摘要： A small volume prover apparatus and method for precisely measuring the displaced volume of a fluid. A precision bore cylinder and a piston can be configured with a valve arrangement in order to permit fluid to pass through an annular passage when the piston travels from one position to an opposite position. A magnetized forcer connected to the piston and a magnetic drive chamber configured to produce linear motion of said magnetized forcer are operably connected to the piston in order to move the piston from one position to the other.
