Linear Range Smart electronics corrects for lower flow down to a Reynolds num-
ber of 5,000. The Reynolds number is calculated using the fluid
density and viscosity entered into the memory. Rangeability de-
pends on the fluid, process conditions and pipe size. Consult factory
for your application. Velocity rangeability under ideal conditions is as
follows:
Liquids 30:1 1 foot per second velocity minimum
30 feet per second velocity maximum
Gases 30:1 10 feet per second velocity minimum
300 feet per second velocity maximum
