HO SERIES Turbine Flowmeters for Gas Service

The Turbine Flowmeter Company

Product Bulletin HO-G-110F

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.

SPECIFICATIONS

Available Temperature Range: Overrange: 150% of maximum flow (intermittently). -450°F to +350°F continuous (to +400°F intermittent heat). Available Turn Down Range: Dependent on gas density at user‘s operating conditions. End Fittings: MS flared and flanged styles are recommended. Other types available on request. Linearity: ±1% of reading typical. *** Bearing Styles: Ceramic hybrid ball bearings only. Repeatability: ±0.25% over tabulated repeatable range. Materials: 316 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.

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.
