The Sonney Orifice Flow 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.

  • 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
