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%
Advantages
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
Disadvantages
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%
Advantages
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
Disadvantages
