Tarihin ci gaban mitar kwararar ruwa mai saurin yanki daga Lanry

Mita kwararar gudu ta yankinmu nau'in kayan aikin kwarara ne a cikin tashar buɗewa da bututun da aka cika da wani ɓangare. Mita kwararar Doppler ta yanki-gudu tana da kyau don ƙididdige kwarara, ƙimar kwarara da ma'aunin matakin kowane nau'in ruwa (daga ƙaramin ruwa mai datti zuwa mai datti sosai) ta hanyar na'urar bincike ta ultrasonic da na'urar matsi. An sanya na'urar binciken a cikin bututun da kuma ƙasan tashar buɗewa.

Mita mai auna gudu na ruwa a yankin yana aiki sosai a kan hanyoyin buɗewa don maganin ruwan shara, na'urar gano kwararar ruwa, wuraren sarrafa ruwan sharar masana'antu da ban ruwa na noma, sa ido kan muhalli, kwararar ruwa mai tasiri da na'urar lura da ruwan sama, ruwan ƙasa, da sauransu.

Ga ma'aunin kwararar doppler mai buɗewa ba tare da cikakken bututu ba, yana da fa'idodi masu zuwa:

1. Ba ya buƙatar wani bututun hayaƙi ko kuma mai sauƙin shigarwa;

2. Nunin LCD mai launi inci 4.5 da kuma aji na kariya na Ip68, zai iya nuna daidai yadda kwararar ruwa, saurin gudu, jimillar bayanai, matakin da sauran bayanai masu mahimmanci ta hanyar nunin LCD;

3. Kyakkyawan ƙimar aunawa na matakin ruwa, gudanarwa, kwarara da ƙimar kwarara;

4. Aikin mai rikodin bayanai na ultrasonic mita kwarara don sa ido da rahoto kan bayanai;
