DEVICES AND METHODS FOR LANDFILL GAS WELL MONITORING AND CONTROL |
摘要 |
A landfill well control system includes a mobile hand-held device provided with a software monitoring application including a table having data related to determination of a desired methane gas output flow rate. A landfill gas (LFG) wellhead gas control valve includes: an electronically controlled, powered flow control device actuator; a flow measurement element producing differential pressures proportional to a gas flow rate; a pressure sensor/transducer; and a microprocessor having control logic capability and the ability to communicate via a local wireless signal to the mobile hand-held device. The powered flow control device actuator using data from the table of the mobile hand-held device or remotely stored data provides automatic valve positioning. |
