(1) Specifications for volumetric flow rate are based on a process-fluid density of 1 g/cm

(1000 kg/m

). For fluids with density other than

1g/cm

(1000 kg/m

), the volumetric flow rate equals the mass flow rate divided by the fluid’s density.

Typical accuracy, turndown, and pressure drop with CMF100 and 2400S or enhanced core processor

The graph below is an example of the relationship between accuracy, turndown, and pressure drop when measuring the flow of

water with a Model CMF100 sensor and Model 2400S transmitter or enhanced core processor.

Actual pressure drop is dependent on process conditions. To determine accuracy, turndown, and pressure drop with your process

variables, use the Micro Motion product selector, available at www.micromotion.com
