3 Function Measurement principle The transducers are mounted on the pipe which is completely filled with the fluid. The ultrasonic signals are emitted alternately by a transducer and received by the other. The physical quantities are determined from the transit times of the ultrasonic signals. The transmitter PIOX S determines physical quantities for analysis by using the transit time measurement and, additionally, physical quantities for flow by means of the transit time difference principle. Transit time measurement Path of the ultrasonic signal in the flowing fluid The average of the transit times of both ultrasonic signals in the fluid and the length of the sound paths in the fluid are used for the calculation of the sound speed. By using the average, the sound speed is independent of the flow velocity of the fluid. The physical quantities of analysis are determined from the sound speed. t γ Calculation of sound speed Average of transit times t γ in the flowing fluid c γ = l t --- where c γ - sound speed in the fluid l γ - sound path in the fluid t γ - Average of transit times in the fluid TSPIOX-S721SAV2-1-1EN_Leu,

4 Transit time difference principle Portable ultrasonic flow measurement of gas and liquids in hazardous areas The transit time difference, t, is measured and allows the flowmeter to determine the average flow velocity along the propagation path of the ultrasonic signals. A flow profile correction is then performed in order to obtain the area averaged flow velocity, which is proportional to the volumetric flow rate. Two integrated microprocessors control the entire measuring process. This allows the flowmeter to remove disturbance signals, and to check each received ultrasonic wave for its validity which reduces noise. t 0 t Calculation of volumetric flow rate V = k Re A k a t 2 t where V - volumetric flow rate k Re - fluid mechanics calibration factor A - cross-sectional pipe area k a - acoustical calibration factor t - transit time difference t γ - Average of transit times in the fluid Transit time difference t 4 TSPIOX-S721SAV2-1-1EN_Leu,

5 Number of sound paths The number of sound paths is the number of transits of the ultrasonic signal through the fluid in the pipe. Depending on the number of sound paths, the following methods of installation exist: reflection arrangement The number of sound paths is even. Both of the transducers are mounted on the same side of the pipe. Correct positioning of the transducers is easier. diagonal arrangement The number of sound paths is odd. Both of the transducers are mounted on opposite sides of the pipe. In the case of a high signal attenuation by the fluid, pipe and coatings, diagonal arrangement with 1 sound path will be used. The preferred method of installation depends on the application. While increasing the number of sound paths increases the accuracy of the measurement, signal attenuation increases as well. The optimum number of sound paths for the parameters of the application will be determined automatically by the transmitter. As the transducers can be mounted with the transducer mounting fixture in reflection arrangement or diagonal arrangement, the number of sound paths can be adjusted optimally for the application.. a a - transducer distance Reflection arrangement, number of sound paths: 2 a Diagonal arrangement, number of sound paths: 3 a > 0 a < 0 Diagonal arrangement, number of sound paths: 1 Diagonal arrangement, number of sound paths: 1, negative transducer distance TSPIOX-S721SAV2-1-1EN_Leu,
