1. Txij li thaum lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub electromagnetic flowmeter yog raws li Faraday txoj cai ntawm Electromagnetic Induction, nws cia siab rau cov dej conductive ntws los ntawm cov yeeb nkab los txiav hla cov magnetic teb kab. Kev teeb tsa cov nplhaib hauv av ua haujlwm kom ntseeg tau tias cov kua dej hauv cov yeeb nkab yog qhov zoo hauv av. Qhov no ua raws li cov peev txheej siv ntawm lub sensor-nrog rau ntawm lub converter / amplifier- nrog rau qhov muaj peev xwm ntawm cov kua tau ntsuas, yog li kuj sib piv nrog lub peev xwm hauv av. Qhov kev teeb tsa no tau lees paub qhov ntsuas qhov tseeb, ua kom lub zog ruaj khov ntawm cov flowmeter, thiab txo qhov cuam tshuam ntawm cov khoom sab nraud- xws li hluav taws xob nrov nrov - ntawm qhov ntsuas ntsuas.
2. Grounding rings zoo tshem tawm cov hluav taws xob zoo li qub nyob rau hauv lub tshuab hluav taws xob electromagnetic flowmeter thiab hloov cov stray tam sim no nyob rau hauv lub raj ntsuas ncaj qha mus rau lub ntiaj teb. Qhov no tiv thaiv kev sib kis ntawm cov teeb liab tsis raug, yog li zam cov teeb meem xws li cov ntaub ntawv hloov pauv hauv lub flowmeter converter, lub tswb "dab laug" thiab tsis muaj kev nyeem ntawv tiav.
3. Grounding rings yog tshwj xeeb yuav tsum tau thaum lub pipeline nyob rau hauv uas lubelectromagnetic flowmeteryog ntsia yog tsim los ntawm cov ntaub ntawv xws li: uPVC, PVC, PE, PPR, ABS, FRP / GRP, PTFE, los yog PIR pre-insulated piping.
