    Milltronics SF 500 Note: The Milltronics SF 500 is to be used only in the manner outlined in this instruction manual. The Milltronics SF 500 is a full-feature integrator for use with solids flowmeters. The SF 500 processes the signal from the flowmeter and calculates values for the rate of material flow and totalization.
