<p>A well watchman pumping and control system capable of operating in a wide range of ambient conditions is described. The system automatically maintains fluid level in a fluid storage vessel, while protecting the pump and generator from operating in conditions outside preset operating parameters to prevent premature failure and reduce repair. By operating to pump fluid only when preset operating conditions exist, e.g. low fluid level, ambient temperature, etc., the system reduces labor, fuel, and maintenance operating costs to the owner, improves well pumping reliability and production, reduces generator fuel consumption, reduces emissions, and conserves ground water or liquid hydrocarbons, whichever is being pumped into the fluid storage vessel by the system.</p> |
