Abstract:
A vent assembly for a double case, rotary positive displacement meter permits venting of the outer housing chamber and inner mechanism chamber simultaneously through a single port in the outer housing to prevent damage to the rotor of the inner mechanism. A float/reed switch assembly can be provided to provide an indication of the need for venting if the vent is manually operated, or to automatically vent if an electrically operated valve is used.
