The King Instrument 7330 series flowmeter is excellent for applications where no metal is preferred. Series 7330 offers the following scale ranges; 0.5 to 100 GPM with Teflon float (water) and 1.5 to 160 GPM (water) with metal float. Accuracy is ± 3% of full scale flow, ± 5% of full scale flow for 120 & 150 GPM metal floats and ± 6% of full scale flow for Teflon floats. Turndown is 10:1. Repeatability for 120 & 150 GPM metal floats and Teflon floats is 1%, everything else is 1/2%. Series 7330 has a standard Viton O-ring with optional Buna-N, EPR and Kalrez offerings.
