Xyoo 1996, peb tau tsimthawj tiam neeg: thaj chaw ceev sensor hu ua QSD6526 sensor.
Nws ua haujlwm ntawm ultrasonic doppler txoj cai, nws tuaj yeem ntsuas qhov ntws los ntawm ultrasonic sensor thiab kua theem los ntawm lub siab sensor;
Nws yog cov qauv nplaum;
Qhov ceev ntws: 21mm/s txog 4500 mm/s;
Qhov tob: 0 txog 2m thiab 0 txog 5m.
Qhov tseeb: 2%
Xyoo 2014, qhov thib obtiam neegntawm thaj chaw ceev sensor: QSD6527 sensor yog tsim tawm.
Peb tau hloov txoj kev ntsuas kua los ntawm lub sensor ultrasonic es tsis yog lub sensor siab;
Nws txais yuav Epoxy integral potting technology;
Muaj peev xwm ntsuas ob txoj kev.
Xyoo 2018, tiam thib peb ntawm thaj chaw ceev sensor: QSD6537 sensor tau raug tso tawm.
Ua kom muaj kev ua haujlwm conductivity, siab thiab ultrasonic sensor ob txoj hauv kev los ntsuas qib kua, ua kom qhov kub thiab txias them rov qab, siab them rov qab, ntsuas teeb liab analog rau ntsuas teeb liab digital, qhov tseeb nce mus txog 1%;
Tus nqi ntws ntau yam: 20mm / s txog 12m / s;
Qib kua ntau yam: 20mm txog 5m ultrasonic; 0mm txog 10m siab;
Koj tuaj yeem ntsuas cov kua dej uas huv si;
Sensor nrog ntxiv modbus RTU tso zis;
Ib qho kev tshawb pom tseem ceeb ntawm thev naus laus zis tau ua tiav.
