HOFFER Perfecting Measurement BEST TURBINE IN THE INDUSTRY 5-YEAR WARRANTY HO SERIES Turbine Flowmeters for Gas Service Product Bulletin HO-G-111L TECHNICAL DATA SHEET OUTSTANDING FEATURES Low cost. Outstanding accuracy. Provides wide flow ranges. Wide variety of process connections available.* Operate over a wide range of temperatures and pressures. Exclusive use of hybrid ceramic ball bearings provide superior life. *MS Flared or Flanged end connections are best suited due to the even transition at the connections. Flowmeter Size Diameter (inches) 1/2 x 1/4 1/2 x 3/8 5/8 3/4 1 1¼ 1½ 2 2½ 3 4 5 6 8 10 12 SPECIFICATIONS Overrange: 150% of maximum flow (intermittently). Available Turn Down Range: Dependent on gas density at user‘s operating conditions. Linearity: ±1% of reading typical. *** Repeatability: ±0.25% over tabulated repeatable range. Note: Performance enhancement techniques are routinely applied to produce wider linear and useable flow ranges. This technique is also used to improve linearity and repeatability. Consult the applications group at Hoffer with your requirements. Available Temperature Range: -450°F to +350°F continuous (to +400°F intermittent heat). Dependent on bearing/coil selection. End Fittings: MS flared and flanged styles are recommended. Other types available on request. Bearing Styles: Self-lubricating, ceramic hybrid ball bearings. Materials: 316/316L dual rated stainless steel standard. Consult with applications group for corrosive applications. Broad material list available. ***Linearity is density-dependent for a given meter. Consult factory for details.
