the major benefits of heated tube mass flowmeters. The addition of an electromagnetically controlled automatic valve turns the meter into a mass flow controller, ideal for any application where mass (as opposed to volumetric) flow rate control is desired. The only requirement for this type flowmeter is that the fluid should be

Increasing the fluid mass flow rate of the main stream enabled the two heat exchangers to be fully utilized and improved the overall heat transfer efficiency. The temperature of the cold fluid in the bypass was greatly increased after being heated by DFBR, which reduced the average temperature difference of EHE and heat transfer efficiency.
