Description
The King Instrument 7100 is an all-316L stainless steel rotameter for low flows at high pressure, with full-scale ranges from 2.4 to 95 L/h of water or 28 to 3,400 SL/h of air. It reads to ±5% of full scale with 1% repeatability and 10:1 turndown on a 60 mm direct-reading scale.
With ¼ in FNPT connections it is rated to 276 bar (103 bar with valve), or it can be flanged, and with suitable O-rings it handles up to 204 °C. Options include integral control valves, Hastelloy internals, an inductive alarm and certified calibration.
