Sonney Orifice Computers

Sonney Orifice Computer

Is the industry standard for spot checking orifice metered flow rates. Easy to use and reliable it is still a ‘must have’ tool for every gas and oilfield production engineer, operator and supervisor. It is defined as a computer because it is in actuality a slide rule.

  • Features:
  • Supercompressibility (Fpv) correction is provided on the face of the computer.
  • Orifice diameters range from 1/16″ to 30″.
  • Delivery rates up to 1 billion cubic feet per day
  • Differential pressures from 0.1 to 200 inches of water for meter computations and 1 pound to 10,000 pounds for estimating flow through “chokes”.
  • Pressures from 29″ of mercury vacuum to 10,000 psi gauge.
  • Gravity correction — 0.1 to 1.5

Please note: the aluminum version of the Sonney is no longer available. Plastic is readily available.
