Ngonyaka ka-1996, sakhiqizaisizukulwane sokuqala: inzwa yesivinini sendawo ebizwa nge-QSD6526 sensor.
Isebenza kumgomo we-doppler we-ultrasonic, ingakwazi ukukala izinga lokugeleza ngenzwa ye-ultrasonic kanye nezinga le-liquid ngenzwa yokucindezela;
Kuyinto izakhiwo ezinamathiselwe;
Isivinini sokugeleza: 21mm/s kuya ku-4500 mm/s;
Ukujula kwebanga: 0 kuya ku-2m no-0 kuye ku-5m.
Ukunemba : 2%
Ngo-2014, okwesibiliisizukulwaneinzwa yesivinini sendawo: Inzwa ye-QSD6527 ikhiqizwa.
Sishintshe indlela yokulinganisa uketshezi ngenzwa ye-ultrasonic esikhundleni senzwa yokucindezela;
Yamukela ubuchwepheshe be-Epoxy integral potting;
Ikhono lokulinganisa le-Bidirectional .
Ngo-2018, isizukulwane sesithathu senzwa yesivinini sendawo: Inzwa ye-QSD6537 ikhishwe.
Ukwandisa umsebenzi we-conductivity, ingcindezi kanye nenzwa ye-ultrasonic izindlela ezimbili zokulinganisa izinga le-liquid, ukwandisa isinxephezelo sokushisa, isinxephezelo sokucindezela, ukulinganisa isignali ye-analog ekulinganisweni kwesignali yedijithali, ukunemba kukhuphuke ku-1%;
Ibanga lesilinganiso sokugeleza :20mm/s kuya ku-12m/s;
Ibanga lezinga likaketshezi :20mm kuya ku-5m ultrasonic;ingcindezi 0mm kuya 10m;
Ungakwazi ukukala uketshezi olumsulwa ngokuqhathaniswa;
Inzwa enokukhishwa kwe-modbus RTU eyengeziwe;
Kwafinyelelwa impumelelo enkulu kwezobuchwepheshe .
