Wafer-Cone Flow Meter - the Fast-change Replacement

Engineers with small line size processes rely on the versatile Wafer-Cone Flow Meter for superior accuracy and repeatability. The space-saving unit is easy to install. It’s ideal for tight-space installations and retrofits. It requires almost no maintenance. The Wafer-Cone further reduces life-cycle costs with a long life.

The Wafer-Cone flow meter uses the same revolutionary principles as the V-Cone. Its self-conditioning means little or no upstream or downstream piping runs are required.

The Wafer-Cone features a flangeless design. The element is easily replaced to accommodate changing flow conditions. Recalibration is not required. There are no moving parts to maintain. The unit combines exceptional flexibility with high performance.

 

Key features include:

• No straight pipe runs
• Maximum flexibility
• Economical
• Accuracy to +/- 0.5%
• Repeatability to 0.1%
• Machineable in any material
• No moving parts, low maintenance

How Wafer-Cone Works
The Wafer-Cone works on the same operating principle as the V-Cone. It is a differential pressure type flow meter with a unique design that conditions the flow prior to measurement.

• Differential pressure is created by a cone placed in the center of the pipe.

• The cone is shaped so that it “flattens” the fluid velocity profile in the pipe, creating a more stable signal across wide flow downturns.

• Flow rate is calculated by measuring the difference between the pressure upstream of the cone at the meter wall and the pressure downstream of the cone through its center.

Wafer-Cone Specifications
The Wafer-Cone is an advanced differential pressure flow meter, similar to the V-Cone but offering greater installation flexibility and economy.

Specifications and design features:

• Standard Accuracy: From +/-1.0% of actual flow (certain fluids and Reynolds number applications require specific calibrations to achieve this value).
• Repeatability: +/-0.1% or better
• Flow Ranges: 10:1 and greater
• Standard Beta Ratios: 0.45 to 0.85, special betas available
• Head Loss: Varies with beta ratio and DP
• Installation Piping Requirements: Typically 1-3 diameters upstream and 1 diameter downstream of the cone are required, depending on fittings or valves in the adjacent pipeline.
• Materials of Construction Include: 304 or 316 stainless steel; special materials on request.
• Line sizes: 1" to 6"
• Process Connection: Flangeless: no welding on pressure body
• Calibrated for customer application
• ASME B31.3 construction available
• Interchangeable cone elements for different flow ranges
• Sized and fluid calibrated for customer application
• No-moving parts
• No welding on pressure vessels
• Options: gas or oil flow calibration
