47-602 F10 and F50 Flow Switches
15
To determine the actuating flow rates for liquids other than
water (approximate viscosity of 20 centistokes or less), a
specific gravity correction factor must be applied to the
water flow rates given in the table.
Example: The maximum adjustment for an increasing flow
rate with a liquid specific gravity of .70 in an 8"
line is: 230 GPM x 1.20 = 276 GPM.
