Ngonyaka we-1996, savelisaisizukulwana sokuqala: Isivamvo sesantya sendawo esibizwa ngokuba yi-QSD6526 sensor.
Isebenza kumgaqo we-doppler we-ultrasonic, inokulinganisa izinga lokuhamba nge-sensor ye-ultrasonic kunye nenqanaba le-liquid nge-sensor yoxinzelelo;
Izakhiwo ezincamatheleyo ;
Isantya sokuhamba: 21mm/s ukuya kwi-4500 mm/s;
Uluhlu lobunzulu: 0 ukuya ku-2m kunye no-0 ukuya ku-5m.
Ukuchaneka : 2%
Ngo-2014, okwesibiniisizukulwanaIsivamvo sesantya sendawo: inzwa ye-QSD6527 iveliswa.
Sitshintshe indlela yokulinganisa ulwelo ngenzwa ye-ultrasonic endaweni yenzwa yoxinzelelo;
Yamkela itekhnoloji yokubumba i-Epoxy edibeneyo;
Isakhono somlinganiso omacala omabini .
Ngo-2018, isizukulwana sesithathu senzwa yesantya sendawo: QSD6537 sensor ikhutshiwe.
Ukwandisa umsebenzi we-conductivity, uxinzelelo kunye ne-sensor ye-ultrasonic iindlela ezimbini zokulinganisa inqanaba le-liquid, ukwandisa imbuyekezo yeqondo lokushisa, imbuyekezo yoxinzelelo, ukulinganisa umqondiso we-analog kumlinganiselo wesignali yedijithali, ukuchaneka kwanda ukuya kwi-1%;
Uluhlu lwezinga lokuhamba: 20mm / s ukuya kwi-12m / s;
Uluhlu lwenqanaba lolwelo: 20mm ukuya kwi-5m ultrasonic;0mm ukuya kwi-10m uxinzelelo;
Ungalinganisa ulwelo olusulungekileyo ngokwentelekiso ;
Isivamvo esinemveliso eyongeziweyo ye-modbus RTU;
Kuye kwaphunyezwa impumelelo enkulu kwezobuchwepheshe .
