Description
The King Instrument 7330 Series is a variable-area flow meter (rotameter) with a moulded polysulfone metering tube and PVC or PVDF union ends. It covers water flows from 0.5 GPM up to 160 GPM depending on the float, reads directly on a 5 in detachable scale, and gives ±3% of full scale accuracy with 10:1 turndown.
With a Teflon float and PVDF fittings it can be built with no wetted metal for corrosive liquids, and internals are also available in 316L SS or Hastelloy C-276. It is rated to 150 psig in the smaller sizes, up to 93 °C with PVDF fittings, and can be fitted with a latching reed-switch alarm.
