I-CTD Hydrological Sensor yokujonga umgangatho wolwandle namanzi

Ukuqonda indlela iipropati zamanzi ezitshintsha ngayo ngobunzulu, ubushushu, kunye nokuqhuba kwayo kubalulekile kuphando lwe-oceanographic kunye ne-hydrological.

Nokuba bajonga amanzi aselunxwemeni, baphanda ukujikeleza kolwandle, bafunda ngeendawo zamanzi acocekileyo, okanye benza uphando lomgangatho wamanzi, abaphandi bafuna imilinganiselo ethembekileyo evela kubunzulu obahlukeneyo ngaphakathi kwikholamu yamanzi.

I-CTD Hydrological Sensor inika isisombululo esisebenzayo kule njongo.

I-CTD imele i-Conductivity, i-Temperature, kunye ne-Depth. Ngokulinganisa ezi parameters zintathu zisisiseko, i-CTD sensor inokunceda abaphandi ukuba bachaze iimpawu zomzimba zamanzi kwaye baqonde indlela ubuninzi bamanzi obutshintsha ngayo kuyo yonke ikholamu yamanzi.

Izisombululo zokubeka esweni amanzi ze-CTD zeFrankStar zenzelwe ukusetyenziswa kolwandle, okusingqongileyo, amanzi, kunye nolwandle apho kufuneka khona ukujongwa ngokuchanekileyo kwamanzi kunye nekholamu.

Yintoni i-CTD Hydrological Sensor?

I-CTD Hydrological Sensor sisixhobo esisetyenziswa phantsi kwamanzi esenzelwe ukulinganisa iimpawu ezintathu ezisisiseko zamanzi:

C — Ukuqhuba
T — Ubushushu
D — Ubunzulu

Ezi zilinganiso zibonelela ngolwazi olubalulekileyo malunga neempawu zomzimba zomzimba wamanzi.

Ukuqhuba kombane kunxulumene ngokusondeleyo noxinzelelo lwee-ions ezinyibilikisiweyo emanzini kwaye kungasetyenziselwa ukumisela ubutyuwa kwiindlela zokusetyenziswa kolwandle.

Ubushushu buchaza imeko yobushushu bamanzi.

Ubunzulu bubonisa indawo ethe nkqo ye-sensor kwikholamu yamanzi kwaye buqhele ukufumaneka kwiimilinganiselo zoxinzelelo.

Xa zizonke, ezi parameters zibonelela ngeprofayili esisiseko yendalo yasemanzini.

Imele ntoni i-CTD?
Ukuqhuba

Ukuqhuba kombane kubonisa amandla amanzi okuqhuba umsinga wombane.

Ngenxa yokuba amanzi olwandle aneetyuwa kunye nee-ion ezinyibilikisiweyo, ukuhanjiswa kwamanzi kunika ulwazi oluluncedo malunga nokuba atyuwa kangakanani.

Utshintsho kwindlela esebenza ngayo i-conductivity lunokunceda ekuchongeni umahluko phakathi kobuninzi bamanzi kunye nokuxubana kwamanzi acocekileyo namanzi olwandle.

Ubunzulu

Ulwazi olunzulu luchaza apho i-sensor ikhoyo ngaphakathi kwikholamu yamanzi.

Ubunzulu bunokufunyanwa ngokusebenzisa imilinganiselo yoxinzelelo, okuvumela abasebenzisi ukuba bakhe iiprofayili ezithe nkqo zokuqhuba kunye nobushushu.

Iprofayili ye-CTD ingabonisa indlela iipropati zamanzi ezitshintsha ngayo ukusuka kumphezulu ukuya emanzini anzulu.

Isebenza njani i-CTD Hydrological Sensor?

Inkqubo eqhelekileyo yokulinganisa i-CTD iqala xa isixhobo sifakwa emanzini.

Njengoko i-CTD isiya ezantsi, ii-sensors zayo zihlala zilinganisa ukuhanjiswa kombane kunye nobushushu, ngelixa i-sensor yoxinzelelo irekhoda ubunzulu obuhambelanayo.

Idatha ephumayo ingamelwa ngolu hlobo:

Ubunzulu → Ukuqhuba + Ubushushu → Uhlalutyo lweTyuwa kunye neKholamu yamanzi

Ngexesha lophando lweprofayili, isixhobo sinokuthotywa ukusuka kumphezulu siye kubunzulu obujoliswe kubo size sithathwe.

Idatha ephumayo inika iprofayili ethe nkqo yekholamu yamanzi.
