Xyoo 1996, peb tsimthawj tiam: thaj tsam tshaj tawm sensor hu ua QSD6526 sensor .
Nws ua haujlwm ntawm ultrasonic doppler txoj cai, nws tuaj yeem ntsuas tus nqi ntws los ntawm ultrasonic sensor thiab qib kua los ntawm lub siab sensor;
Nws yog glued lug;
Kev khiav ceev: 21mm / s txog 4500mm / s;
Qhov tob: 0-2m thiab 0-5m.
Qhov tseeb: 2%
Hauv 2014, qhov thib obtiamntawm thaj tsam tshaj tawm sensor: QSD6527 sensor yog tsim.
Peb hloov txoj kev ntsuas kua los ntawm ultrasonic sensor es tsis txhob siab sensor;
Nws txais Epoxy ib qho potting tshuab;
Bidirectional ntsuas peev xwm.
Hauv 2018, lub cim thib peb ntawm thaj chaw tshaj tawm sensor: QSD6537 sensor tau raug tso tawm.
Ua kom muaj kev ua haujlwm siab, siab thiab ultrasonic sensor ob txoj hauv kev ntsuas cov kua theem, nce qhov kub thiab txias, kev them nyiaj siab, ntsuas ntsuas analog rau cov teeb liab ntsuas, qhov tseeb tau nce mus rau 1%;
Flow tus nqi: 20mm / s txog 12m / s;
Ua kua theem ntau: 20mm mus rau 5m ultrasonic;0mm-10m siab;
Koj tuaj yeem ntsuas cov kua dej ntshiab;
Sensor nrog ntxiv modbus RTU tso zis;
Ib qho kev siv thev naus laus zis loj tau ua tiav.
