High-Pressure NPT Flowmeters

The HO series of high-pressure turbine flowmeters for liquid-flow applications handles pressure ranges from 2,000 to 5,000 psi. The 316 stainless-steel flowmeters from Hoffer Flow Controls Inc., Elizabeth City, N.C., feature NPT configuration. They have a 0.2 to 800-gpm flow range and come in 0.25 to 3-in. sizes. They feature linearity ±0.5% of reading over the linear flow range and repeatability of ±0.1% over the usable range with a 10:1 to 100:1 turndown.
