Flow rate measurement device alternative to ball-and-tube rotameters
McMillan Co. offers the models 104 and 107 Liquid Flo-Sensor® that measures flow rates of fluids at 13 mL per minute and can be used as an electronic alternative to ball-and-tube rotameters.
The sensors' stainless steel construction helps guarantee compatibility with almost any chemical for plating. A ± 1.0 percent linearity (full scale) and ± 0.2 percent repeatability (full scale) provide accurate readings for critical applications. An analog 0 to 5 VDC output and pulse output are provided as standard and 4- to 20-mA outputs and an integrated display are optional.
