ABSTRACT:
An electronic valve controller for controlling a meter valve system is disclosed. The electronic controller includes circuitry for enabling a multilevel shutdown of a meter valve system. The meter valve system includes a preset batch counter, positive displacement meter and diaphragm operated globe valve. The electrical circuitry is operatively associated with the meter valve system in enhancing and inhibiting the flow through the globe valve based upon a comparison of a preset desired flow rate and the actual system flow rate.
