E

r

where:

Q = volumetric flow rate
A = cross-sectional area
D = pipe section diameter
E

s

= induced signal voltage

E

r

= reference voltage

B = magnetic flux density

∝

= dimensionless constant

β

&

γ

= dimensional constant

V = fluid velocity

Therefore, volumetric flow rate is directly proportional to the induced signal voltage as measured
by the ABB Instrumentation Magnetic Flowmeter.
