TFM4100 BROCHURE
The TFM4100-W Flowmeter works by measuring the “transit time” or “time of flight” for ultrasonic sound pulses transmitted from one transducer to another. Depending on the mounting configuration, the signal may cross the pipe once, twice or four mes. The me between transmitted and received signals is precisely measured by the flow meter. Ultrasonic signals are sent upstream and then down stream with the transducers alternating their functions as transmitters/receivers. The transit me in the direction of flow is always faster than the transit me against the flow. By comparing these differences with precision timing circuits, the TFM4100-W is able to accurately calculate the flow rate. Because the ultrasonic signal is forced to cross the pipe, an average of the flow profile is calculated. So compensation for laminar or turbulent flow is automatic.
