Hoffer HO for Liquid Service

• Available turn down range is 10:1 to 100:1
• Linearity of ± 0.5% of reading (±0.25% typical) over tabulated linear flow range.
• Repeatability of ± 0.1% (±0.05% typical) over tabulated linear repeatable flow range.
• Temperature range: -450°F to + 450° F standard. There is a high temperature option to +850°F, dependent upon flowmeter configurations.
• Pressure drop characteristics 4 to 5 PSI at maximum linear flow rate at one CSTK.
• End fittings are NPT, MS flared and flanged styles.
• Bearing Styles: Ceramic hybrid ball bearings and sleeve bearings in tungsten carbide and hard carbon composite are available.

Hoffer HO for Gas Service

• Available turn down range is dependent upon gas density and operating conditions.
• Linearity of ± 1% of reading typical (each meter’s reading is dependent upon density).
• Repeatability of ± 0.25% over tabulated linear flow range.
• Temperature range: -450° F to + 350° F continuous (to + 450° F intermittent heat). Also depends on bearing/coal selection.
• End fittings of MS flared and flanged styles are recommended.
