Pipeline Sphere – UniCast Sphere Setting a New Standard

Meter Engineer’s UniCast Sphere is a seamless, inflatable meter proving and pipeline sphere that has reset the standard in accuracy and durability which has become the industry’s first choice.

Seamless Construction
The seamless exterior of Meter Engineer’s UniCast Sphere is molded into one inflatable continuous shell of polyurethane that prevents splitting and retains its “Sphericity.” While other two-piece meter prover spheres can inflate into an egg-shape, our one-piece construction helps the sphere to maintain a truer diameter, giving a more accurate measurement.

Two Weights
Our UniCast Sphere comes in two weights, Standard and Heavy. The standard weight UniCast Sphere is ideal for normal operations while the heavyweight UniCast Sphere should be utilized in high turbulence applications. In the weighted UniCast spheres, the weight is cast into the internal bladder, which will help contain the weight in the event of a catastrophic destruction of the sphere.

Diameters & Durometers | UniCast Spheres | Pipeline Sphere
We manufacture the UniCast Sphere in three durometers and multiple diameters to fit any application. We can also customize our formulas for any special application you may have.

  • 50 Series (55 durometer) Yellow
  • 60 Series (60 durometer) Green
  • 70 Series (70 durometer) Red

Low Friction
MEI offers a low friction sphere for dry, non-lubricating products to reduce sphere chatter. Tests have shown a 38% reduction of friction with this product.

Accessories
