The advantages of ultrasonic flow meters is measurement without pressure drop. In this article an ultrasonic flow meter based on transit time measurement by Heterodyne technique is designed and fabricated. The principles of the flow meter, selection procedure of transmitter and receiver transducers and the excitation frequency of those are presented. A closed loop pipeline has been designed in order to test the flow meter. The results present that the flow measurement in range of 22 up to 37 Liter per second contain errors in range of -2.7 up to +4.2 present of actual flow.
