FL-1300 Series rotameters are
supplied with an easy-to-read
65 mm (2.6") scale. The
FL-1400 Series features a large,
easy-to-read 150 mm (5.9") scale,
with correlation charts for air and
water. The integral flow controller
(for both the FL-1300 and FL-1400
Series) maintains a set flow rate
when upstream line pressure varies.
