Abstract
Apparatus comprising an interchange which receives a sphere from a meter prover loop after a meter prover run and which launches the sphere into the loop to commence a run. An assembly within the body of the interchange is movable between sphere receiving and sphere launching positions. When in sphere launching position it provides a seal which prevents flow through the interchange. Means is incorporated which prevents hydraulic shock when the assembly is moved from sphere receiving to sphere launching position. Also the apparatus has improved means for detecting leakage.
