Iluphi uhlobo lwe-flowmeter oluphakamisa ukuthi lusetshenziselwe amanzi ahlanzekile?
2022-07-19
Kunezinhlobo eziningi ze-flowmeters ezingasetshenziswa ukukala amanzi ahlanzekile. Kumele kuqashelwe ukuthi amanye ama-flowmeters awakwazi ukusetshenziswa, njengama-flowmeters kagesi. I-electromagnetic flowmeters idinga ukuthi ukuqhutshwa kwendawo okuphakathi kube kukhulu kuno-5μs/cm, kuyilapho ukuqhutshwa kwamanzi ahlanzekile akukwazi ukusetshenziswa. ukufeza izidingo. Ngakho-ke, i-flowmeter ye-electromagnetic ayikwazi ukusetshenziswa ukukala amanzi ahlanzekile.
Imitha yokugeleza kwe-turbine ewuketshezi, amamitha okugeleza kwe-vortex, amamitha okugeleza kwe-ultrasonic, ama-flowmeters amaningi e-coriolis, ama-rotameter eshubhu lensimbi, njll. konke kungasetshenziswa ukukala amanzi ahlanzekile. Kodwa-ke, ama-turbines, imigwaqo ye-vortex, amapuleti e-orifice namanye amapayipi aseceleni konke kunezingxenye eziminyanisayo ngaphakathi, futhi kukhona ukulahlekelwa kwengcindezi. Uma kuqhathaniswa, ama-flowmeters e-ultrasonic angafakwa ngaphandle kweshubhu njenge- clamp ohlotsheni, ngaphandle kwezingxenye eziklinyiwe ngaphakathi, futhi ukulahlekelwa kwengcindezi kuncane. I-mass flowmeter ingenye yalawa ma-flowmeters anokulinganisa okuphakeme kakhulu, kodwa izindleko ziphezulu.
Ukucatshangelwa okuphelele kufanele kucatshangelwe lapho ukhetha. Uma kuphela izindleko zicatshangelwa futhi imfuneko yokunemba ayiphezulu, i-glass rotor flowmeter ingakhethwa. Uma izindleko zingacatshangelwa, ukunemba kwesilinganiso kuyadingeka ukuthi kube phezulu, futhi imitha yokugeleza kwenqwaba ingasetshenziselwa ukuxazululwa kohwebo, ukulinganisa kwezimboni, njll. Uma kucatshangelwa ngokusesilinganisweni, ama-flowmeters e-turbine ewuketshezi, ama-vortex flowmeters, nama-flowmeters e-ultrasonic angasetshenziswa. . Ilinganisa ngokunemba kwesilinganiso kanye nezindleko, futhi ingahlangabezana nezidingo eziningi zensimu.
