KMCH Ultrasonic Gas Flow Meter aiki

Ka'idar aiki na KMCH Ultrasonic Gas Flow Meter ta dogara ne akan hanyar auna bambancin lokacin watsawa na gas a ƙasa da sama.An canza bambancin lokacin aunawa daidai da kwararar zuwa kwararar gas.

KMCH Ultrasonic Gas Flow Meter ya haɗa da masu canzawa na lantarki (PEA), sassan ma'auni, da na'urorin sarrafa sigina.

Sashin ma'auni na iya ƙunshi KMCH Ultrasonic Gas Flow Meter, ko kuma wani sashi na bututun da ke akwai (ƙirar ƙirar).Na'urar sarrafa siginar tana samar da masu watsawa da aka bayar wa KMCH Ultrasonic Gas Flow Meter kuma tana samar da siginar fitarwa ta yau da kullun don watsawa da yawan gas da girma a cikin yanayin aiki.

A cikin sigar da ke da ƙididdigar ƙididdiga, na'urorin sarrafa sigina suna kuma karɓar siginar yanzu daga na'urorin sarrafa zafi da matsin lamba kuma suna lissafa kwararar ruwa, ƙimar zafi a ƙarƙashin yanayi na yau da kullun kuma suna rubuta karatu a cikin rajista.

Dangane da version, zirga-zirga mita iya haɗa da zirga-zirga shirya na'urori:

• Linear sassa ciki har da wuraren da aka shigar da zazzabi da kuma matsin lamba firikwensin

• A kwararar mai daidaitawa da kawar da tasirin juriya na gida

• Gas tsabtace na'urar - shawarar don gurbataccen gas

• Silencer - Shigar da lokacin ƙididdigar bayan mai daidaitawa mai matsin lamba wanda ke aiki a ƙarƙashin yanayin ƙididdigar gas yana ba da shawarar amfani.
