DefinitionA <TIME OF FLIGHT ULTRASONIC FLOW METER> is an <INSTRUMENTATION ITEM> and a <VOLUME FLOW MEASURING INSTRUMENT> that handles the measurement results of a <VOLUME FLOW MEASURING ELEMENT - ULTRASONIC TRANSIT TIME>
Two transmitters / receivers (transceivers) are located on each side of the pipe. The transmitters sends pulsating ultrasonic waves in a predefined frequency from one side to the other. The difference in frequency is proportional to the average fluid velocity.
