Umgaqo wokusebenza weDoppler
IDF6100Uchungechunge lwe-flowmeter lusebenza ngokusasaza isandi se-ultrasonic ukusuka kwi-transducer yokuhambisa, isandi siya kubonakaliswa zizibonisi eziluncedo ze-sonic ezixhonywe ngaphakathi kolwelo kwaye zirekhodwe yi-transducer eyamkelayo.Ukuba izibonisi ze-sonic zihamba ngaphakathi kwendlela yokuhambisa isandi, amaza omsindo aya kubonakaliswa kwi-frequency shifted (i-Doppler frequency) ukusuka kwi-frequency transmitted frequency.Ukutshintshwa kwi-frequency kuya kuhambelana ngokuthe ngqo kwisantya se-particle ehambayo okanye i-bubble.Olu tshintsho lokuphindaphinda lutolikwa sisixhobo kwaye luguqulelwe kwiiyunithi ezahlukeneyo zokulinganisa ezichazwe ngumsebenzisi.
Kufuneka kubekho amasuntswana amakhulu ngokwaneleyo ukuze abangele ukubonakaliswa kwe-longitudinal - amasuntswana amakhulu kune-100 micron.
Xa ufaka ii-transducers, indawo yofakelo kufuneka ibe nobude obaneleyo bombhobho othe ngqo phezulu nasezantsi.Ngokuqhelekileyo, i-upstream ifuna i-10D kunye ne-downstream idinga ubude be-5D obuthe ngqo bombhobho, apho i-D iyidayamitha yombhobho.
