Abstract
This paper describes the development, construction and experimental evaluation of a volumetric flow meter based on time of flight approach with reduced pressure drop. The prototype was designed aiming to use in a closed loop two-phase thermosyphon based on minichannels, hence, the flowmeter should present small pressure drop. The inlet and outlet channels have inner diameter of 4mm, and operates with liquid water. The prototype was built for less than R$200, and calibrated using the gravimetric process. The initial results indicate a mass flow meter with a high operational stability and reliability. The first tests indicate a precision of 5,7% for 3.6 to 36 L/min range.
