A controller system for a flowing gas well utilizing battery powered solid state production and cycle time-out circuitry. In addition to expanded cycle interval capabilities, the system permits a broad range of automated controls over well production through the continuous monitoring of and reaction to such parameters as casing pressure, tubing string pressure, plunger elevation, sales line pressure and flow rate, as well as liquid level monitoring within separation and storage facilities. The solid state circuitry incorporates such features as liquid crystal readout, battery voltage level monitoring and automatic reset at the commencement of each timing cycle. Motor valve actuation is provided by electromagnetic actuation of a controller mounted shuttle piston valve.
