Patent ID: 7263459

Claim:
A method of measuring a reading at a remote location on a hydrocarbon process line, the method comprising: at said remote location collecting a first analog reading with a first sensor; converting the first analog reading to a first digital reading; collecting the first digital reading from said first sensor in a control means for receiving, processing, and storing the processed digital reading, wherein said control means is located at said remote location; correcting said processed digital readings for temperature effect corruption by mapping the processed digital readings to a temperature value in an iterative fashion; and, back calculating to an adjusted pressure and an adjusted temperature; storing the processed digital readings at the remote location until the processed digital reading can be transferred to a modem communications means for communicating digital data, wherein said modem communications means is located at said remote location; converting the processed digital reading to a digital packet data in the modem communications means; transmitting the digital packet data with the modem communications means; at a central location remote from the remote location receiving the digital packet data at a database engine located at the central location; and providing a web server interface in the database engine; linking the database engine to the Internet; providing a user computer, said user computer having a web browser; communicating to the Internet; accessing the database engine; monitoring the processed digital reading from said user computer.
