McMillan”s Models 104 and 107 Liquid Flo-Sensors measure flowrates of fluids as low as 13 mL/minute and are designed as an electronic alternative to ball-and-tube rotameters. Stainless steel construction provides compatibility with a variety of chemicals, including many solvents and organic compounds. Offers +/- 1.0 percent linearity (full scale) and +/- 0.2 percent repeatability (full scale). An analog zero to five VDC output and pulse output are provided standard; four to 20 mA outputs and an integrated display are optional.
