ABSTRACT:
A metering system for measuring a flow of petroleum and LPG. In embodiments of the invention, a magnetic drive is used to couple a measuring chamber, such as a known oscillating piston system, to a register or indicator, avoiding leakage and excessive wear due to passing a shaft through the wall of the chamber.
