Description
The King Instrument 7710 is an all-316L stainless steel metal-tube rotameter with a float and tapered-tube design that gives a long, linear 120 mm scale and ±3% of full scale accuracy. Full-scale ranges run from 33 GPH to 450 GPM of water (roughly 2 to 1,700 L/min) and 4 to 100 SCFM of air, in sizes from ½ to 4 in.
It is rated to 103 bar with NPT connections or to flange class ratings, and up to 204 °C depending on O-ring. The IP66 indicator can be fitted with a 4–20 mA transmitter and single or dual alarms.
