Te hītori whanaketanga o te mita rere tere-rohe mai i Lanry

Ko tā mātou mita rere tere rohe he momo taputapu rere i roto i te awa tuwhera me te paipa kua kī katoa. He pai te mita rere Tere-Area Doppler hei tatau i te rere, te tere rere me te ine taumata mō ngā momo wai katoa (mai i te iti o te paru ki te tino paru) mā te ine ultrasonic me te ine pēhanga. Kei roto i te paipa te ine, ā, kei raro hoki i te awa tuwhera.

He pai te mahi a te mita rere wai tere rohe i runga i ngā awa tuwhera mō te maimoatanga wai para, te pūoko rere para, ngā whare maimoatanga wai para ahumahi me te whakamakuku ahuwhenua, te aroturuki taiao, te aroturuki rere me te wai ua, te wai whenua, me ētahi atu.

Mō te mita rere doppler o te hongere tuwhera, ehara i te mea ko te mita rere doppler paipa katoa, kei raro nei ōna painga:

1. Kāore e hiahiatia he awaawa, he pā rānei, ā, he ngāwari te tāuta;

2. Whakaaturanga LCD tae 4.5 inihi me te akomanga tiaki Ip68, ka taea te whakaatu pai i te tere rere, te tere, te whakakī i te taumata me ētahi atu mōhiohio whai hua mā te whakaaturanga LCD;

3. He uara ine pai rawa atu o te taumata wai, te kawe hiko, te rere me te tere rere;

4. Mita rere ultrasonic mahi taki raraunga mō te aroturuki me te pūrongo raraunga;

5.

Ko te whanaketanga o te mita rere tere rohe ultrasonic penei i raro nei:

I te tau 1996, i whakarewahia e mātou te pūoko rere doppler QSD6526 o te whakatipuranga tuatahi.

Ka taea e te mita rere ultrasonic Doppler te ine i te tere rere o te wai me te taumata wai mā te pūoko pēhanga.

Te taputapu rere doppler tere rohe me ngā hanganga piri

1. Ko te awhe tere rere kei waenganui i te 21mm/s ki te 4500mm/s

2. Ko te awhe ine taumata kei waenga i te 0 ki te 2m me te 0 ki te 5m.

3. Ko te tika he 2%

I te tau 2014, i whakarewahia e mātou te mita o te whakatipuranga tuarua: te pūoko rere doppler QSD6527.

Ko te mahi hou o te mita rere oro-oro tere rohe penei:

1. Ka inehia te taumata wai mā te pūoko ultrasonic, kaua mā te pūoko pēhanga;

2. Ka whakamahia he hoahoa tinana hiri-epoxy, ā, ka taea te whakatutuki i te ine rere wai e rua-ara;

I te tau 2018, i whakarewahia e mātou te putanga hou o te aroturuki rere doppler tere rohe: te pūoko rere doppler QSD6537.

1. Tāpirihia te mahi ine i te kawe hiko;

2. Ka taea te ine i te taumata o te wai mā roto i ngā tikanga e rua: te pūoko ultrasonic me te pūoko pēhanga;

3. Tāpirihia te mahi o te pēhanga hau me te pāmahana;

4. Kei roto i tēnei mita te hangarau doppler DSP mamati, kaua ki te hangarau doppler whaihanga. Ko te tika he ±1%;

5. Ko te awhe tere rere o tēnei mita kei waenga i te 20mm/s ki te 12 m/s;

6. Ko te awhe taumata he 20mm ki te 5m mā te pūoko ultrasonic me te 0mm ki te 10mm mā te pūoko pēhanga;

7. Ka taea e tēnei mita hou te ine i ngā wai ma;

8. Ka tāpirihia e te pūwero te putanga Modbus RTU;
