Patent ID: 7484404

Claim:
A system for vaporizing and measuring liquid gas, the system comprising: a transmission device operable to transmit liquid gas; a measurement device operable to continuously extract at least a portion of the liquid gas from said transmission device while it is being transmitted by said transmission device, convert the extracted liquid gas from liquid form to vapor form and determine the constituent components of the vapor gas, wherein said measurement device comprises: a first stage vaporizer operable to receive a first amount of liquid gas and convert the first amount of liquid gas into vapor gas; a second stage vaporizer operable to receive a second amount of liquid gas and convert second amount of liquid gas into vapor gas; an accumulator connected to said first and second stage vaporizers and operable to receive and store the vapor gas; and a third stage vaporizer connected to said accumulator and operable to receive stored vapor gas from said accumulator and heat the received vapor gas to within a desired temperature range.
