Spheres & Accessories
UniCast Spheres Overview
Making Accuracy Seamless
The UniCast Sphere is a seamless, inflatable meter proving sphere with enhanced durability and unwavering precision. Each sphere features a design optimized for elasticity, wear-resistance, and operational lifetime, eliminating seam splitting and delaminating during service. Along with our exceptional factory support, our spheres have become ubiquitous in the Petroleum industry globally and the first choice for accuracy.
Features at a Glance
The unified exterior of the UniCast Sphere is molded into one inflatable continuous shell of polyurethane that prevents splitting and retains its “Sphericity.” While other two-piece spheres can inflate into an egg-shape, our one-piece construction helps the UniCast Sphere maintain a truer diameter, giving the most 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 spheres, the weight is cast into the internal bladder, which will help contain the weight in the event of the catastrophic destruction of the sphere.
Low Friction
Offering 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
We have several sphere accessories to aid with inflation and handling during routine maintenance and/or replacement.

Sphere sizing rings are custom machined from lightweight .250 aluminum plate to customer specified sizes, allowing operators to check and reproduce the proper inflation size of the sphere. Rings are typically sized for 2% – 4% larger than the inside diameter of the pipe size. Sphere rings are available for all sizes of spheres.
