Izi zikuphatikizapo chithandizo chokwanira cha mapaipi oyandikana nawo kuti achepetse kugwedezeka kwadongosolo. Mabungwe a kukula kwa chitoliro chomwecho ndi ma valve odzipatula a mpira akhoza kuikidwa kuti athetse kuchotsa ndi kugwiritsira ntchito zipangizo, ngati kuli kofunikira.

Chizindikiritso cha Chipangizo

Zathaview
ME Transmitter ndi mawaya awiri a loop-powered flow transmitter, yokhala ndi 4-to-20mA. Chotumizira ichi chimagwiritsa ntchito chosindikizira cha maginito chomwe sichimalumikizana poyezera kusuntha kwa shaft/pointer pamayendedwe wamba a UFM. Ndi gawo lowonjezera ku SN/SM/SH,MN/MM/MH,LL/LP/LH,LN/LE ndi XHF ma flow flow meters monga opangidwa ndi Universal Flow Monitors, Inc. ME Transmitter ilowa m'malo mwa zitsanzo zakale. Ma Transmitters a Digital omwe adagwiritsa ntchito potentiometer, kupereka kulondola kopitilira muyeso ndikusunga 100%. Kutulutsa kwa analogi kwa chipangizochi kumakhala kofanana ndi kuyenda pamitundu yogwira ntchito yamitundu yonse yothandizidwa.

Process Interface

1.  Maginito Sensors
   Pali masensa awiri omangika muholo omwe amayezera kuzungulira kwa maginito okhazikika omwe amakwezedwa pa shaft ya flowmeter. Pamene shaft imazungulira ndi kutuluka, masensa amapereka zowerengera za analogi zomwe zimasinthidwa kukhala mtengo wa digito ndi A / D converter. Makhalidwe a digito amasinthidwa ndi microcontroller ndi mzere, ndipo kenako amasinthidwa kukhala zotsatira za analogi kudzera pa chosinthira cha D/A chapakati pa 4 mpaka 20 mA.
2. Host Interface: Njira Yoyenda
   Mawaya awiri a 4-20mA omwe amalumikizana nawo amalumikizidwa ndi ma terminals awiri pa bolodi yoyendera ma transmitter. Kutengera ndi zomwe zimagwiritsidwa ntchito, imodzi mwazinthu ziwirizi zimaperekedwa kwa wiring wakumunda.
   Mzere wachiwiri wa terminal kutali ndi PCB (wokwezedwa m'chipinda chosiyana cha flowmeter) ndipo walembedwa L+ ndi L-. Waya wofiyira umalumikiza chothera (+) pa PCB kupita ku L+ ndipo waya wakuda amalumikiza chothera (-) pa PCB kupita ku L-.

Izi ndizokhazo zomwe zimatuluka kuchokera ku transmitter iyi, zomwe zikuyimira kuyeza kwa kayendedwe ka kayendedwe kake, kamene kamakhala ndi mzere ndi masikelo malinga ndi momwe chidacho chimapangidwira. Kutulutsa uku kumafanana ndi Primary Variable. Kulankhulana kwa HART kumathandizidwa pa loop iyi.

Mzere wotsimikizika wamtali waperekedwa. Kukwezeka kwa 24mA kumatha kuwonetsa kusakwanira kwa chipangizocho. Zomwe zilipo panopa zikuwonetsedwa mu tebulo ili m'munsimu.
