The two Meter Prover grades are fine tolerance spheres for guaranteed roundness. Spheres are manufactured in a hardness range of 35 to 80 Shore A, determined by the application and internal finish of the pipeline. Inflatable spheres incorporate an integrated Shraeder valve(s) moulded into the wall of the sphere. The valves are easily removed and replaced. A sealing cap can be fitted to the valve housing to prevent ingress of line pressure into the sphere. Traverse Spheres can be used in unidirectional or bi-directional pipelines and will pass most full bore fittings except gate valves. Where the side branch on tees is greater than 25% of the pipeline diameter, the use of a Sphere Flow Tees is recommended. Configurations Solid spheres are available in standard sizes between 1½” and 8”, and inflatable spheres from 3” to 48”. Spheres can be weighted or have magnets embedded and are available in FDA approved polyurethane for Food Industry and in Potable Water Systems. General function and application: Our range of solid and inflatable spheres is used for product separation, liquid evacuation and in Meter Provers. are particularly useful as an interface between different grades of product in automatic or remote systems where the spheres are launched under computer control.
