WIC-II
WIC-II

The Automation and Electronics, Inc. Water Injection Controller (WIC-II) is designed to monitor and control the injection of water at the wellhead and to monitor gas pressure and solar battery voltage levels. User configurable pressure and flow test programs are provided.

The WIC-II unit was developed specifically for injection well monitoring and control for oil field operations. It is fully configurable by the operator using an optional local interface, Personal Digital Assistant or portable computer. The unit is supplied with typical parameters ready for specific application tuning. Setup parameters may also be downloaded from a host computer. Software lockout notification provided by host and local interface.
