I-Transit-Time ye-ultrasonic flowmeter ephathekayo, iphathwa ngesandla kwaye igxininiswe phakathi kweenzuzo kunye nokungalunganga kokuthelekisa?

I-1) Iimpawu zokulinganisa: ukusebenza komlinganiselo we-flowmeter ephathekayo kunye nesandla kubhetele.Oku kungenxa yokuba iimitha zokuhamba eziphathwayo neziphathwa ngesandla zisebenzisa unikezelo lwamandla ebhetri, kwaye umbane omileyo okanye oxhonywe eludongeni ohambayo usebenzisa unikezelo lwamandla ombane we-AC okanye we-DC, nokuba ukusetyenziswa kobonelelo lombane lwe-DC, lusuka kuguqulo lwe-AC.Ubonelelo lwamandla e-Ac lunempembelelo ethile ekusebenzeni komlinganiselo, kwimeko yesignali yesivamvo esibuthathaka, iziphumo zomlinganiselo wezixhobo eziphathwayo neziphathwa ngesandla zingcono.

I-2) Ukuthelekiswa kombane wombane: izixhobo eziphathwayo kunye nezixhobo ezihambayo eziphathwayo zisebenzisa ngokulula ngakumbi.I-flowmeter emileyo ifuna unikezelo lwamandla lwangaphandle lwe-24VDC okanye i-220VAC AC amandla, imitha yokuhamba ephathwayo kunye nesandla esiphathwayo sebenzisa amandla ebhetri yangaphakathi, imitha yokuhamba ephathekayo inokusebenza iiyure ezingama-50, i-flowmeter yohlobo oluphathwa ngesandla lunokusebenza iiyure ezili-12.3) Ukulinganisa ubushushu: i-flowmeter esisigxina kunye nephathwayo inokongeza iperi ye-Pt1000 ukuphumeza umlinganiselo wobushushu, i-flowmeter ephathwayo ayinamsebenzi wokushisa.

I-4) Iinketho zemveliso: iinketho ezimiselweyo ze-flowmeter ze-ultrasonic zingaphezulu, ezifana ne-4-20mA, i-OCT, i-relay, i-RS485, umsebenzi wokugcina idatha, i-HART, i-wireless transmittance kunye ne-GPRS;

imitha yokuhamba ephathwayo, kukuzikhethela nje kwi-4-20mA, i-OCT, i-relay, i-RS485, idathaUmsebenzi wokugcina;I-OCT, i-RS232 kunye nokugcinwa kwedatha kuyakhethwa kuhlobo oluphathwa ngesandla.
