Abstract
A fluid volume flow monitoring apparatus, fluid volume flow monitoring system and process of monitoring fluid volume flow are disclosed. The fluid volume flow monitoring apparatus includes a support member having a distal end, a proximal end, and an outer wall with a first temperature sensing means for sensing fluid temperature positioned on the support member outer wall. A second temperature sensing means is positioned apart from the first temperature sensing means and juxtaposed to a generally tubular heat transfer device which is radially disposed about the support member outer wall. The heat transfer device directly contributes to the ability of the monitor to determine continuously fluid volume flow and includes an electrically insulated heating means positioned between a temperature equilibrator and an insulating material.
