Description
The King Instrument 7310 Series is a rotameter with a moulded polysulfone tube enclosed in an economical 304 stainless steel case with a polycarbonate shield, for lighter-duty water and air applications where a cased meter is preferred. Water ranges run from 0.5 to 160 GPM and air ranges from 6.1 to 330 SCFM, read on a 5 in direct-reading scale.
Accuracy is ±3% of full scale with 10:1 turndown. With standard 316L SS fittings it is rated to 200 psig and 93 °C, and PVC or PVDF fittings, Hastelloy internals and a latching reed-switch alarm are available.
