14. 2 2 Transit time difference AT Because the medium in which the signals propagate is flowing the transit time of the sound signals propagating in the direction of flow is shorter than the transit time of the signal propagating against the direction of flow The transit time difference AT is measured and allows the determination of the average flow velocity on the propagation path of the ultrasonic signals A profile correction is then performed to obtain the average flow velocity on the cross section of the pipe which is proportional to the volume flow rate EESIFLO tests with its special electronics the incoming ultrasonic signals for their usefulness for the measurement and evaluates the plausibility of the measured values The integrated microprocessors control the complete measuring cycle eliminating disturbance signals by statistical signal processing techniques 2 3 Applications EESIFLO can be used everywhere where the pipe wall and the liquid to be measured are sonically conductive This is true for pipe walls consisting of homogeneous material and for liquids which carry only small amounts of solid particles or gas bubbles Since ultrasonic waves also propagate in solid materials the transducers can be mounted outside the pipe allowing for non invasive measurement The transit time difference effect can be observed over the complete range of flow velocities found in technical applications Furthermore it is independent of the elec
