Which Flowmeter Is the Most Accurate?

Coriolis mass flow meters produce the most accurate for most liquids but are expensive. They have the advantage of not needing any knowledge about the fluid being carried. Thermal mass flow meters are a less accurate but still direct measurement method. They do require knowledge of the fluid's specific heat capacity.

What is considered the most accurate type of flowmeter?

Among the most accurate of technologies available, Coriolis flowmeters are suitable for a wide and growing range of gas and liquid applications. These devices provide multiparameter data on mass, density, and temperature.

Which of the three flow rate meter types is the most accurate?

The Coriolis flow meters are in general very accurate, better than +/-0,1% with an turndown rate more than 100:1. The Coriolis meter can also be used to measure the fluids density.
