune to process variable changes such as temperature

  • High range of turndown

  • Negligible pressure loss with no obstructions

  • Able to handle large particles and chemicals

  • Not sensitive to variation in fluid velocity

  • Large line sizes

  • Variety of wetted path materials

  • Low power

  • Bi-directional
