The larger the full bore magmeter, the higher the cost compared to the Signet 2552 Insertion Magmeter. As the pipe size increases, so does the price of the full bore spool piece. In addition to sensor costs, installation costs must be taken into consideration. When a pipe is full and under pressure, a full bore magmeter can only be installed if the line is shut down and a pipe section is cut out to make room for the full bore spool piece. See Chart #2 for price comparisions.
